The forecast for the June–July 2026 aerial culling operation is primarily driven by the “outside view” of the NSW Government’s legal mandate. With a legislated target to reduce the wild horse population to 3,000 by mid-2027 and a May 2026 estimate showing up to 16,411 horses remain, the NPWS is under extreme pressure to execute large-scale removals. The gap between the best population estimate (10,309) and the target is approximately 7,300 horses. To reach this goal across the remaining operational windows before mid-2027, NPWS likely needs to average between 1,000 and 1,500 horses per major multi-week block.
The “inside view” relies on historical operational capacity. Since late 2023, 6,041 horses were culled via aerial shooting. This demonstrates that when the program is active, the NPWS has the logistical capability to remove thousands of animals. The June 9 to July 11 operation spans 32 days across two major sectors (Northern and Southern). Even accounting for non-flying days due to winter weather, a daily removal rate of 50–70 horses on active days makes a four-digit total highly probable.
I have weighted the primary scenario (successful high-intensity cull) at roughly 75%. This reflects the government’s stated intention to use the lower-end population estimate to guide aggressive control measures in 2026. A secondary scenario (20-25% weight) accounts for significant operational friction. The alpine environment in June and July is characterized by snow, fog, and high winds, which can drastically reduce the number of safe flying hours. Furthermore, organized activist efforts, including threats of laser interference and park incursions, may force temporary pauses or localized cancellations, potentially dragging the reported figure below 1,000.
The final prediction of 1,230 horses (with a 50% HDI of 910 to 1,570) reflects the convergence of these factors. It assumes a productive but weather-constrained operation that makes a significant initial dent in the 7,300-horse removal requirement, without assuming perfect execution given the high level of public and environmental friction. The possibility of no report or total cancellation is included but treated as a low-probability tail event.
The question asks what official NPWS/ministerial horse-specific aerial-shooting total will be reported for the June 9–July 11, 2026 Kosciuszko operations. Forecasters agree the resolution hinges both on operational throughput (historical analogues show NPWS can remove thousands in multi-week campaigns — e.g., ~2,179 over Apr–May 2024 and 270 in Nov 2023) and on whether a timely official horse-specific figure is published (the parliamentary question due July 2 and the rules that resolve no-report to 0 by Aug 11 are high-signal near-term items). All teams downweight the highest 2024-like rates because of known June–July winter weather constraints, signs of poor weather around Mount Kosciuszko, prior heavy northern culling reducing local densities, and the alerts’ “all feral animals” wording that could spread effort across species. They place most central mass around roughly 1,200–1,600 horses, while assigning meaningful lower-tail probability to very low counts or 0 if no official report/cancellation occurs, and a smaller but non-negligible right tail for an intense campaign exceeding ~2,500. Key remaining uncertainties are actual flight days/weather, whether effort is horse-prioritized, legal/political interruption, and reporting/delivery timing of NPWS disclosures. Forecasters recommend watching the July 2 parliamentary answer and any post-operation NPWS/ministerial update as decisive new evidence.
Forecast: Probability distribution:
We are forecasting the final official NPWS/Minister figure (by 11:59pm AEST Aug 11, 2026) for horses culled via lethal aerial shooting during the Jun 9–Jul 11, 2026 operation. Key drivers are (i) operational effort (aircraft hours, days flown, focus on horses vs other ferals), (ii) winter weather/visibility in the alpine zone reducing flyable days, (iii) horse density and search time as herds become harder to find, and (iv) political/administrative disruption risk (legal or safety stoppages) plus the small but real resolution rule that “no report by deadline” resolves to 0.
Across analysts, the most solid anchor is an official reference-class point: the May–Jun 2024 aerial shooting period reported at 1,521 horses (parliamentary/official reporting cited by Forecaster 3). Compared to that, the 2026 window is later in winter (downward pressure) but appears broader in geographic scope (north/central plus southern window) and under renewed urgency after the May 2026 population survey and legal mid-2027 target (upward pressure). Forecaster 2’s median (~950) may underweight the historical “like-for-like” tally and the expanded scope; Forecasters 1 and 4 may overweight urgency and/or an unverified early “600 killed” claim, pushing medians high. Netting these effects, I center slightly below-to-around the 2024 benchmark, but not as low as 950: median ~1,400, with a wide interval reflecting weather and execution variance.
Tails: I include a small open-below chance (<190) for severe weather, interruption, or a reporting failure (which would resolve to 0), and a meaningful but not dominant open-above chance (>2,509) if there are unusually many flyable days and high encounter rates across multiple zones.
An amateur forecast is likely to (a) anchor on the statutory “reduce to 3,000” target and extrapolate to a very large single-operation kill count, or (b) anchor on controversy/claims of low horse numbers and predict only a few hundred, and often won’t explicitly represent open-tail possibilities (very low counts if halted/not reported; very high counts if operations run exceptionally well). This synthesis instead anchors on an official historical benchmark (the 1,521-horse 2024 aerial period), adjusts for later-winter constraints and broader 2026 scope/urgency, and keeps calibrated uncertainty with explicit lower/upper tails. I’m moderately confident this is better-calibrated than any single analyst’s distribution because it downweights the least-supported extremes (very low median; very high median driven by weak partial-count evidence) while preserving meaningful tail risk.
Forecast rationale (numeric):
— Iteration 1 — The forecasts converge on a substantial but highly uncertain cull, driven by a mix of historical precedent, operational length, and winter weather constraints.
The collective reasoning suggests the NPWS report will most likely fall in the low-to-mid four figures, with a central expectation roughly around 1,000–1,600 culled horses, but with substantial uncertainty from winter weather, logistics, and the possibility of delayed or absent reporting.
— Iteration 2 — Overall, the forecasts converge on a mid-to-low four-digit outcome, centered around roughly 800–1,150 culled horses, with a broad plausible range extending from a few hundred to roughly 2,500+.
The collective reasoning suggests a likely reported cull in the vicinity of about 1,000 horses, with uncertainty driven mainly by weather, operation intensity, and whether NPWS publishes a discrete operation-specific count on time.
— Iteration 3 — Across the forecasts, the main expectation is for a substantial but not extreme aerial cull—most likely around 1,000 to 1,500 brumbies, with a broad plausible range of roughly 600 to 1,500+ if the report is published on time.
The collective reasoning points to a moderately large, operationally constrained aerial cull, centered near about 1,000–1,400 horses, with a non-trivial chance of a zero reported value if the official report is not released by the deadline.
Here is a synthesis of the qualitative reasoning shared across the rationales:
Statutory Pressure and Operational Urgency Forecasters universally agree that the NSW National Parks and Wildlife Service (NPWS) is operating under intense legislative pressure to meet a strict, legally mandated population reduction target by mid-2027. Following a recent rebound in the wild horse population due to a temporary culling pause, the NPWS faces a massive deficit. Consequently, the June–July 2026 window is expected to feature a highly aggressive, militarized, multi-helicopter operation designed to clear a large portion of this excess population.
Weather Constraints and Logistical Bottlenecks While the urgency is high, operational output will be heavily restricted by the realities of the Australian alpine winter.
The Reporting Deadline Risk (The “Zero” Scenario) A dominant factor across all rationales is the strict reporting deadline mandated by the resolution criteria. If the NPWS fails to publish an official tally within exactly one month of the operation concluding, the question resolves to zero. Forecasters note a substantial bureaucratic risk that standard data verification processes, political sensitivities, or delayed parliamentary inquiries could push the publication of the final report past the deadline. While intense public scrutiny and upcoming parliamentary debates highly incentivize the Environment Minister to release a timely press release or interim figure, the risk of a delayed report—and thus a zero resolution—remains a major structural constraint on the forecasts.

The research reports that an NPWS aerial shooting operation begun on 9 June 2026 and scheduled to run to 11 July 2026 is currently underway but that no official culling numbers from this specific operation have yet been published (resolution of numbers expected by an 11 August 2026 deadline). It cites a 2025 peer‑reviewed population survey estimating 6,476–16,411 wild horses in Kosciuszko National Park (best estimate 10,309), a NSW legislative requirement to reduce the population to exactly 3,000 by mid‑2027, and historical removal figures including ~6,041 horses killed by aerial shooting during 2023–24 (6,686 total removed) and 270 horses killed in a November 2023 operation. The research converts those figures into removal targets (e.g., ≈7,300 removals needed from the 10,309 best estimate to reach 3,000) and notes a news prediction that 3,000–10,000 could be shot in the first week of July.
The research also records that no prediction markets were found for this event, and it lists major uncertainties affecting outcomes and reporting: contested population methodologies, alpine/weather constraints, public opposition and legal/political pressure, possible operational date adjustments, and risks of delayed or ambiguous official reporting. Using outside‑view anchors and past base rates, the researcher outlines conservative, moderate, aggressive, and upper‑bound scenarios and concludes the most plausible reference class is the 2023–24 cumulative operations; the research’s stated likely range for this June–July 2026 operation is about 500–3,000 horses, with substantial uncertainty and several resolution risks noted.

If you can provide the original reference list or links for items [1],[2], etc., I can copy those URLs verbatim.
Based on my comprehensive research, here is a detailed rundown for forecasting the NSW brumby aerial culling operation outcome:
As of June 29, 2026 (the current date), the aerial shooting operation is currently underway. The operation began on June 9, 2026, and is scheduled to conclude on July 11, 2026 [1][11][23]. However, I found no official reports yet published with actual culling numbers from this specific operation, which is expected given the resolution deadline is August 11, 2026.
The 2025 peer-reviewed population survey estimated 6,476 to 16,411 wild horses (best estimate: 10,309) in Kosciuszko National Park [1][2][20][25]. This represents a dramatic increase from the 2024 estimate of 2,131 to 5,639 horses [1][20]. The NSW government has a legislative mandate to reduce the population to exactly 3,000 by mid-2027 [1][2][6][7][8].
Previous Aerial Shooting Operations:
Key Quantitative Benchmarks:
Operation Efficiency Metrics:
The 2023-2024 operations removed 6,041 horses via aerial shooting over approximately one year (with pauses). The current operation has a concentrated timeframe of approximately 33 days (June 9 - July 11, 2026), suggesting a more intensive operational tempo.
No prediction markets identified. My searches found no active prediction markets on Polymarket, Manifold, Kalshi, or other platforms specifically forecasting this brumby culling operation’s outcome. This lack of market data means there’s no liquidity or volume metrics to assess reliability.
Major Sources of Uncertainty:
Population Methodology Disputes: Critics strongly contest the population estimates, with some advocates claiming actual numbers are far lower than government figures [1][4][11]. One advocate noted: “If there were 23,535 horses in 2022, and only 9,000 were formally removed, and the 2024 survey found fewer than 3,000 – where did 11,000 horses go?” [4]
Operational Constraints:
Outside-View Anchors:
Resolution Risks:
The most reliable reference class is the 2023-2024 cumulative operations (6,041 horses over ~1 year). However, this June-July 2026 operation appears more concentrated and urgent given the mid-2027 deadline. The base rate range likely falls between 500-3,000 horses for this specific operation, with significant uncertainty due to operational, political, and methodological factors. No prediction markets provide external validation of these estimates.
I accept the Round 5 critic’s main adjustment. The best update is not “April 2024 peak throughput scaled to 33 days,” but a mixture of: demonstrated high capacity, a likely internal control target, poor June/early-July weather, and a real reporting tail. The current NPWS alerts confirm the relevant windows are broad feral-animal aerial-shooting closures: northern/central Kosciuszko from June 9–30 and southern Kosciuszko from June 29–July 11. (nationalparks.nsw.gov.au)
The biggest valid criticism is weather. Thredbo Village observations show 262.4 mm of rain in the first 29 days of June 2026, including major rain days during the June 9–30 operating window; the short-term forecast also has rain/drizzle, rain, showers, breeziness, and snow/rain risk through the early southern phase. That makes “north/central did moderate work, south adds relatively little” more likely than I had in earlier rounds. (bom.gov.au)
I still do not want to collapse the right tail. The official April–May 2024 parliamentary answer reports 3,429 horses aerially shot in northern Kosciuszko, with multiple high-output days, proving that >2,500 can happen operationally. But the counter-anchors are now more salient: March 2024 southern operations removed 534 horses in the first 15 closure days, and the May–June 2024 answer shows a sharp slowdown and explicitly says winter weather slowed the program. (parliament.nsw.gov.au)
The policy signal still supports a serious, non-symbolic operation: the 2025 survey estimated 10,309 horses across survey blocks, with a 6,476–16,411 interval, and NSW says control is needed in all management areas. But the June 2026 parliamentary answer says the 2026 program will use the lower end of a conservative estimate, which is exactly the kind of language that implies a quota/stop-rule rather than “shoot as many as possible.” (environment.nsw.gov.au) A planned November 2026 aerial-control window also reduces the need to force the whole reduction into this winter operation. (nationalparks.nsw.gov.au)
New factor I weight a little more: the June 2026 carcass-monitoring report describes the comparable April/May 2024 monitored event as 2,179 horses over about 400 km², and notes cooler-month carcass persistence and red-fox use. I do not treat that as a hard cap, but it reinforces a practical/political reason to trim the 4,000–7,000 tail. (environment.nsw.gov.au) Reporting risk remains: NPWS says control-program summaries are made public only “from time to time” and operational details are not generally released, so I keep a small but material 0-resolution tail for no qualifying official figure by August 11. (environment.nsw.gov.au)
Conditioning on the question not being annulled/declared ambiguous, I now put roughly 7–8% below 199.5 and about 26% above 2,499.5. Median around 1,750–1,800.

I agree with the critic’s main correction: the April–May 2024 northern operation materially changes the upper tail. An official parliamentary answer says 3,429 wild horses were aerially shot from 1 April to 3 May 2024, all in northern Kosciuszko, with single-day tallies as high as 537, 386, and 306. That is a much better capacity anchor than only using the March 2024 southern figure of 534 in 15 calendar days. It makes my previous ~11% above 2,499.5 too low. (parliament.nsw.gov.au)
I still do not fully adopt the critic’s 25–30%+ high-tail framing without caveats. The current June–July notices are for aerial shooting of all feral animals, not horse-only operations, and the southern phase begins in poor alpine flying conditions: sleet/freezing rain, snow/rain, wind, and very windy days are in the current Mount Kosciuszko forecast. The current operation also is not the last obvious campaign window: NPWS already lists another November 2026 aerial-control closure, so June–July need not do the whole job. (nationalparks.nsw.gov.au)
The strongest new insight for me is that the 2025 survey’s block-level numbers support a real high-side scenario: MRDS estimates are about 5,293 horses in the northern block and 4,677 in the southern block, so both current closure regions plausibly contain enough horses for a multi-thousand result if flying days are productive. That argues against treating 2,500+ as a rare “tail only” outcome. (environment.nsw.gov.au)
Reporting risk remains a genuine separate issue. NPWS says control summaries are made public only “from time to time” and operational details are not normally released, but past parliamentary answers have produced very specific aerial-shooting totals, and a current question due July 2 asks about the June 9–30 and June 29–July 11 operations. So I keep a chunky low/reported-zero tail, but I do not let it dominate the forecast. (environment.nsw.gov.au)
Net update: I move the median up from ~1,230 to ~1,550, increase probability above 2,499.5 to roughly 25–26%, and put probability below 199.5 at roughly 11–12%. This is a meaningful upward revision, but still below the critic’s most aggressive framing because of winter weather, all-feral-animal wording, future operation staging, and official-report uncertainty.

Model’s Answer: The unit here is horses, meaning the official integer count of wild horses reported as culled via the June–July 2026 aerial shooting operation.
Step one is to anchor on the best official evidence, not the loudest advocacy. The most important sources are the NSW Environment/NPWS releases and implementation pages, then mainstream reporting that clearly cites those official figures. Those sources tell us a few key things.
The 2025 survey released in May 2026 gave a very wide official range of 6,476 to 16,411 horses, with a best estimate of 10,309. The same official material says 6,686 horses had been removed since late 2023, including 6,041 by aerial shooting. That means aerial shooting has already been used at substantial scale, so a very small number for this operation would need a special explanation such as cancellation, heavy interruption, or no official report by the deadline.
Step two is to estimate what a one-month winter aerial operation can plausibly do. The strongest hard operational datapoint in the research is that in 2023, 270 horses were shot over two 8-hour flying days, or about 135 per effective flying day. The 2024 campaign appears to have been much larger overall, with thousands removed in April–May 2024, mostly via culling. So the machinery exists for a large count.
But I do not want to simply project the biggest prior pace forward. June–July in Kosciuszko is winter, which should reduce the number of effective flying days through snow, wind, cloud, and safety constraints. Also, density may be lower in accessible areas than during earlier waves, and the government is not trying to eradicate to zero. Those factors pull the center down from the most aggressive historical scenarios.
Step three is to combine those forces. My base case is that the operation is completed and officially reported by the deadline, and that it ends up looking like a meaningful but not maximal winter campaign. That points to a central band roughly around 1,100 to 2,200 horses, with a median around 1,400.
The biggest swing factor is not the exact daily kill rate; it is whether there is a timely official figure by August 11. The fine print makes that crucial, because no report by the deadline resolves to 0. I think that is a real left-tail risk, though not the most likely outcome. NSW has released cumulative figures before, and this operation is politically salient, so I still lean toward a reported numeric result rather than silence.
The assumptions that matter most are these.
Step four is the reporting assumption. I am assuming NPWS or the minister will publish, state, or otherwise officially confirm a specific figure by the deadline. I put the chance this assumption fails at about 12%. If it fails, the question resolves to 0, which creates a chunky lower tail.
Step five is the operations-intensity assumption. I am assuming the June 9 to July 11 campaign gets a moderate number of effective flying days and is not badly truncated by weather, legal action, or safety concerns. I put the chance this assumption is materially wrong at about 25%. If wrong on the low side, the result could land in the low hundreds. If wrong on the high side, a longer or more efficient campaign could push well above 2,500.
Step six is the accessible-population assumption. I am assuming the official survey is directionally correct enough that there are still plenty of horses available to be found and culled in operational areas, even if the precise estimate is disputed. I put the chance this assumption is materially wrong at about 20%. If the true accessible population is much lower than officials imply, the count could disappoint sharply. If the survey is understating accessible numbers in culled zones, the upper tail gets fatter.
A low outcome can happen mainly in three ways: no official report by the deadline, a heavily interrupted operation, or a surprisingly low number of accessible horses in the actual shooting areas. I put the chance of an outcome below 189.5 at about 8%.
A high outcome can happen if the government treats this as a major push after the May survey rebound, if weather windows are better than expected, and if this operation absorbs what might otherwise have been spread over multiple smaller rounds. I put the chance of an outcome above 2,509.5 at about 13%.
Overall, this is a cumulative-count question with meaningful operational precedent but poor direct visibility into the live run-rate. That argues for a broad distribution, not an overly sharp one. My median is a bit below the middle of the default range, but I keep a substantial right tail because past NSW aerial culling has shown the capacity to remove horses quickly when conditions permit.

The statutory target to reach 3,000 horses by mid‑2027 imposes a finite, staged removal obligation rather than an open-ended operation.
Survey-based abundance estimates are large and imprecise, so operational plans must reconcile a wide population range with a fixed legal end‑point and additional control windows later in 2026.
Historical aerial throughput shows capacity for hundreds of removals on usable days, anchoring a four‑digit central expectation for this long window.
Winter weather, multi‑species mission scope, and operational limits reduce productive flight days, pushing the center lower than a full 2024 replay.
A short dry spell in early July could produce a concentrated burst of removals, while poor visibility or gusty winds could truncate the operation.
Administrative caps, retention‑area commitments, and the availability of a November control window create strategic incentives to modulate effort now rather than exhaust capacity.
The single largest resolution risks are reporting and aggregation choices, since an officially published, operation‑specific count may be withheld or folded into broader program summaries.
Operational unknowns — exact helicopter days, hours flown, and allocation between species — leave a broad central range centered near the low‑to‑mid one‑thousands and substantial tail risk on both sides.
Forecast: median = 1052.4797 wild horses culled (June–July 2026 aerial shooting, as reported by NPWS/Minister).
I anchor on three official facts. First, the current management plan requires the wild horse population across retention areas to be reduced to 3,000 by 30 June 2027, while removal areas are to be kept at zero. Second, NPWS alerts show the relevant 2026 aerial-shooting window runs from 9 June to 30 June in parts of Kosciuszko National Park and from 29 June to 11 July in southern parts of the park. Third, NPWS reported that from 24 November 2021 to 31 December 2025, 9,198 horses had been removed, including 6,041 by aerial shooting. (environment.nsw.gov.au)
The key live uncertainty is not whether horses will be targeted, but how aggressively NPWS will push this specific winter operation. The May 2026 government release says the 2025 survey estimated 6,476 to 16,411 wild horses in the park. A June 2026 parliamentary answer further says control is needed in all management areas, including retention areas, and that the government will use the lower end of the 2025 estimate to guide the 2026 control program, taking account of removals since the survey. Even that lower bound is still 3,476 above the statutory 3,000 target, so the government’s own conservative planning case still leaves room for a substantial 2026 aerial tally. (environment.nsw.gov.au)
For execution capacity, the best official analog is 2024. The NPWS carcass-monitoring report says 2,179 horses were shot between 11 April and 27 May 2024 over about 400 km2. A parliamentary answer listing daily totals from 1 May to 14 June 2024 shows 1,521 horses shot in that span, with many zero days late in the run and an explicit note that winter weather slowed the program. That historical pattern suggests a 33-day winter window can still produce a four-figure total, but weather and terrain materially cap how much of the theoretical target can be delivered in one operation. (environment.nsw.gov.au)
The near-term forecast for Cabramurra looks mixed rather than disastrous: some rain and cloud early, followed by several mostly dry or partly sunny days from 4 July through 11 July. I treat that as modestly supportive of continued flying rather than as a major shutdown signal. This is an inference from forecast conditions, not a direct NPWS statement.
Putting those pieces together, my base case is that NPWS reports a June-July 2026 aerial-shoot total in the mid-1600s to high-1700s. I do not think the most likely outcome is as low as a few hundred, because official policy says control is needed in all management areas and the conservative survey lower bound still implies thousands above target. But I also do not think the most likely outcome is the full lower-bound excess above 3,000, because the government has said it is using the lower-end estimate to guide 2026 control and still has until 30 June 2027 to hit the statutory target. So I center the distribution around roughly 1,680, with a meaningful right tail into the low-to-mid 2000s if execution is strong and management is more aggressive, and a small left tail below 200 for disruption, underperformance, or reporting failure. That final centering is my forecast inference from the official target, survey range, prior removal totals, 2024 operational tempo, and current weather. (parliament.nsw.gov.au)
One correction to the prompt: the Kosciuszko Wild Horse Heritage Act 2018 was repealed on 3 December 2025, but the adopted wild horse heritage management plan was preserved as a plan of management until a transition date no later than 1 November 2027. NSW environment pages still state that NPWS is legally required to reduce wild horses to 3,000 by 30 June 2027. For the operation in question, official park alerts show aerial shooting in parts of Kosciuszko National Park from 9 June to 30 June 2026 and then in southern parts from 29 June to 11 July 2026, so this is effectively one contiguous June-July campaign. (parliament.nsw.gov.au)
The hardest input is not the policy target but the true number of horses available to be shot during this operation. The NSW Government’s 22 May 2026 media release summarized the 2025 survey at 10,309 horses with a 95% confidence interval of 6,476 to 16,411. But the underlying report is materially noisier than that topline alone suggests: the AIC-best MRDS retention-area estimate was 12,662 (95% CI 7,843 to 20,443), while a more conservative half-normal retention-area estimate was 9,982 (95% CI 7,186 to 13,864), and the authors explicitly noted wide confidence intervals and the possibility that 2024 abundance had been underestimated. So I do not anchor on one point estimate; I use a broad latent-abundance prior centered around roughly 10,000 but with meaningful mass both below and above that. (environment.nsw.gov.au)
History argues against a tiny result. In 2024 NPWS reported 534 horses aerially removed in the first 15 days of the southern operation from 4 March to 19 March, 3,429 horses aerially shot between 1 April and 3 May 2024, and 4,604 horses removed by aerial or ground shooting in the north between 4 April and 4 July 2024. But history also argues against simply copying 2024 into 2026: 2024 began from a higher horse population, and the 2024 northern program was partly constrained by a court-related undertaking that stopped retention-area removals after 23 May 2024. That means 2024 demonstrates capability, but it is not a clean apples-to-apples forecast template. (parliament.nsw.gov.au)
The government is clearly still relying heavily on aerial shooting. The May 2026 release said that since aerial shooting was introduced in late 2023, 6,686 horses had been removed from Kosciuszko National Park by all methods, including 6,041 through aerial shooting. At the same time, I could not find any official public target count for the current June-July 2026 operation as of 29 June 2026; an official parliamentary question specifically asking how many horses NPWS intended to kill in the 9-30 June and 29 June-11 July operations was still awaiting an answer due on 2 July 2026. So this forecast has to be inferred from capacity, abundance, and incentives rather than read off a declared target. (environment.nsw.gov.au)
My model therefore treats the latent horses available to this operation as a mixture of three plausible abundance views derived from the official 2025 material, then multiplies that by a one-operation removal fraction with an average around 20% and wide execution uncertainty. I set that average below the most intense 2024 phase because the 2026 campaign starts from a smaller and more thinned-out population and is framed as an all-feral-animal operation, but I keep a meaningful upper tail because the 3,000-horse target remains operative and the current operation spans both the earlier June zone and the southern July zone. This produces a distribution centered a little above 2,000 horses, with substantial mass in the mid-1,000s to mid-2,000s and a non-trivial right tail above 2,500 if weather and access cooperate and execution resembles the stronger 2024 phase. (auth-prd.nswparks.cloud)
My best single-number estimate is 2,040 horses reported as culled via aerial shooting during the June-July 2026 operation. (auth-prd.nswparks.cloud)
As of Monday, June 29, 2026, NPWS had scheduled aerial shooting operations in parts of Kosciuszko National Park from June 9 to June 30, 2026 in northern/central areas, and from June 29 to July 11, 2026 in southern areas. The NSW government says the legal target remains 3,000 wild horses by mid-2027. The May 22, 2026 government release reported a 2025 survey range of 6,476 to 16,411 horses in the park, and ABC reported the best single estimate as 10,309. In parliamentary answers published June 12, 2026, the government said control is needed in all management areas and that it would use the lower end of a conservative 2025 estimate, adjusted for horses removed since the survey, to guide the 2026 program. (nationalparks.nsw.gov.au)
History argues against a tiny tally. In the 2024 southern phase, NPWS reported 534 horses aerially removed between March 4 and March 19, 2024. In the north, 3,429 were aerially shot between April 1 and May 3, 2024, and 4,604 horses were removed by aerial or ground shooting between April 4 and July 4, 2024, with 3,878 of those in retention areas. By May 22, 2026, the NSW government said 6,686 horses had been removed from Kosciuszko since aerial shooting was introduced, including 6,041 by aerial shooting. (parliament.nsw.gov.au)
But 2026 is not simply a replay of 2024. The 2025 survey suggests lower horse abundance in the northern block than in October 2023, and more in the southern block. The 2025 best-estimate MRDS results were about 5,293 horses in the northern block, 339 in Snowy Plain, and 4,677 in the southern block; the report’s conservative half-normal model gave lower totals of 4,615, 263, and 3,314 respectively. That makes a 2026 total lower than the most explosive 2024 pace more likely, especially because the entire current operation is occurring in winter. NPWS itself said the 2024 program slowed due to winter weather, and the current Cabramurra forecast for June 29 to July 11 shows several cloudy/showery days before improving later in the window. (environment.nsw.gov.au)
I used a simple analog model: scale the big 2024 north and south tallies by the change in 2025-vs-2023 block populations. That produces about 2,091 horses using the 2025 best estimate and about 1,707 using the conservative half-normal estimate; applying a further 10% winter drag gives about 1,882 and 1,536 respectively. Those numbers are only rough analogs, but they anchor the plausible range. I then added some probability mass above them because the June 9 to June 30 northern/central phase has already been running for 20 days as of June 29, 2026, and because the government is under clear legal pressure to keep moving toward the mid-2027 target rather than pause after a token operation. (nationalparks.nsw.gov.au)
My central view is therefore around 1,900 horses reported as culled, with the thickest probability mass roughly from the mid-1,500s to the low-2,200s, and a meaningful but smaller upper tail above 2,500 if the first three weeks were especially productive and the southern phase also performs well. I leave a small left-tail probability for severe interruption, operational underperformance, or a missing/late official report, but because the operation is already underway that tail is now quite small. (nationalparks.nsw.gov.au)
I treat the prompt’s legal framing as somewhat slanted. Official NSW material says the Kosciuszko Wild Horse Heritage Act 2018 has been repealed, but control will continue under the existing Wild Horse Heritage Management Plan while the updated park plan is prepared. Under that plan, 32% of the park is retention area, 21% removal area and 47% prevention area, with a target of 3,000 horses in retention areas by 30 June 2027. (environment.nsw.gov.au)
The operation in question is real and already underway. NPWS alert pages show aerial shooting operations in parts of Kosciuszko National Park from 9 June to 30 June 2026 and in southern parts from 29 June to 11 July 2026, with the closure potentially shortened or extended for weather. The southern closure includes Byadbo and Pilot areas, which overlap places the management plan explicitly identifies as retention-management areas; the northern/central closures also cover areas including Goobarragandra and Bimberi. That makes this look more like a park-wide management push than a tiny mop-up. (auth-prd.nswparks.cloud)
The strongest base-rate evidence is the 2024 aerial shooting record. In an official parliamentary answer, the minister said that 3,429 wild horses were aerially shot between 1 April and 3 May 2024, across 17 listed shooting days, with 2,881 of those removed from retention management areas. That is about 202 horses per active day, and it proves NPWS can both operate inside retention areas and report a multi-thousand horse tally in a shorter window than the current June–July 2026 operation. (parliament.nsw.gov.au)
Recent stock-availability evidence is mixed but still points to plenty of horses. The official 2025 survey page gives an endorsed MRDS estimate of 10,309 horses in the survey blocks, with a 95% interval of 6,476 to 16,411, and says the higher 2025 figure versus 2024 likely reflects both some natural growth and lower detectability in 2024 rather than explosive true growth. The full 2025 report also estimates 12,662 horses in the retention areas under its AIC-best MRDS model, with a 95% interval of 7,843 to 20,443. Even allowing for survey uncertainty, that is far above the 3,000-horse target and argues against a very small 2026 tally. (environment.nsw.gov.au)
The removal history cuts both ways. Through 31 December 2025, NSW says 9,198 horses had been removed since November 2021, including 6,041 by aerial shooting. A parliamentary answer said 5,969 had already been removed by aerial shooting by 11 March 2025, implying only 72 more aerial removals from 12 March through 31 December 2025. Separately, the June 2025 Wild Horse Community Advisory Panel summary said annual aerial control operations had commenced with horses in retention areas excluded from control activities. I read that as evidence that 2025 was comparatively restrained on horses, which helps explain why a much larger 2026 catch-up operation is plausible. (environment.nsw.gov.au)
Weather is a moderate, not dominant, brake. The forecast from 29 June to 11 July for Jindabyne shows several wet or windy days early in the second phase, followed by a clearer run from about 4 July to 10 July. That should trim efficiency somewhat, but it does not look like a washout.
My model uses two scenarios. In a cautious scenario, 2026 is a scaled-down repeat of 2024 because horse density is lower than in 2024, aircraft time is shared with other feral animals, and winter weather reduces flying efficiency; I center that around 1,700. In an aggressive catch-up scenario, NPWS again shoots heavily in retention areas and uses the longer 2026 schedule to push toward the 2027 target; I center that around 2,800. I weight those scenarios 60%/40%, giving a mean forecast of about 2,140 horses. So my distribution is centered in the low-2000s, with most mass from roughly 1,400 to 3,000 and a meaningful right tail above 2,500. (parliament.nsw.gov.au)
Main risks to this forecast: (1) NPWS may devote more helicopter time than I expect to deer and pigs rather than horses, pushing the number down; (2) the 2025 survey may overstate horse abundance in the operational areas, also pushing down; (3) if the government is using the higher retention-area estimates as its operational baseline, or if weather allows near-full use of the scheduled window, the official total could easily land above 2,500 and even challenge the 2024 pace. (environment.nsw.gov.au)
The operation is officially set up as one contiguous June to July 2026 aerial-shooting program in two geographic blocks: 9 June to 30 June in northern and central Kosciuszko, then 29 June to 11 July in southern Kosciuszko. A parliamentary question published on 11 June 2026 asks the Government for the intended numbers for those exact windows, with an answer due on 2 July 2026. That suggests the public official target was not yet clearly stated in the material I reviewed, so the forecast has to be inferred from population estimates, past execution, and weather rather than from an announced quota. (nationalparks.nsw.gov.au)
The baseline stock is still large enough to support a substantial cull. NPWS says that from 24 November 2021 to 31 December 2025, 9,198 horses were removed, including 6,041 by aerial shooting. Budget-estimates answers say the same 9,198 had been removed by 1 February 2026, and that only five horses had been ground-shot since the repeal bill passed on 27 November 2025. Then, on 22 May 2026, the Government released the 2025 survey saying the survey blocks still held an estimated 6,476 to 16,411 horses and that more work was needed to meet the mid-2027 target. A June 2026 parliamentary answer also says control is needed in all management areas and that the 2026 control program will use the lower end of a conservative population estimate from the 2025 survey. (environment.nsw.gov.au)
The 2025 survey details matter. Its best MRDS estimate for the survey blocks was 10,309 horses, with block estimates of about 5,293 in the Northern block, 339 in Snowy Plain, and 4,677 in the Southern block. For retention areas, the MRDS estimate was 12,662, with about 5,204 in Northern retention, 288 in Snowy Plain retention, and 7,169 in Southern retention. Even the lower half-normal retention estimates were still roughly 4,644 in Northern retention, 205 in Snowy Plain retention, and 5,133 in Southern retention. Because the current operation covers north and central country first and southern country second, I infer that both phases still have plenty of horses available, especially in the south. (environment.nsw.gov.au)
Historical execution points to a total in the high hundreds to low thousands, not a token number. In 2024, NPWS reported 534 horses removed by aerial shooting in southern Kosciuszko from 4 March to 19 March; 3,429 aerially shot in the north from 1 April to 3 May; 1,521 aerially shot in the north from 1 May to 14 June; and 5,963 aerially shot overall by 2 August 2024. A key nuance is that 2024 late-season output was artificially damped by a Supreme Court-related undertaking: no more than 811 horses could be removed from retention areas between 9 May and 30 June 2024, and that threshold was reached on 23 May, after which operations continued only in removal areas where remaining density was lower. Since the Wild Horse Heritage Act has since been repealed, 2026 is less likely to face that exact bottleneck. That pushes me above a simple extrapolation from June 2024 alone. (parliament.nsw.gov.au)
Weather is the main downward adjustment. The Jindabyne forecast on 29 June 2026 showed rain or showers and some wind through roughly 3 July, with better conditions from 4 July into 8 July. Official answers from 2024 explicitly said winter weather slowed the program once it moved deeper into June. So I discount the raw 2024 April to May pace and assume fewer effective flying days and somewhat lower daily productivity than in the best 2024 periods. (parliament.nsw.gov.au)
Putting that together, my central view is that the final official tally is more likely to land around the upper 1,000s than around a few hundred or above 2,500. I model a small 3% mass on cancellation or no-report resolution at 0 because the rules explicitly do that if no official figure is published. I then use a low-execution scenario for weather and terrain problems, a base scenario centered around roughly 1,700 to 1,800, and a higher-output scenario reflecting the absence of the 2024 retention cap plus still-large horse numbers in both the northern and southern operational areas. That gives a distribution centered around roughly 1,750, with the thickest mass in about the 1,500 to 2,200 range and a meaningful but not dominant right tail above 2,500. (nationalparks.nsw.gov.au)
