South Australia will cap the number of repatriated Australians to be quarantined in local hotels at about 1200.
Police Commissioner Grant Stevens says while SA is working with the rest of the nation to help Aussies come home, the state is mindful of the operational logistics involved.
"We do have a cap in South Australia in terms of the number of people we can accommodate and we won't accept flights if we exceed that cap," he told reporters on Tuesday.
"(We're) looking around a 1200 person cap but that is subject to if they are individuals or families."
There are currently 527 people in supervised quarantine in Adelaide.
With international flights redirected out of Victoria as it deals with its COVID-19 outbreak, the SA opposition called for similar limits to those in Western Australia.
WA Premier Mark McGowan urged flights into Perth be limited to one every three days.
A limit has also been introduced in NSW with only 50 people on each flight, or 450 a day, permitted to land in Sydney.
Mr Stevens said SA did not intend to place any restrictions on the number of flights coming in.
Health Minister Stephen Wade said the state government had a tried and tested procedure in managing returned passengers safely and would not push it beyond sensible limits.
"It is common sense that the state government will not be accepting any flights which we could not manage appropriately," he said.
"South Australia has not received one flight of repatriated Australians diverted from Victoria and to suggest there is some risk we will become overwhelmed is bare-faced fear-mongering."
Opposition health spokesman Chris Picton said SA should not have to "pick up the load" from other states if they chose to cap their numbers.
"SA is already doing its share," he said.
"To continue to provide hotel quarantine at a high standard and safely, we need to manage the number of arrivals into Adelaide."
On Tuesday, almost 50 people arrived on a Singapore Airlines flight and were placed in quarantine.
That came after 120 touched down on a flight from Kuala Lumpur on Saturday
In June more than 250 people arrived from India and about 100 defence force personnel came from Malaysia.
In May about 680 Aussies flew into Adelaide on two separate flights from India.
