Well, that escalated quickly.

When Coronacast left you last year, there were nearly 4000 national daily cases. Yesterday, there were more than 72,000 and there's no sign it's slowing down.

Health systems in most states and territories are beginning to groan under significant pressure.

Add to it probably more than one or two hundred thousand cases a day going unreported, it's fair to say COVID in Australia is in a bit of a mess.

So on today's Coronacast - which will be coming out weekly for at least the next few weeks - when might the peak be here? And what can we expect in coming days and weeks?
