The NSW Parliament has passed a bill introduced by Independent MP Dr Joe McGirr to repeal the Kosciuszko Wild Horse Heritage Act, which had protected feral horses (brumbies) in the Snowy Mountains. The new law prioritizes scientific evidence over ideology, aiming to protect endangered species, alpine wetlands, and drinking-water catchments by allowing more active management and culling of feral horses. The bill passed with broad support from Labor, Greens, and most Liberals, despite opposition from some Nationals, Liberals, and animal rights advocates who view the brumbies as an important part of Australian heritage.

Supporters argue the repeal restores environmental integrity and ensures the preservation of the fragile alpine ecosystem for future generations, benefiting native species like the broad-toothed rat and corroboree frog. Critics, including Liberal MP Rachel Merton, warn that the legislation will lead to cruel mass killings and the loss of cultural heritage associated with the brumbies. Nonetheless, the bill reflects a shift toward prioritizing ecological health and professional park management over symbolic protections for invasive species.
