Sounds good, and easy to roll out.

Without looking at the app in detail, I wonder how they get around the problem that Person X, supposed to be in quarantine, goes out, leaving their phone at home where person Y will take a photo of a previous photo of Person X that has been printed out.

interesting point Frank. Not sure of the answer however this app is already working in WA for local quarantine situations. IdeaSpies has suggested a trial of this idea and/or the electronic bracelet idea from Israel for interstate and international travellers.

We need to find a way to help more people come to Australia and people here to go overseas and return. It's not fair to separate families for years as well as continue the economic damage to our society. Any more ideas appreciated.

Note that this idea is point 2 on the IdeaSpies Positive Pandemic Plan
