Facebook, press conferences, closed door meetings between corporate and government... I mean - a COO whining at a press conference that the whole thing 'is bullshit' is a tantrum. That's not the sort of outburst one expects from an executive of a large public corporation
Its very difficult to separate suburbs from each other in the same state. Victoria's 'ring of steel' has been breached numerous times, and has involved an enormous amount of equipment, manpower and logistics. When the 'Logan Liars' breached the border and made false declarations (the source of most cases in recent SEQ times), they had exposures from Ipswich to the Redlands, BCC and Logan council areas. Its impossible to 'separate' that. But you deal with cases in your own backyard. You don't import new ones - you manage the risk with the existing population.
Sydney isn't allowed in even though the rest of NSW is because 'greater sydney' has a lot of crossover. 4 unexplained cases in 3 different localities means the spread could be far larger. Sydney siders work all over. When I lived in Sydney, I lived around the Penrith area, and within a few years (without moving house) I worked from Hornsby, Castle Hill, Parramatta, Cronulla, Eastgardens, Sydney City and everything in between.
The mobility of Sydney means a case in Castle hill can just as easily reach Sutherland as it can Campbelltown. So 'greater sydney' is the hotspot, not 'castle hill'.
It'd be pretty hard to pretend. It hasn't. Anyone who thinks the Premier's position on the Queensland Border has been about politics either needs to stop sucking Murdoch's tit, or declare their LNP membership card at the door.
