Mackay Sugar says heavy rainfall is causing significant delays to the harvesting season.
At a time when the crush should be well underway, parts of the region have received up to 100 millimetres of rain in the past 24 hours.
CEO Quinton Hildebrand says the delayed start to this year's crush and the unseasonable rainfall will have long-term implications for the mill and growers.
"We do chew through more of the gas which we like to store to run our boilers in the off-season," he said.
"The other impact is if you're not crushing, you're not making sugar, if you're not making sugar there are delays to the flow of proceeds."
Giru grower Marelene Parison says growers had begun burning their cane in preparation for harvest early this week.
However, she says many crops are now too wet for harvest, which will affect the industry.
"Well apart from the growers, it's the haul out drivers ... they're dependent on it for their weekly income virtually, so it really impacts on everybody," she said.
"The cane may be left in the paddock, after so many days, maybe five, probably five days it won't be acceptable to the mill and it depends when the time comes and it's a matter of whether the mill gets enough cane around the district, because I think it's been pretty widespread this rain, so that they can start up."
