Australia has indicated it is on track to restart repatriation flights from India where thousands of people are stranded under a controversial travel ban.
But the 9000 citizens and permanent residents who want to return home could be forced to wait months to board a plane because of the nation's quarantine capacity.
Prime Minister Scott Morrison is adamant the pause has worked to ease the pressure on the quarantine centre at Howard Springs in the NT.
"The early evidence indicates that that temporary pause to the 15th of May is on track," he told reporters in Melbourne on Thursday.
"We are very hopeful and confident that on the other side of 15th of May we will be able to start restoring those repatriation flights."
Cabinet's national security committee convened on Thursday ahead of Mr Morrison chairing a meeting of state and territory leaders on Friday.
While the number of vulnerable Australians in India has soared from 600 to 900, the prime minister said no one required medical evacuation.
The federal government is facing a legal challenge to the travel ban, with lawyers arguing the restrictions are unconstitutional.
Mr Morrison shrugged off concerns from human rights groups about the pause but refused to be drawn on the legal action while it is before the courts.
The prime minister insists there is almost no chance harsh fines and jail time will be imposed on anyone who tries to return from India.
But that has not satisfied Gary Newman, 73, who has been stuck in India for more than a year and has launched court action against the ban.
The Federal Court will hear the case on Monday.
Immigration Minister Alex Hawke is not committing to a timeline for stranded and vulnerable Australians to find a way out of India.
"There is no way we can work through the Indian system immediately to remove every person, if indeed they wanted to go - it will take some time," he told ABC radio.
Australia's medicines regulator has reported a total of 11 blood clots from more than 1.2 million doses of the AstraZeneca vaccine, in line with rates seen overseas.
Therapeutic Goods Administration boss John Skerritt said the five newest cases were in people over 50 because the jabs were largely restricted to that age group.
"The benefits of this vaccine for the over 50s still very significantly exceeds the risks of this vaccine," he told reporters in Canberra.
One person has died while four of the five hospitalised have returned home.
More than 2.4 million doses of coronavirus vaccines have been administered with 77,215 jabs in the past 24 hours.
