But time and time again, we have seen contact tracing fail badly.
Do you really think the Vic govt has 100 people sitting in a room just waiting for another outbreak so the contact tracing could be done quickly and efficiently?
I guess the debate for your second point is: what is essential travel? To my mind, there's very little that qualifies. I've watched my husband who used to fly weekly for work manage to do his job effectively from within the house for a year now. He had his first work trip a couple of weeks ago and currently sees nothing in his future that would require another. And I just do not believe that those people that fly overseas for work cannot be replaced by locals, once suitably trained, or that their job cannot be done remotely. What I think is that the will to recruit and train locals isn't there for those companies that import labour. There are a few exceptions, but not that many.
And as for weddings funerals and the like: attend virtually, like we did last year. This is the definition of non-essential travel IMO. You won't stop the person from dying by getting on a plane. And before people start howling me down, yes, this happened to me (with a dying relative) during the Melb lockdown last year. If you choose to live away from loved ones you accept the risk that they may die without you there. Even in pre-covid times, this happened to people all the time. And before the jet age, you'd get a 6 week old letter informing you that Nonna had passed away. Why do we think we are so special now?
