Marianne McCarthy's station in outback south-west Queensland is going to be cut off by floodwaters for the next two months — and she wouldn't have it any other way.

The school teacher and station manager lives with her family at Bulloo Downs homestead at the southern end of the Bulloo River, about 120 kilometres south-west of Thargomindah.

The area has received record-breaking rainfall and residents have become stranded on remote station homesteads transformed into inland islands.

Ms McCarthy said being prepared for isolation is all part of life in the outback.

"It's been pretty heavenly other than the sand flies and mosquitoes," she said.

"It's a pleasant change from dust storms and no water.

"It's just such a relaxed atmosphere, I think it's the relief of rain and feed for cattle."

Ms McCarthy said planning ahead was the key.

"You learn to always be stocked up and be prepared," she said.

"This time we just ducked across to Broken Hill — a seven-hour trip — and grabbed a Toyota load of stores and made sure we had meat in the freezer.

"Then you can just sit it out and not have to worry too much about anything."

Ms McCarthy said trying to get her three children to focus on school work during the flood was the most stressful task.

"When there's rain and flooding and outside interest they're not really easy to keep in here," she said.

"We've got a pretty good routine, but I suppose you get a bit lenient when all this is happening — it's pretty boring for them most of the time.

"Every day we finish school all they want to do is go down swimming.

"They are beside themselves at the moment, I think their biggest concern is how the Easter bunny is going to get here."

Ms McCarthy says keeping her children entertained when cut off can be challenging. ( Supplied: Marianne McCarthy )

Post delayed for weeks

Janet Anthea Beetson is the local postmistress in Thargomindah and received her first load of mail in more than a week on Monday night.

Ms Beetson said she was concerned the post would be delayed for weeks.

"A lot of people rely on the mail," she said.

"The only way to get mail out here basically is by road transport, they don't allow it on the plane.

"It's very, very important — not just for grocery lines and your letters and bills … people get medication through the mail.

"Easter is coming up and people get a lot of stuff from away and that's a bit a sad."

Ms Beetson said she was optimistic tourists would flock to the area later this year, once the roads open up.

"This beautiful rain that has come along will bring this country alive, I've seen the wildflowers out here just go for miles," she said.

"I hope that people do come out and see this and experience it."
