A koala that escaped flames that destroyed 60 per cent of North Stradbroke Island has been mauled to death by domestic dogs, wildlife rescuers say.

The animal's death has prompted a reminder from Redland City Council to pet owners to ensure dogs are secured in yards or on leashes, with native fauna vulnerable to attack following the destruction of their homes.

Councillor Craig Ogilvie, whose ward takes in North Stradbroke, said dog attacks were a common problem on the island.

In the wake of the fire however, he said it was even more critical that domestic pet owners not let their animals roam free.
