Although the floodwaters were inconveniencing residents, flood affected residents said it was all part and parcel of living in the remote parts of the country.

The Birdsville Hotel manager Kate McDonald said the town's regular supply truck could not get through from Adelaide, but the area was well prepared to be cut off from the outside world.

"This is something that we prepare for anyway, so it's not a big shock. We're coping. We'll be fine as long as the general store here has supplies," she said.

Ms McDonald also said the locals in Birdsville would be happy to sit out the floods because the pub had plenty of beer.

Both Birdsville and Bedourie have had food supplies flown in through Skytrans' regular public transport route.

Diamantina Shire Council chief executive officer Scott Mason said the area was being well looked after.

"We've only had to do one food drop to Carlo Station, north east of Bedourie. We're ascertaining the demand for food and medical supplies from stations and businesses within Diamantina Shire," he said.

Mr Mason said the council was looking into ways to support residents if the floodwaters do not subside soon.

"If the floodwaters stay up we could use helicopters to distribute food and medical supplies," he said.

The Gulf region was also isolated and suffering a shortage of supplies.

The Burketown Hotel acting manager TJ Yanner said the town had not received a supply truck for three weeks.

"The council organised a food drop by plane and that will be coming this week. They will be the first supplies that we've gotten in three weeks," he said.

"There's a lot of water in the river, that's the main problem. We can still drive around town, we just can't go anywhere. It's been raining here for a week and a half pretty consistently in the morning, sometimes all day."

But the town remained optimistic that the floodwaters would begin falling.

"The sky is starting to clear up. Looks like the weather's starting to change," he said.
