More than 8000 stricken homes in south-east Queensland face a tough stretch of days without power as the arduous post-storm recovery begins.
Logan, the Gold Coast hinterland and Scenic Rim areas are worst affected, hit by a heavy one-two weather punch over the Christmas and New Year holidays.
QFES Acting Deputy Commissioner Stephen Smith said "significant impact" had been caused by heavy rains, flash flooding and violent, turbulent winds.

Energex's Danny Donald said more than 8000 homes had no power and that they were "aiming for this weekend" to get people connected again, "either up and running via normal supply or by generation".

"In some areas we're not just making repairs, we're actually reconstructing whole sections of network."
Around 3600 homes in badly-hit Mount Tamborine have no power. Logan is next worst-affected, with 1800 homes still in black out.
The intention is to connect all homes to the grid, but some communities will be running off generational power because of severe infrastructure damage.
"We're not we're not talking one or two power poles, we're talking hundreds and hundreds," Queensland Police Assistant Commissioner Ben Marcus said.
"So it will take quite a long time to restore."

State Disaster Recovery Minister Nikki Boyd said 5090 damage assessments to houses had been completed in south-east Queensland since Christmas, and 17 homes were "totally destroyed".
Boyd said restoration and rebuilding work will gather pace, now the worst of the weather had passed, promising government will ensure "every available set of boots" is on the ground to help.
Financial grants up $900 for individuals and families were available to cover essentials like food, medicine and clothing, she said, urging people to contact community recovery hubs.

"There's still a lot of water in our systems, moving through those creeks, still roads and infrastructure damage through those areas, a lot of hazard out there," he said.
"If you don't need to be out there, please don't … keep access for those restoring essential services."
