Australians in London, India and South Africa will be given access to charter flights to come home under a deal finalised by the federal and Northern Territory governments.
The decision will give roughly an extra 5,000 people currently stuck overseas the chance to come home between now and March next year, and quarantine in the Howard Springs facility, 25 kilometres south of Darwin.
But there are still a few things that aren't clear about the deal.
What we know
As well as knowing where the flights will come from, we know who's first in line: "vulnerable" Australians in the United Kingdom.
"It is a broad spectrum of circumstances that could place someone in a vulnerable position," Prime Minister Scott Morrison said.
He said the Department of Foreign Affairs and Trade (DFAT) makes "bespoke decisions" on each different case.
Qantas will be providing the flights and have the priority list of vulnerable passengers, who the High Commission in London is now contacting.
"The good news is of the around about just over 4,000 Australians who are identified and DFAT identified as vulnerable on 18 September, just over a quarter of those have now been able to return to Australia," the Prime Minister said.
That means there would be room for around 2,000 people not classified as vulnerable to fly home.
The first two flights will leave London on October 22 and New Delhi on October 26, carrying 175 passengers each.
When people arrive at the airport there will be a "traffic light system" to make sure people entering from overseas are kept separate from other arrivals.
As for travel from other countries, Mr Morrison said: "We're very, very many months off that."
People entering Howard Springs will have to pay for their quarantine, which costs $2,500 for individuals and $5,000 for families.
Mr Morrison said the agreement is until March 2021 but could be extended or the arrangements at the facility extended again if possible before then.
He also said not all flights would "necessarily" go to Darwin.
What we don't know
We don't know which other facilities returned passengers will quarantine in.
The Prime Minister also didn't say how much the flights would cost people only that they will "be available at commercial rates to passengers" and DFAT will provide loans to those who need it.
The ABC understands it'll be around $2,000 for the flights from the UK and a little less from India.
Speaking of cost, we also still don't know much this deal is costing the Federal Government.
It's not just the dollar figure either, the plan is going to require a lot more doctors, nurses and staff to man the facility but there's no clarity either around how many will be needed, where they'll be hired from or when.
