The Dalby Chamber of Commerce and Industry (DCCI) says local businesses fared well during the weekend floods but there will be long-term implications for the southern Queensland town's economy.
More than 230 properties were inundated in the town when Myall Creek peaked at 3.2 metres on Saturday night.
DCCI president Nick Koenig says most local businesses were not affected but the cost to farmers will have a big impact.
"If those farmers only have an average or below average sort of a summer crop - and summer crops are their biggest sort of return - it's going to the retailers and to the local business houses because people just won't spend that money," he said.
"Everyone would like to see some fine, dry weather for a bit and I don't know whether we're going to see much of that.
"Let's just not forget Dalby's principally an agricultural town - I know there's a lot of resource activity happening too but a lot of farmers, their sorghum is ready or nearly ready."
He says as the rain has not gone yet, no-one can say when they might to harvest.
"Then the cotton - it mightn't be as good either," he said.
"I've been talking to a couple of them and nobody's predicting that it's going to be real bumper sort of stuff."
