"We've had 18 months of black stubble and only 9mm of rain (total)," Boulia Shire Mayor Rick Britton said.

"But now we have had 12 inches (300mm) of rain and it looks like we have more to come in the next week."

Cr Britton said everyone in the Boulia township and outlying stations and communities was relaxed, despite the fact most of the floodways into the town were under water.

"Our shopkeeper has been doing his job for about 40 years and hopefully we will not run out of things like milk, fresh vegetables and bread," he said.

"We've got the Mt-Isa-Boulia road open and most of our supplies come down there anyway."

The status of the roads around Mt Isa remains variable, as supplies are delivered intermittently.

The Bureau of Meteorology said the region would see rain and scattered thunderstorms with some moderate falls NW of Boulia to Cardwell today.

Meanwhile, the residents of the east coast of far north Queensland continue to count the cost of floods that hit this week.

The Bureau of Meteorology said the king tides that had contributed to the recent flooding in Cairns and Townsville in far north Queensland had now abated.

Flood warnings are still current for the Diamantina, Georgina, Nicholson, Gregory, Cloncurry, Flinders and Norman Rivers and Eyre Creek.
