Rain is continuing to fall in Queensland's north west, with one overnight storm dumping an impressive 65 millimetres at Julia Creek.

Key points: Around 30 cars and trucks were stuck at the Julia Creek roadhouse due to flooding on the Flinders Highway, which is now open, and other local roads

The Flinders Highway has reopened after flooding closed it to all traffic between Julia Creek and Richmond. At one point, up to 30 cars and trucks were stuck at the Julia Creek roadhouse waiting for the road to reopen.

Northern District emergency management coordinator Elliot Dunn said there were plenty of roads cut in the Gulf.

"We expect them [flood levels] to start going down over the weekend and early into next week," Mr Dunn said.

"They're not massive flood levels, so we're not going to see this long-term closure of the Flinders like we have [in the past].

"Moving into next week we are expecting to see more storms up in the Gulf, so we may see more road closures up there."

Much of the region has received soaking rain, with falls recorded for the month of January between 195mm in Mount Isa and 490mm in Normanton, and most of the rain falling over the past week.

Mr Dunn said, despite the road closures, there was no concern that towns would run into issues with lack of supplies.

"Certainly we keep in very close contact with the local governments up in the Gulf, given some of those towns are very small and only have one or two food outlets," he said.

"They've been going really well, you know they stock up prior to the wet season because it's nothing new to them.

"You might not get exactly what you want, but no-one is going to starve."

'The whole town is green' says caravan park manager

Emily Steele from Caloundra has timed the western rain with her position as relief manager at the Julia Creek Caravan Park for three weeks.

The caravan park tipped out 70mm from the past 16 hours (to 8:00am AEST) from the rain gauge.

"I've never been up here before, and my partner is from Holland, so this is all new for us both," Ms Steel said.

"We've only got a few trees fallen down … [but] we've got a lot of rooms to clean in the meantime."

With the east of Julia Creek cut, the caravan park had 16 caravan owners waiting to leave.

"I've never managed a caravan park before … and we're one week in today," Ms Steele said.

"The whole town is green."

'Good to see the cattle happy and healthy' says grazier

Clarafield Station, 100 kilometres south of Julia Creek, had less than in town, only collecting 33mm overnight.

The total was nothing to sneeze at for owner Nigel Simmons, who said the rain was perfect for growing grass.

"Very soaking rain, it hasn't put any water in dams but we run off bores so we don't worry about that," Mr Simmons said.

"Every amount you get it seems to double your grass, so this would be the perfect start to grow a full amount of feed."

In 2019, Clarafield lost its breeding cattle, and is now working with southern-bought Herefords and Angus cross breeds.

Mr Simmons felt anxiety when rain was first predicted but was eased when he saw sunshine above.

"Even yesterday it dried up enough, I went for a ride, and it was just so good to see the cattle happy and healthy," Mr Simmons said.

"[The cattle] were spread out and grazing, not like last year where they were bunched up in corners, knee-deep in mud."

'A favourable start' for barramundi season

Commercial fisherman David Lane said, for those in the gulf, the rainfall has set them up for a good start to the barramundi season.

"So far our totals are around the 492mm for the month so that's looking pretty good," Mr Lane said.

"That's favourable for a start … ideally it'll help keep the box jellyfish away."

Mr Lane said last year the inland flooding pushed a lot of organic material into the gulf river systems, which caused a lot of issues.

"We had a lot of problems with germs and stuff with our crew, hospitalisations for a couple of our crew members," he said.

"This year, with the rain that we've had, having a flush-out would probably be very helpful getting rid of that dead organic material at the bottom of the rivers."

While last year's catch rate was down, demand was staying strong.

"We did manage to survive the season right to the end there, but we were obviously down on catch a lot," Mr Lane said.

"On average I think we were down 30 per cent of our catch rate compared to normally — a big dent in our margins, but we managed to survive.

"The demand was absolutely fantastic for all wild-caught fish, and it still is now."
