Around 150 homes in Logan are underwater today and many residents of the area remain cut off.
Boats have been used to get supplies to those affected by the worst flooding in four decades.
The most affected suburbs are Waterford, Loganholme and Beenleigh.
Floodwaters have also damaged roads, bridges and other infrastructure.
Premier Annastacia Palaszczuk says the cleanup and repair bill could run “into the millions if not hitting the billion mark”.
“I’m sick of these bad times. We’ve had two years of the pandemic, now we’ve had floods across the entire southeast and up to Fraser Coast and I think we need a really good Easter.”
Ms Palaszczuk has been talking with the 1150 people in evacuation centres, many of whom had lost their homes but were relieved to have survived.
She promised the government would help people get back on their feet once the water had fully receded.
“There are so many people that are really going through the toughest of times.”
There has been some criticism of the government for not preemptively releasing water from the Wivenhoe Dam before the intense rain set in.
However, Ms Palaszczuk says that not even the Bureau of Meteorology had predicted that Wivenhoe would be filled with the equivalent of “four Sydney Harbours” in two to three days.
She also says none of the dam releases thus far have pushed the Brisbane River level any higher than the peak it reached from existing flooding.
Meanwhile, the Bureau of Meteorology forecaster Jonathon How has warned of possible severe thunderstorms with intense rain in parts of the region from this afternoon.
“So very much the message to those people in southeast Queensland – the danger isn’t over just yet,”
Commonwealth and state disaster payments of up to $180 per person and up to $900 for a family of five are also on offer for Logan and Scenic Rim residents hit by the floods.
