A humanitarian flight carrying evacuees from Afghanistan has arrived in Darwin, where they will spend the next two weeks quarantining at Howard Springs.

The Qantas plane touched down shortly before 4:00pm [ACST] after travelling from the Al Minhad Air Base in Dubai, which is used by the Australian Defence Force as a logistics hub.

Australian forces evacuated around 4,100 people from Afghanistan after the Taliban seized control of the country.

Over recent days, hundreds of those evacuees have been flown to other Australian cities.

The Department of Foreign Affairs and Trade would not provide the ABC with any details about today's flight to Darwin, including the number of people on board.

But Northern Territory Chief Minister Michael Gunner confirmed the plane was carrying people from Afghanistan who would be cared for at Howard Springs.

"The Territory will be a place of refuge for these people for the next 14 days while they quarantine at the Centre for National Resilience," Mr Gunner said.

"Many of these people fled with no personal possessions.

"We will make sure they are provided with fresh clothing and other items and ensure their stay in the Territory is a comfortable one.

"We have nothing but empathy for the people of Afghanistan."

The Save The Children charity said it had been engaged by the NT government to provide support to Afghan families staying at the facility.

"We've provided about 200 support packs so far," the charity's director of international programs, Mat Tinkler, said.

"And these are things from the very basics like clothes — a lot of people fled with literally just the clothes on their back."

He said the support packs also included hygiene kits for women and toys and games for children.

"We know that kids have been through enormous trauma in situations like this," Mr Tinkler said.

"So it's critical that as soon as possible we bring them a sense of normality and routine and start to engage them in sensory activities with toys.

"And that's a really important part of their recovery and integration into the Australian way of life."

Earlier today, federal Home Affairs Minister Karen Andrews said unaccompanied children were among the recent Afghan arrivals in Australia.

"We all witnessed the scenes in Afghanistan where … adults were passing their children through the gates," Ms Andrews said.

"There are some unaccompanied minors here in Australia at the moment who are being well cared for."

She said the number of children without their parents was currently less than 10, but she said more would be arriving in the coming days.
