NSW has 3000 in quarantine - the price you pay for being the nations gateway. But the reality is ther is buigger all in the community and less community spread.Two today in a population of 7.5m and one was from Vic.You can probably note the ones taking potshots at each other are on opposite sides of politics. That being said their points are actually probably both right from their own point of view.
From a NSW point of view - They want to get the economy going with the current levels they have as they are extremely low on a world scale They have a higher level of infection than the states they are requesting to open borders with so not much to lose on that front.
From a Qld/WA POV - keep you filthy Rona infested people out of my state.
Will the states that lock down their borders want economic support later on?
