ACT Chief Minister Andrew Barr says Canberra is ready for travel bubbles with South Australia, Tasmania

Mr Barr said he was working with his Tasmanian and South Australian counterparts to open a travel bubble among the jurisdictions which have so far stamped out coronavirus outbreaks.

South Australian Premier Steven Marshall said on Thursday, the committee responsible for easing COVID-19 restrictions in the state would discuss an ACT travel bubble on Friday, but couldn't say if it would be given the green light.

"The ACT has done extraordinarily well," he said.

"The big decision is whether we can separate out the ACT from NSW."

He said border restrictions would be lifted as early as possible and praised NSW for staying abreast of growing case numbers.

"NSW continues to do well and I know some people look at the daily total and think ... this is going up, but you've really got to unpack those numbers, alot of those numbers are of no consequence whatsoever, we know the link or they are in hotel quarantine," Mr Marshall said.

"What is of concern to us is if there is local transmission without a link, and there were some cases of that in NSW today and yesterday."

"But what we often find is a day or two days later we can trace that link back."

Hopes of a Canberra to Adelaide travel bubble were revived on Wednesday when ACT Liberal senator Zed Seselja said that after speaking with South Australian Premier Steven Marshall, he was optimistic restrictions on Canberrans travelling into the state would be eased soon.

Canberra Airport has welcomed the idea which would be an small step towards restarting tourism.

The airport had approached South Australian and Queensland governments about a travel bubble in July.

"We believe from a health perspective this is a manageable risk as it's been almost two months since the ACT recorded a new COVID-19 case and South Australia has had very low levels of infection," head of aviation Michael Thomson said.

"It's in all our best interest to take such a step to show it can be done both between ACT and South Australia and also between ACT and other states.

"There is significant demand for flights from business in ACT and South Australia, and there is also significant tourism demand and a strong desire to visit friends and relatives in our two regions.

"It's time to open the borders and get back to flying."

Mr Barr said a travel bubble with Tasmania was also on the cards with a proposal to airlines and airports in the works.

"I've been in discussions with the SA premier, Tasmanian premier and our Queensland colleagues," Mr Barr said.

"I'd say that South Australia is the most advanced in its planning and thinking, in relation to safe cities pairs.

"We've been working with the Tasmanian government, our respective tourism authorities and our respective airports, around a package of support for airlines to operate between Canberra and Hobart.

"One practical way we can address that is initial flights could be ACT residents only. There would be an identity check through Canberra Airport and then a check on arrival in the state or territory that you're flying to."

Border issues will be on the agenda for Friday's national cabinet meeting as the federal government call for a national definition of a COVID-19 hotspot.

The ACT, which will mark two months without a new infection on Friday, has been declared a hotspot by the Queensland government, which closed its borders to Canberrans after one person used the capital as a backdoor to the sunshine state.

On Thursday, Mr Barr said Queensland Premier Annastacia Palaszckuk had been too harsh on the ACT.

"The one example was disappointing and it was a gap in the system we needed to address," he said.
