Hi Mary-Louise, is there any data on whether this worked at the start of Victoria's second wave? People can drive around the roadblocks. My partner had to visit her grandma for care responsibilities in a locked down suburb and we saw the police ahead so just took the backroads.

Makes lots of sense.
