There have been more flood-related rescues in southern Queensland.

A 68-year-old man has been flown to the Bundaberg Hospital after falling ill on his isolated property at Lowmead, north-west of the city.

John Kennedy from the Action Rescue Helicopter Service says a woman also needed help at Doughboy, south-west of Bundaberg.

"She was on an isolated property and her medications had run out," he said.

"She lived by herself and we were contacted mid-afternoon to see if we could move her from her property back to the township of Gin Gin."
