NT residents heading home after Trevor

More than 2000 people were evacuated in the NT, the largest such effort since Cyclone Tracy in 1974.

Residents are slowly being returned home after being pulled from the path of ex-tropical cyclone Trevor as it hurtled towards the Northern Territory coast.

It has since weakened to a tropical low and is making its way back to Queensland where forecasters say it will dump heavy rain for a number of days from Monday.

A military plane carrying people evacuated from Angurugu and Umbakumba took off on Sunday morning, and more repatriations are planned for the coming days.

Teams of assessors have swept through and cleared homes in Angurugu, Umbakumba and Ngukurr, but people from Borroloola, Robinson River and Bickerton Island won't be going home just yet.

Officials were being ferried there by helicopter on Sunday afternoon to see just how much damage has been caused.

"This does take a personal toll," Chief Minister Michael Gunner told reporters on Sunday.

"Your homes, your lives, the places you know and care about are threatened."

More than 2000 people were evacuated from communities, the largest such effort in the NT since Cyclone Tracy hit Darwin in 1974.

"We know it was extremely stressful for you in those evacuation centres but you were patient and we thank you for that," Mr Gunner added.

"We are doing everything we can to get you home as soon as possible."

Assistance payments of $503 for adults and anyone over the age of 16 living independently, $250 per child and a maximum package $1266 per family will be made available.

Numbulwar residents in Katherine have been asked to stay at their registered shelter on Sunday night ahead of being bussed home on Monday.

The evacuation centre there was hit by a storm overnight on Saturday, and advice to drink only boiled water remains in place when they get home.

NT police regional controller Travis Wurst said police and vets are checking on the welfare of their pets, along with those in Borroloola, and that there are yet to be reports of livestock losses.

The destructive core of the cyclone passed just southeast of Borroloola and the McArthur River mine, meaning they escaped the most severe impact.

Tennant Creek is also expected to avoid the worst of the storm as it moves through the Barkly region on Sunday, with heavy rainfall expected in the northeast Simpson district.

A flood watch alert was in place for Carpentaria Coastal Rivers, Georgina River, Simpson Desert and the Barkly on Sunday afternoon.

The ex-tropical cyclone is forecast to bring a few days of heavy rainfall to western Queensland south of Mt Isa, starting on Monday.

There is a potential for flooding south of the areas that went underwater last month, but meteorologists are watching closely.

"Those areas could get some rain, and heavy rainfall is hard to rule out at this point," the bureau's Lachlan Stoney said.

"(We are) not necessarily forecasting there to be widespread floods, but flooding would be something that we are monitoring closely for areas south of Mt Isa."
