Millions of Queenslanders will be hoping for good news today when announcements are made whether Brisbane's lockdown will end or continue in some way.

Yesterday saw two community cases of transmission in Queensland, and one popping up in northern New South Wales.

While it's hoped that health authorities are getting on top of things, it will still be a few days before we know for sure.

That's on today's Coronacast.

Also on the show:

* Federal-State relations getting a touch tetchy

* More worries about AstraZeneca and reports of blood clots

* The DL on making mRNA vaccines in Australia. Is it really that hard?
