As has also been discussed extensively, it looks like WA will be holding onto a few restrictions for travellers, with no indication they are temporary measures:
- Full vaccinations as a condition for interstate travel (international unvaxxed must quarantine)
- Negative tests both 72hrs before entry and 48hrs after entry
- Must complete a G2G pass
- Must use SafeWA for checkins at public venues (though I note compliance with this is low already)
Unclear if you are expected to isolate until that first result is released, but that was certainly the case when I got in from Melbourne just before the border shut in June.
