Cyclone Debbie has caused extensive damage to cane fields, live stock and fruit and vegetable farms in north Queensland with the damage bill expected to be in the hundreds of millions of dollars.
Queensland Farmers' Federation (QFF) president Stuart Armitage said while the cyclonic winds have passed, torrential rain has water-logged some fields.
"Although it is early days, the region is worth over $1 billion to Queensland's agricultural production value so it would be fair to assume that the damage will be at least hundreds of millions of dollars," Mr Armitage said.
"As the system moves inland and southward the expected high rainfall will most likely result in flooding in regions that were not initially impacted by the cyclone."
He said early reports point to extensive damage to sugar cane, fruit, vegetable, foliage and animal producers.
Floodwaters and bad phone reception have isolated some farmers.
"It is essential that farmers continue to monitor their local situations as flood warnings have been issued for coastal catchments between Gladstone in Queensland and Bellingen in northern NSW," Mr Armitage said.
