An emergency was declared for Inglewood, in the Goondiwindi local government area, in the Darling Downs close to the NSW border on Tuesday night.
Residents were told to head to an assembly point at Inglewood Cemetery ahead of widespread flooding expected on Wednesday.
"Significant flooding is expected to occur across the township in coming hours," police said.
Queensland Fire and Emergency Services Assistant Commissioner Stephen Smith said about 950 people had been moved to safety.
"Our crews were working through the night assisting that operation," he told Nine Network on Wednesday.
Mr Smith noted there had been widespread flooding across central Queensland, the northern parts of the state and through the southeast and southwest.
"Overnight there were areas that got up to 180mm of rain," he said.
With the Bureau of Meteorology predicting more wet weather in the coming days, Premier Annastacia Palaszczuk has warned Queenslanders to get ready for the storm season that has come early this year.
"The central and north coast regions were the worst-affected areas, with a small number of requests in the Brisbane, southeast and southwest regions (in the past 24 hours)," she told parliament on Tuesday.
"With catchments swollen due to recent rainfall, this means that localised flash flooding will remain a threat throughout Queensland over the next week.
"I encourage all Queenslanders to prepare for storm season now."
