A FIRE burning near homes on Queensland's North Stradbroke Island is under control but residents must be ready to evacuate.

Local Queensland Fire and Rescue Service area commander Rob Boniwell said rain today had helped slow the blaze, which is burning in inaccessible land 2km south of Amity Point.

"Now it's just picking up again but it is under control by fire crews at the moment," he told ABC radio.

He said the fire is burning on the leeward side of the island so is largely unaffected by the strengthening winds.

Mr Boniwell said if Amity Point residents have a bushfire survival plan they should review it and be prepared to act.

The QFRS will be putting out further messages later today and tomorrow.

"Basically listen to your local radio, listen to your local media, and just be prepared so in the event they do have to move and be relocated then we can do so effectively," he said.

The blaze has been testing firefighters since Sunday, when it destroyed four caravans, a large shed, a demountable house and cars at Myora on the island.
