Victoria must address deer danger: expert

As Victoria's feral deer population reaches an estimated one million and the animals venture onto busy roads, there are calls for government intervention.

Victoria's roads and highways could more regularly become the stalking ground of feral deer as numbers of the animal skyrocket, the state's parks association warns.

A motorist recently captured footage of a deer darting between vehicles on a busy Melbourne freeway and Phil Ingamells from the Victorian National Parks Association estimates there's a feral population of about one million.

The Victorian government should urgently come up with a well-funded, strategic control and containment plan before the feral deer destroy "vulnerable native ecosystems, farms and people's safety", Mr Ingamells said.
