 In response to public outcry, the Minister for the Environment, Mr Bob Debus, commissioned a study into the heritage value of horses in the park and indicated that, should the horses be found to have genuine heritage significance, they would be humanely removed from the park so that they can be managed properly in another location by people with an interest in their heritage value.In February 2002, the final report by the Heritage Working Party found that these horses had significant historical, military and cultural value.They are direct descendants of Australia's wartime cavalry horses, known as Walers, and are the only group of Australian wild horse to have proven heritage value.
