THE state opposition has pledged to stop Labor's extermination of Victoria's brumby population.

State Liberal member for Eildon Cindy McLeish said the coalition's plan is good news for the many Victorians who support the protection of brumbies.

The coalition plans to shift focus to rehoming and veterinary intervention to manage the brumby population, standing in stark contrast to Labor's plan for total eradication of the brumbies.

"The coalition will put an end to Labor's cruel and inhumane plans of killing brumbies through aerial and ground shooting," Ms McLeish said.

"We will completely rule it out.

"The coalition will conduct a thorough and more accurate assessment of the brumby population.

"The coalition will put in place population management methods that focus on rehoming and veterinary intervention, and liaison with New South Wales to coordinate efforts across state borders."

Ms McLeish has joined a number of protests on the steps of state parliament, standing with Victorians who are furious with Labor's massacre.

"We cannot ignore communities' objections to culling these brumbies," Ms McLeish said.

"The city centric Labor Government's ignorant approach will not deliver good outcomes for the environment or for farmers.

"Abandoned carcasses that are left to rot will only serve to feed up destructive and vicious pest animals, like wild dogs.

"This will increase wild dog activity and breeding, making it more difficult for farmers to protect their livestock from wild dog attacks.

"In parliamentary budget hearings recently, the Labor Government admitted that it was working towards 'eradication (of brumbies) over the forward years'."

An action plan outlined by Parks Victoria recommends reducing brumby populations through a combination of trapping, rehoming, and ground–shooting, with a spokesperson confirming that the plan was under way.

Parks Victoria has not confirmed how many horses – if any – have been culled to date.

However, members of a local brumby preservation group claim more than 30 carcasses have been found hidden in the Barmah National Park, with fears there may be more.

Parks Victoria have also refused to confirm whether they are behind these deaths.

Yet governmental tender documents have revealed that contractors who are employed by the government to exterminate the brumbies are required to move carcasses to hide their controversial work from public view.

Ms McLeish said that brumbies are an iconic part of Victorian High Country and of our state's cultural identity.

"While maintaining biodiversity in Victoria's parks is necessary, any management of brumby populations must be conducted ethically and sustainably," she said.
