Victoria must address deer danger: expert

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.
