Shame that they hadn't been more vigilant before school holidays started, and when it became first known that the quarantine issues were awful. Vic families travelling have likely spread the joy around in the last week. It was posted here multiple times weeks ago that this was a risk time and that may have come home to roost.
One last hope is that the demographic travelling to/holidaying in regional areas is different to the demographic which has seen the biggest problem with the spread of the virus. A small hope anyway.
