The owner of Adelaide's Governor Hindmarsh Hotel, Brian Tonkin, said the well-known music venue and business could only survive another four months financially.

With restrictions on gatherings and travel seemingly not easing anytime soon, he said the venue's future hung in the balance.

"We've received no assistance whatsoever into surviving as a business. We haven't received a brass razoo," he told ABC Radio Adelaide.

He said the venue was run as a low-profit business, yet all workers were eligible to be paid under the Federal Government's JobKeeper program, so they could survive.

"But the jobs aren't going to be available to them when all this is over," he said.

As one of Adelaide's top local music venues, it has also hosted some of the biggest Australian and international acts.

Australian bands Wolfmother and Polaris played at the venue earlier this year and UK rock outfit The Darkness also visited to play a gig in March, right before restrictions were put in place.

American band Jimmy Eat World were forced to cancel their show at the venue scheduled for later in March.

Other acts scheduled to play at the venue this year included Baby Animals, Killing Heidi, The Whitlams, Spacey Jane, James Reyne, The Rubens, Thelma Plum and Boy & Bear.

Mr Tonkin said the venue had supported the Australian music scene for years, however, with flights halted it was looking like music gigs could be held off for a while yet.

"We support lots of South Australian music, but the problem is we use lots of international and interstate music … it's probably going to be 9-12 months before international flights are going again," he said.

"I think the Gov isn't going to be worth the real estate it's built on … I'm only representative of a lot of small businesses in this situation."

Second flight arrives with stranded Australians

Earlier today, a second flight carrying hundreds of passengers who had been stuck overseas because of the coronavirus pandemic arrived at Adelaide Airport.

The charter flight carrying around 300 repatriated Australians had travelled from Mumbai, via Indonesia, with passengers taken to an Adelaide hotel for quarantine.

Premier Steven Marshall thanked police and other services for the way they managed the arrival of hundreds of Australians on board the first flight, which touched down yesterday morning from India via Denpasar.

Today's passengers will be in quarantine at the Playford Hotel in Adelaide's CBD for two weeks, the hotel will be under police guard 24/7 to ensure no-one leaves the premises.

The operation is also being closely monitored by health authorities in an attempt to prevent any possible outbreak.

Premier Steven Marshall said on Saturday the flights were part of a coordinated effort with other states and territories.

"All operational measures have been put in place to enforce the returning citizens' 14-day quarantine period and ultimately keep South Australia safe and strong," he said.

"We can't leave Australians stranded."

Students will need to apply to receive a payment of up to $1,000, with Trade Minister David Ridgway saying the students needed the support.

"We're hoping that this will be enough to get the students through until we're out the other end of the circumstances that we're facing at the moment," he said.

"They're a very important part of our community and we want to make sure that they're safe, they're secure and they continue to study."

He said international students had brought in almost $2 billion to South Australia last year.

"It's a very important part of our economy, very important part of our community," he said.

"They add such diversity to our cultural experience in South Australia but also underpin a lot of very important economic activity."

Restrictions to be relaxed at aged care homes

Some coronavirus restrictions on aged care homes are being relaxed. They had been closed to visitors for some time.

People visiting residents for "end of life" support and essential visits by doctors and medical staff are exempt from the requirement that they have spent 14 days in quarantine.

The new direction came into effect this morning, however, interstate visitors are still expected to be in quarantine when not visiting a facility.

SA Health today confirmed two additional cases in the state in the past 24 hours, with the total now sitting at 437.

There has now been 376 recoveries, which is 86 per cent of the state's total cases.

It comes after three consecutive days with no new coronavirus cases in the state.

Health authorities have now called for more South Australians in the 21-to-30-year-old age group to present for testing, so they can identify any asymptomatic carriers of the virus.
