Firefighters are bracing for heatwave conditions across Queensland's fire zones, sending temperatures and the danger level soaring.
The mercury is expected to reach the mid to high 30s near some of the major fires on Wednesday, while parts of the state's interior are expected to hit 40C.
Queensland Fire and Emergency Services Acting Commissioner Mike Wassing fears the bushfire emergency will push into next year because there is no prospect of significant rain.
The best crews can do is strengthen containment lines and be ready when the weather worsens.
Seventy-four fires are burning across Queensland in the second week of the state's bushfire crisis, which has burnt out 174,000 hectares.
In total, 16 homes have been lost in the recent fires but that figure will rise after firefighters confirmed homes were lost in the Pechey fire north of Toowoomba.
Aerial footage revealed structural damage from the large Pechey blaze, which forced evacuations from the town of Crows Nest on Monday.
"We believe we probably have five structures in there, and maybe more," Queensland Fire and Emergency Services Deputy Commissioner Mark Roche said.
"We've been able to get some aerial footage but we won't know until we get in on the ground ... trees are still burning."
Residents who fled Crows Nest were allowed to return home after an emergency alert was downgraded.
Toowoomba Region Mayor Paul Antonio is fearful of the weather conditions ahead, saying his community is facing dangerous times.
Residents are on water restrictions while work continues to restore power to pumps at the city's main reservoir after it was cut by fire.
Fires of primary concern in the state include the Pechey blaze, a cluster of fires in the Border Ranges region, from Cunninghams Gap to Mount Barney and Mount Lindsay, and one on Moreton Island.
Meanwhile, combined dam levels in southeast Queensland have dropped to their lowest since 2010.
The drop has resulted in the Tugun desalination plant on the Gold Coast being ramped up to full capacity.
SEQ Water is urging residents to start voluntarily conserving water.
It says mandatory restrictions will not be enforced until the combined dam level drops by another 10 per cent, to 50 per cent.
