1/ Maybe it's time for a 'Flood Disaster Response' 101.
Lots of folk in 'first-responder world' will know much of this, so feel free to switch off or mute.
Firstly, floods are the most widespread weather related hazard in the world. If you live in a flood plain, you really have 2/
to expect floods.
Floods are DANGEROUS. We think of water as something to swim in, or drink or for play. Moving water carries with it a HUGE amount of energy- a cubic meter weighs 1000kg, & as the speed of it doubles, its energy increase by a factor of 4!
The lateral force of

I’ve been thinking about the disparities between ‘what is known’ about #COVID19, and what our response has been in Australia.
A brief flirtation with ‘herd immunity’, make-believe apps, schools, children, and now most recently, masks has many on this platform pondering on whether those responsible for our response are up to speed. What if another approach was in play? What if the appropriate responses have been ‘attenuated’, according to the implications they carry? This is the explanation that dare not speak its name...
Need everyone back to work, and...

I’m on a late, and really should have a nap, but not before addressing this mendacity.
Firstly, it is the role of Public Health to respond in an emergency- no doubt.
But in the Aged Care sector, that emergency has been made orders of magnitude worse by the failures of federal... regulation and oversight. The set up of the AC Sector in Australia, and the preparedness for such an event, is absolutely as bad the RC has been told, only emphasised by the clown-like appearance and performance of public servants in their attempts to defend it. @SquigglyRick has

So NSW Health has ‘released’ their report on school #COVID19 transmission today, although the only place it can be found is in the press.
So let’s look at what we know from the reporting.
Dates of recruitment not provided.
(Before peak? At peak? After peak)
Involves contact... tracing of 9 students, and 9 teachers. These sentinel cases were presumably identified via SYMPTOMS (not specified) in a cohort notorious for not manifesting with ‘symptoms’.
Despite the suggestion by the authors that the ‘transmission’ rate is ‘extraordinarily low’, it’s not...

So for reasons that I can't entirely fathom, 5000 of you have found my witterings tolerable, and for that I am humbled and gratified.
I thought that I would mark the occasion with some numbers that pertain to #COVID19au, given that it's the topic of the season. Numbers are useful things, and allow us to do all sorts of planning.
Sadly, we are seeing the emergence of arithmophobia with regards to #COVID19au- it's becoming painfully clear that the daily briefing for anyone being asked to officially comment on the situation contains the

Thanks to all who've been sending some really interesting ideas and questions about #COVID19au.
I'm off today, and at a loose end, so thought I might summarize some of the themes about the situation that y'all seem to be interested in. Why is #COVID2019AU such a bitch?
1) It's new. Not everything that is new is brilliant. #COVID2019AU is not the latest iPhone. As a species, we've not met her before, and she is definitely making hay while the sun shine. We have no immunological 'memory' of who she is, so instead

So-
let’s work through this statement methodically, and see if we can find any persistent errors of science or interpretation, despite the EXTENSIVE detail available in the Inquiry itself.
[spoiler- we can, and there’s a few, so stay with me...] 1/
We start with ‘The Message’- not so much a scientific fact as such, but an assumption.
Here the assumption is not even stated, but just implied, to suggest that ‘The Message’ that is provided by #pilltesting is presumably ‘a bad thing’.
By keeping it vague, we can avoid the...
