This is my main question. I'm in Alice, and fly QFF ASP to DRW, then will exit Australia maybe med next year via DRW - SIN - CDG all direct. Can I land in Darwin, then same day without leaving airport fly bac to Alice and home quarantine? Is there a timeframe between landing and departing domestically - same airport, and will ensure I return and exit same day. Would even be prepared to home quarantine AirBNB in Darwin, but rather flyhome and quarantine at home.
This would be the same in other states, flying into Perth & onflying to Kalgoorlie, Sydney to Orange, Melbourne to Ballarat, you name it.
