Responding to a question in QT today, Morrison said (I'm paraphrasing) "home quarantine is part of the National Plan and will allow fully vaccinated aussies to come home and be able to travel when international borders are open".

I take that to mean that going for a holiday overseas will require a two week home quarantine stay (or worse) upon return. Not sure how many people will be able to stump up 2 weeks at home out of their annual leave in order to enjoy a trip to Bali. Of course, those that can work from home might not be affected. Tough luck if you can't.
