Aerial shooting to resume as brumby numbers spike in national park

Feral horse numbers in Kosciuszko National Park have surged, prompting NSW to resume aerial culling in June. Surveys estimate between 6,476 and 16,411 horses remain, up from the previous year, as the government pursues a legally mandated target of 3,000 by mid-2027.

Aerial culling is set to resume in Kosciuszko National Park after a sharp increase in the wild horse population, according to New South Wales government survey data. The 2025 survey estimated between 6,476 and 16,411 feral horses remain in the park, with a best single estimate of 10,309, as reported by both ABC Australia and The Guardian. This marks a significant rise from the 2024 count, which estimated between 2,131 and 5,639 horses.

NSW Environment Minister Penny Sharpe said the data confirms the need for continued management. "There's still too many horses in the park and we're just going to have to do more," she said, as quoted in both reports. The state government is legally required to reduce the horse population to 3,000 by mid-2027.

Coverage comparison

Both ABC Australia and The Guardian report similar facts but frame the story with different emphasis. ABC Australia presents the issue neutrally, describing the population increase and the resumption of aerial culling in June. The Guardian adopts a more critical stance, using language like "surged" and quoting conservation advocates who describe the park as "not a horse paddock." Both sources cite the same government survey data and quote the same officials and experts.

Key Claims

Aerial culling to resume: Both sources report that aerial culling will recommence in June, following a pause in 2025 after the lower 2024 figures were published. According to ABC, the pause was due to the reduced numbers, and the method will now be used alongside rehoming and trapping.

Fertility control trial: The NSW National Parks and Wildlife Service is investigating reproductive control methods as a potential tool, as reported by ABC. Minister Sharpe mentioned using darts for fertility control, though she noted the population is currently too high for that approach to be effective alone.

Legal requirement: The state government is legally obligated to reduce horse numbers to 3,000 by mid-2027, a fact reported by both sources. This target aims to balance the heritage value of brumbies with the need to protect the park's fragile alpine environment.

Conservation criticism: Conservation advocates, including Jack Gough, CEO of the Invasive Species Council, have criticized the government's management plan, particularly the retention zones that allow thousands of horses to remain. Gough argues the rebound in numbers reflects the lack of control work in 2025 and shows culls should occur annually, according to The Guardian.

Perspectives

Government perspective: Minister Sharpe emphasizes the need for continued management and acknowledges the challenge of balancing horse heritage with environmental protection. She notes early signs of vegetation recovery in areas where horse numbers have been reduced but stresses that overall numbers remain too high.

Conservation advocates: Jack Gough welcomes the return of aerial culling, calling for urgent action. The Guardian reports his view that the rebound in numbers demands a rethink of retention zones and more consistent control measures.

Scientific community: The survey methodology, described as "mark recapture distance sampling," relied on helicopter-based observers counting groups of horses. Minister Sharpe noted a preference for publishing a population range rather than a single estimate due to the difficulty of counting moving animals over a large area.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
