Yep, the Pacific Ocean does make a reasonable moat, but given the credulity of the previous US administration, I then questioned whether it was adequate.
Down here in Tasmania we have also raised the drawbridge and effectively closed Bass Strait, locking out
"all those contaminated people from Sydney and Melbourne". Drastic, but it seems to be working. We have only had one covid case this calendar year. And restrictions here are relatively minor:
- sign into any commercial premises (for tracing purposes),
- hand sanitisation,
- maintain social distancing - 1.5 metres,
- wear masks when visiting hospitals,
- that's it.
But we know other restrictions will be instantly rolled out if or when we have an outbreak.
