Watching sky news over the past few days their argument was for opening state borders to help with tourism, but if you listen to any people with a medical bias then they say the borders should remained closed.
Medical advice seems to vary on this. Some clearly state it is now unnecessary.
Given the likely number of infected people still in Australia the border restrictions that are in place it would seem to be unlikely to actually prevent any significant number of new cases in the future.
There are quite a number of "essential workers" and other still moving between states and infections from them do not seem to be a significant issue any more.
Early on infections from returning international travellers and from cruise ships (who in turn were infected by internationals) were causing transmission across borders transmissions, but these sources have now been cut off by quarantine.
On the con size is that the economic damage extends many businesses well beyond the tourist market and the mental health damage to many as well who cannot travel but who want to.
So the question to me is are we going to go forward with the control measures in place, including Covid Safe, ramped up contact tracing etc, or are we going to remain in my mind unnecessarily frozen.
Remember to that deaths and severe health problems are a small % of those that actually get infected. So if we say have say 1000 new infections (ignoring the international quarantines that are still occurring, and will continue) that there will only be now a small number of people from that 1000 that we are preventing harm to with these very strict measures. Is preventing harm to that small group, enough to offset the health harm (including mortality) and economic harm (which in turn causes other health harm) to others? To my mind it no longer is.
