To be honest, I’d disagree with almost all of that and I think you’re contradicting yourself. The cases we got in Australia are overwhelmingly related to international travel, that is by far our riskiest activity. So when reopening the economy, which I agree we have to look to do as soon as possible, the last thing that starts is the international travel, instead we should be looking at getting all the restaurants, services etc up and running with the sorts of restrictions you mentioned (slowly rolling them back) and then move on to the international arrivals.

On quarantine I think we need to continue enforcing it, too many of the cases we have now are related to people who didn’t self quarantine so when we do start up inbound international arrivals again then we’re going to also need enforced quarantine, at the travellers expense, until that traveller can show they’re not a risk (which as you say may not be the current 14 days). Though I wouldn’t expect many high net worth travellers arriving, given the quarantine restrictions I suspect it will more likely be family related travel, parents coming to stay with kids for 3 months kind of thing. Basically the opposite really.

International arrivals are what caused the economy in Australia to be shut down, therefore if we don’t want to do it again then it will be the thing that needs the most restrictions especially since coronavirus is a much smaller issue in Aus than most of the countries those international arrivals will be coming from.
