Some of the people are people of NSW returning from Victoria.
What we should have is a copy of the COVID 19 with the negative result date less then 3 days before travel, a team of police in Melbourne to check for the reason and collect the details of individual including the address of the place that they are staying.
To track if the people are staying at home, surely there is a programm off the shelf that people can download and their location is tracked to ensure they are in self isolation
