Authorities in Condamine, on southern Queensland's Western Downs, say they are hopeful the river will not get any higher than its current level.
The Condamine River is steady at 10.35 metres, well short of the 11.7-metre peak predicted earlier this week.
Western Downs Mayor Ray Brown says the gauge upstream is falling but the river should remain high for a while.
"It's been very stationary and that's the issue," he said.
"It's such a big river that it's just stayed at a very stationary height.
"Still a huge concern - it's a major flood.
"It's frustrating we just can't get across that bridge because the bridge height's 10.1 but we've got a lot of debris on the bridge which means which means our staff have to get in there safely to remove that debris."
Meanwhile, the floods have had a big impact on Condamine businesses, according to one local operator.
Local publican Shane Hickey says floodwaters have prevented traffic flow through the town.
"All our contractors, especially [the ones] that normally inhabit the hotel and motel, they can't come through," he said.
"So it impacts on the motel - the motel at the moment is zero.
"So there's nobody in the motel and we're normally running at 80 or 90 per cent occupancy most of the year.
"For us it's huge, it's probably 60 or 70 per cent down on a normal week."
