After plunging the state into a full lockdown, then dramatically performing a massive U turn a few days later, South Australia is hoping its outbreak is under control.

It's been a week since health authorities discovered coronavirus had somehow broken out of hotel quarantine and had infected nearly 20 people.

Since then, 4500 people are in quarantine and the number of cases has slowed - despite claims that the state was dealing with a particularly fast moving virus.

So has South Australia managed to control it? Are they out of the woods?
