A Gympie resident says the council needs to review areas classed as 'flood zones' under its new town plan.
The council made changes to zoning when it released new mapping earlier this year.
The region has flooded five times in two years.
However, local resident Tracy Salter says many properties have been devalued because they have been inaccurately rezoned.
"At no time has water been on the property or even close to the property during these last floods but we found it very difficult to sell because of the flood line and potential buyers were forced to come up with a higher deposit to be able to buy a house that was in a flood zone ... there's a hill, a road and a paddock in between our property and the water," she said.
Gympie council's planning and development committee chairman Ian Petersen says flood zones have been determined according to State Government recommendations.
"I understand people's confusion and I understand their concern but there's nothing council's done that we had any option about - it's just a requirement from the State Government," he said.
"I understand that their properties didn't flood but obviously it's down low and close to flooding."
The State Government says there is no uniform flood level across the state.
It says flood mapping is a matter for individual councils to decide.
