North Stradbroke Island could soon ban domestic pets in an effort to save its koala population.

The Quandamooka Yoolooburrabee Aboriginal Corporation (QYAC) said unrestrained domestic pets had been responsible for fatal maulings of koalas and kangaroos in recent months.

"Recently we had a male and female koala attacked by domestic dogs and killed in the township," chief executive Cameron Costello said.

"We've also had kangaroos mauled on beaches as well and dogs chasing them through the streets.

"It's not just traditional owners but many local residents who have been dog owners [that] have realised that the two can't co-exist."

Controlling pets 'not an option'

Mr Costello said to save the native animals the local community and tourists alike would need to be supportive of their plans to ban domestic pets.

"We've tried to get people to control their pets before but koalas can climb fences and dogs can get out," he told 612 ABC Brisbane's Spencer Howson.

"With the holiday season fast approaching, we will also see a huge increase in domestic animal numbers on the island.

"Tourists bring dogs and they take them off leash, so compliance isn't working ... we need a long-term solution."

Mr Costello said he would like to see a phasing out process, which would see a slow decrease in the number of pets allowed on the island.

"Current owners would be able to keep their pets till they passed on but they wouldn't be new registrations," he said.

Council to consider change

Mayor of Redland City Karen Williams said she was happy to take the idea to council.

"We need to bring the community on this journey and it will be their behaviour that will make a difference to koalas right across the city," she said.

"I would be encouraging Cameron and the group to gather a petition and I would be more than happy to present that to council."
