I don't think it's an "if" as to whether we'll be based in Aussie again. There will be no travel bubble again, not in the next 12 months anyway.
Maybe exemptions for international vaccinated travellers like sports teams who fly, bus, hotel, play sport/do business, hotel, bus and fly home.
Vaccinated NZ/Aus citizens who MIQ for only 5 days, or quarantine at home for 5-14 days (with officials dropping in to check) instead of MIQ.
