I don't think an Australian citizen should be denied entry back into Australia.

Maybe they should create a bubble whereby all ppl providing services to turned travellers are also in the bubble.

But like fly in fly out workers

Cleaners, healthcare workers, police, adf who are rostered works abd isolates in the bubble for say 3 weeks. Then they have 2 weeks off in the bubble and tested. Then they have how many weeks off outside the bubble before coming back in.

They should get paid well as well.
