The Bureau of Meteorology (BOM) says a cyclone could form off north Queensland early next week but is unlikely to cross the coast.
BOM forecaster Doug Fraser says a low pressure system in the Coral Sea will probably develop into a cyclone on Monday or Tuesday.
"The good news is all the models are taking that further away from the coastline so not expecting to see any direct effect on the coastline," Mr Fraser said.
"But [there is] quite a fair chance of seeing that cyclone development into the beginning of next week."
