We recently travelled to Canberra to visit our younger daughter and her family and as a result of that we were required, as part of the COVID restrictions, to apply for a permit to return home. You need a permit to enter Victoria to let the authorities know if you have been in one of the various traffic light zones. There are red, orange and green zones, depending on the amount of infections in the various areas.
We had been in Canberra, it is a green zone, so there was no difficulty in reentering the state and quarantine was not required.
I have deleted all the personal information.
Unfortunately it looks as though our present lockdown is likely to be extended.
