Wildlife authorities say koalas are being found in suburban Sydney backyards after being driven from their homes by bushfires and land clearing.
National Parks Association ecologist Dr Grainne Cleary says the the association has received "a few" reports of koalas in western Sydney.
"We're out here looking at one right now," she said from a Campbelltown backyard where a male had taken up residence. "We saw a mum and baby out here yesterday."
The NSW National Parks Association kicked off the first koala census since 2006 yesterday with the assistance of 600 volunteer "citizen scientists".
Cleary says the koalas may be being forced into urban areas by the destruction of their usual habitats.
