What can the world tell us about reopening?

With nearly 52 per cent of Australians over 16 years now fully vaccinated, there is more and more talk about opening up once it's safe.

But there are other parts of the world that are a bit ahead of us, opening up and removing all restrictions.

The UK removed restrictions in July, Denmark ended COVID restrictions two weeks ago, and Norway removed restrictions over the weekend.

So on today's Coronacast, what can we learn from those countries on our own path to eventually reopening?

Also on today's show:

* Is there any risk of catching the virus from swimming pool water?
