Australia politics live update: NSW premier Gladys Berejiklian announces 14 new Covid cases; NZ, Qld and Victoria tighten border restrictions

I’ll take you through a recap of the cases over the last day and describes the issues causing us concern.

There were 10 locally acquired cases to 8pm last night. There were three new cases.

The vast majority, yesterday were pleasingly in isolation for the full infectious period.

However, we have had two cases yesterday that were not certain that was the nine-year-old child that attends the Saint Charles Catholic primary school and we have also had a gentleman in his 30s and he attended the birthday party.

In terms of the cases today, we had 13 locally acquired cases recorded after the 8pm cut off last night.

Eight of these cases were linked to the birthday party in West Hoxton, identify the previously reported case, the worker at Bondi Junction.

I’ll describe the sequence of events, so you understand how quickly transmission is occurring, that party and gathering occurred, there were about 30 people there, in a house and the person was infectious at the time, unknowingly, didn’t have symptoms, was unaware, hadn’t attended venues, in that evening, then waited and get tested, when they developed symptoms next day, and we got the result on the Monday.

Immediately, people are asked to isolate and we got the test coming and associated with that.

What you see is that those test results indicate how rapidly the virus was transmitted in the circumstances with 10 cases from that party and that is on day two after the exposure so the event happened on Monday and those individuals were tested on Tuesday, and remember, there is a period where they would not have been infectious. On the Sunday all those individuals would have unknowingly had the infection or periods of Monday.
