The Landsborough Highway between Barcaldine and Winton was closed on Wednesday afternoon as rivers began rising across western Queensland in the wake of the downpour brought by ex-tropical cyclone Trevor this week.
There are currently major flood warnings for the Georgina River, the Thomson River and Cooper Creek, and moderate flood warnings for the Barcoo River and the Cloncurry River.
The Bureau of Meteorology has issued minor flood warnings for the Bulloo River and the Western River, a flood warning for the Diamantina River, and flood watches for the Warrego and Maranoa region, as well as an initial minor flood warning for the Bohle River.
Longreach district police inspector Julia Cook said the Landsborough Highway had been closed between Barcaldine and Winton on Wednesday afternoon, with water over the road in multiple locations.
"There are lots of other closures on minor roads - this is a widespread event," Ms Cook said.
She emphasised that just because people were familiar with an area and may have lived somewhere all their life didn't mean they were not in danger when creeks were rising and roads were slippery.
"We can't emphasise often enough, if it's flooded, forget it," she said. "It's just not worth it."

Ms Cook said at this point the closures would only be shortlived, unlike the 12-day road closures in north west Queensland in early February.
