Troo Believer,
I sympathise with you as your obviously international, but the whole system is just an unmitigated disaster even for a domestic pilot like me.
Ive put up with 1 year of this crap state by state disaster system that changes daily, gone through seven 2 week quarantine directions, now up to 36 COVID tests and ridiculous and completely inept rules that are all based on land based people, not pilots or cabin crew going through most States weekly. The best I had was arriving into SA after doing simulator in Melbourne during the height of their lockdown last year. SA police asked, have you had a COVID test in the last 7 days? , Me , yeah 6 days ago in QLD before I went to VIC for simulator. SA police officer, right! Your good to go! Lol...The whole thing is a joke and I can only imagine the shambles that would involve international flights, it would be double layered crap.
