Dogs could be banned from some south-east Queensland suburbs in a bid to protect at-risk koalas.

A brains-trust of koala experts - University of Queensland's Associate Professor Jonathan Rhodes, Central Queensland's Dr Alistair Melzer and Dreamworld's Al Mucci - comprise a panel to advise on last-ditch efforts to stop koala extinction in Redlands, Pine Rivers and other areas, following a directive from Environment Minister Steven Miles on Monday.

Dogs could be banned from some south-east Queensland suburbs in a bid to protect at-risk koalas.

Panel chairman Associate Professor Rhodes said it was clear policies to "protect habitat" by themselves simply did not work.

"There could be things like that, or it could be active management of the threat from the dogs, if they are domestic dogs or wild dogs. And the threats and their responses to those threats are quite different," he said.
