The State Government announced on Sunday brush-tailed rock wallabies were chosen to feature on registration labels after a public vote.

The competition received more than 2050 votes from people selecting from four threatened species - the brush-tailed rock wallaby, the eastern barred bandicoot, the Baw Baw frog and the purple diuris orchard.

Parks Victoria brush-tailed rock wallaby project officer Tony Corrigan said he had encouraged many people to vote for the brush- tailed rock wallaby.

"I reckon I was responsible for a lot of those votes," he said.

"It's a pretty easy animal to sell.

"It certainly helped with raising the profile of the red-tailed black cockatoo in 2006."

Mr Corrigan said Parks Victoria was planning to release 10 brush-tailed rock wallabies into the Grampians in three months in the hope of reintroducing the species to the area.

They have been extinct in the Grampians since 1998.

"It is excellent timing, it will coincide with when the registration labels are coming out," he said.

Mr Corrigan welcomed people wanting to help out with the project.

"We're still looking for volunteers to help with getting the site ready and monitoring the animals post-release," he said.

"We're also still looking for corporate sponsors."

Mr Corrigan said people interested in helping could call him on 5361 4021.
