Here at least, all recreation, cinemas, clothing stores, churches, schools, etc. were all closed anyway, so it was irrelevant (although we certainly have at least 3 cinemas and 3 shopping malls - 1 of a very decent size, the others a bit smaller, several churches, etc. - within our 5km). Funnily enough, Costco is one of the few things that is not within my bubble!
It is a very tricky situation. There are a few reasons for the ban.
The first is similar to why there are bans on travel to places like North Korea: it is considered high-risk, you can’t get
travel insurance and the government doesn’t want to face pressure to bail people out if they get sick. Also, as we’ve seen in Victoria, even travellers in hotel quarantine can pose a risk.
The second is that there are so few flights and spots available in hotel quarantine that they don’t want people getting stuck overseas (and again face pressure to arrange repatriation flights, etc.) and to add more names to the backlog of people trying to get back. They are adding more spots at an old miner’s camp in the middle of nowhere in the Northern Territory (it’s apparently actually lovely!) but it is still a lot to work through, especially with airlines having so few seats available.
Finally, even with people having to pay an amount for hotel quarantine, it is still costing a lot of money; the NSW premier this week was complaining about the Queensland and WA governments not paying their fair share of the bill for hotel quarantine while keeping state borders closed.
So, I do agree that it is necessary to prevent Australians from leaving the country for frivolous reasons; there definitely would be people wanting to just vacation and I think it is good to be preventing that at the moment. You can get exemptions including on humanitarian and compassionate grounds, essential business travel, leaving for more than 3 months. The problem is, of course, that there are some people (like those in the article) who get caught up in it unfairly and with the delays that inevitably come with bureaucracy. The same has also happened with people needing exemptions for state border closures. It is undoubtedly really tough for those individuals who it affects but I suppose if we didn’t have these restrictions then there would be even more people unable to say a proper goodbye to loved ones. It is definitely far from ideal (even in my family, my aunt doesn’t know when she’ll be able to see her son and grandkids, including a new one in December, again as they are in Uganda and we don’t know when we’ll be able to see our relatives in London either). But nothing in this pandemic is ideal at all, is it?
