Residents on North Stradbroke Island, off Brisbane, face an anxious night as strong winds drive a bushfire towards dozens of homes.

A watch and act message remains in place for people at Myora Springs and Gatumba Street where residents have been told to enact their bushfire plans.

The Queensland Fire and Emergency Services (QFES) is advising residents that a fire near Brown Lake is heading their way.

QFES says the fire is being fanned by 35 to 55km/h south-easterly winds.

The wind direction is expected to stay the same overnight.

Water-bombing helicopters rejoined the bushfire battle earlier today and an evacuation centre at Dunwich has reopened.

QFES Superintendent Jeff King says the fire is moving in a northerly direction towards the Myora and Myora Springs area.

"We just want to make sure that we get the heat out of it and slow it down a bit before it does reach our containment lines," he said.

"We need the community to be alert, not alarmed, and to keep listening to the radio and follow the Facebook site to get the latest information."

At least 50 firefighters are battling the blaze in difficult conditions.

Dozens of homes have been evacuated, with spot fires also posing a danger.

Residents are being strongly advised to be prepared to relocate to a safer area if required.
