Australia Covid live update: Victoria premier Dan Andrews eases lockdown after 10 new cases; Gladys Berejiklian confirms 172 local cases in NSW

Campsie, there is a community where we had a lot of cases and sometimes it’s difficult to tease out, you know what the source of the infection was versus where people are just travelling when they’re infectious, but over time it was clear that the number of cases had visited the shopping centre there and there was transmission identified a number of shops.

So as a supermarket worker that [visits] numerous shops in this shopping mall in a situation where we’ve got numerous cases in the community and you know how many people were exposed as a result of those positive cases in that shopping tonight I don’t have the exact number but it’d be many, many people in the community.

So what we do is we interview cases we identified where they’ve been in that, that period, and then inevitably when somebody is exposed. That takes some days to get sick, and then we interview them, and there’s always a period between their exposure and identifying publicly and us understanding where they might have acquired.
