Overly inflammatory headlines aside (no strong evidence for this age-specific spread I believe) - this is some very bad luck to now have B.1.617.2 (Delta, a VOC) on top of B.1.617.1 (Kappa, a VUI) get out of hotel quarantine & into the community at the same time.
VOC - VIU info: who.int/en/activities/…
Other sites in Australia have hosted Delta variant infected people including NSW, VIC, QLD, WA and the NT
05JUN2021 Prof Sharon Lewin noting that ~20-30% of cases in Quaraneitne can't be sequenced for technical reasons (presumably low viral load at time of sampling, or poor specimen quality). So could have been a case in VIC HQ that just wasn't able to be identified using sequencing
Also, notes no real evidence for better transmission among children (even from best, UK-based data) - just anecdote.
No exact match to any other B.1.617s sequenced in Aus (some submit sequences to GISAID first then to AusTrakka - which has limited access compared to GISAID [all seem to submit to GISAID eventually though])

@4corners notes Australia's strategy to vaccinate has been shrouded in secrecy.
Interesting watching a GP basically tell an elderly person, don't worry about clots, when they asked what to do if that happens
Pfizer contacted Aus for "informal" discussions in a June 2020. No deal until Nov 2020.
AZ was a known platform, simple cold chain.
SciTAG met in mid-Aug to review the landscape.
C'wealth kept vaccine planning to itself, States lacking info

With recent reminders of ever -present epidemic of death & disruption caused by domestic violence, it's a good feeling to be able to help out a little today. Our family is helping furnish a new DV sanctuary house for a mum & her young kids. Somewhere to be safe & call their own. Image
As a kid, I grew up around one scary male parent, had 2 "fathers" & saw the impact of alcohol & toxic male anger time & time again. I especially identify with the kids in these relationships. And I marvel at the strength of the Mums.
Organisations like Friends with Dignity @friendswdignity seek donations of goods & time, cash and corporate sponsorship.

Seattle’s Leaders Let Scientists Take the Lead. New York’s Did Not
-an old read but was still on my phone. This in particular..
"the researchers, in quiet violation of C.D.C. guidance, had jury-rigged a coronavirus test in their lab"
newyorker.com/magazine/2020/… via @NewYorker
As Australia gets closer to setting up its own CDC it should be written into its DNA that it will never, NEVER be able to prevent or overrule or control the abilities of regional expertise to rapid, flexibly & independently develop & use tests.
That agile independence was one of the key first tools that set successful countries like us apart from others. That changed shortly after as other things distinguished us. But one of the first and best successes was our expert lab network's ability

On this "Australia" day I'm extremely grateful for the jurisdictional across which advised State leaders on COVID-19. I'm also grateful that State leaders listened & acted on that advice. I'm grateful for our established health systems that could support that advice.
We never have openly chased down eradication (local elimination) of SARS-CoV-2 transmission, but in saving lives, reducing fear & protecting livelihoods, Australia got to the same point just via a different route.
By aiming to address fear, prevent illness and support jobs, Australia's leaders really couldn't have ended up anywhere but eradicating SARS-CoV-2 from within its borders. That's what was needed to meet those goals. We've seen that "living with the virus" is actually
