At least 7,000 people are still without power in South-East Queensland as devastated families begin the cleanup from extreme weather which saw an entire summer's worth of rainfall in some regions since Christmas.
An easing in the rainfall should see floodwaters start to steady and recede from Wednesday.
50 Australian Defence Force members have green-lit to assist with the recovery effort and will have their boots on the ground by Thursday.
On Tuesday, 88 SES Victoria and 42 SES New South Wales joined 170 members of Queensland's SES in disaster recovery.
700 Energex crew members are working out in the field to restore power by Friday.
But residents are skeptical power will be restored before the weekend.
