The definition of a CT case vs a border case makes a huge difference.
I think you're being extremely picky about how/what something is called when it really doesn't matter.
MoH know the details / what each case is, they make decisions based on those facts, if there's CT by the new definition then it probably ties in better with decisions made by cabinet under advice from experts as to whether to lock down or not and to what level.
If your argument is that we're downplaying potential risk because of either the high numbers coming through MIQ (ie more than double on a population basis compared to Aus) or how we've had too many glitches, then sure that's a valid argument - but what we call those particular cases makes no difference, so long as we can still see what's going on.
