As the number of COVID cases continues to drop in Australia, there's suddenly a whole lot more talk again about travel bubbles and increasing international arrivals from "safe" coronavirus countries.

The Prime Minister Scott Morrison is talking up an idea to let travellers from countries where there are low caseloads do their 14 days quarantine at home rather than in a hotel.

While mismanagement of the hotel quarantine system in Victoria led to a large outbreak, in other states and territories it has protected the country.

So how could we safely reopen international borders?
