A handful of rescue flights from India are set to be organised as officials bolster infections controls at the Northern Territory's quarantine facility to prepare for their arrival.
The ban on flights from India will end on May 15.
The first repatriation flights to Darwin will arrive on May 15, 23, and 31 - where people will be taken to the Howard Springs facility.
Another three flights are being looked at to land in other states.
Queensland, Victoria and NSW have agreed to accept flights, while South Australia is weighing it up.
Up to 200 people could be on each flight.
Howard Springs can currently accept 850 people per fortnight, with capacity being increased to 2000.
Department of Health senior official Caroline Edwards said work was being done to ensure the facility could handle more positive cases of coronavirus.
About 50 positive cases can now be at the facility.
The number of people with coronavirus at Howard Springs has fallen to 21 from more than 50 a week ago.
The government argued its flight ban was necessary to ease pressure on quarantine and prevent a third wave breaking out in Australia.
India's health ministry has reported 414,188 new cases of coronavirus in the last 24-hour reporting period, another one-day record, with 3915 people dying.
Chief Medical Officer Paul Kelly said there had been 137 cases of the virus from people returning from India in the past month.
"We are in a very off-the-chart situation now than what we designed the quarantine facilities (for)," he said.
The facility had been set up for quarantine with a two per cent positive case rate.
NT acting chief health officer Charles Payne is expecting a 10 per cent infection rate among the passengers repatriated on flights from India.
"We have now negotiated and agreed to a number of measures that will reduce the number of positives coming through and we are satisfied that we can manage that," he said.
If virus patients need to be hospitalised, Ms Edwards said arrangements would be sought for them to be transferred to their home state for treatment.
The Royal Darwin Hospital can only handle three to four positive cases.
"We are very concerned about the vulnerability of the Northern Territory health system and the surrounding populations, and so working closely with them," Ms Edwards said.
There are 9500 Australians in India who want to return home, with 950 of them considered vulnerable.
Professor Kelly said the numbers fluctuated so he could not outline a timeframe for everyone to return.
"I cannot put a promise out there that we will get everyone home from India, nor a timeline for that, because how long is a piece of string," he said.
The pause on commercial flights out of India will be reviewed next week.
