Well you seem to be ok with that? You're completely fine with the rich and famous being brought in while tens of thousands of Australians remain stranded.
This is the question, we always see a number (that remains constant) as 30,000 or 40,000 stranded Australians. The government has abrogated responsibility (other than the arguably token, inefficient "rescue flights") as there is very little political imperative to do so. And the media just craft stories around individuals without delving into any research - 95% of Australians just don't care.
There are likely to be different types of "stranded" Australians. I'm sure half a dozen of AFF'ers with links to overseas could meet and come up with a number of categories in a few hours, so why can't the government? This would be based on the overseas Australians financial ability to support themselves and visa status in the foreign country, to sort out the truly vulnerable and stranded from those, for example, who want to come home because they are not happy with the life they are living (despite having, for example ongoing employment, financial security and valid visas or passports that allow them to remain in the country where they are). Then they may be a category around terminal illnesses and vulnerable relatives etc.
Also, it has been 12 months. I am sure, by now the government could come up with a scheme working with the inbound carriers to provide additional capacity for them to carry those in the truly vulnerable group, but of course this sort of thing isn't as worthy of media soundbites as QF flights.
Then the quarantine itself, they need to eliminate staff. In Singapore, we had someone clad in full protective gear in the lift getting us to the right floor and we lugged our luggage to the room. The same person did this for each arrival. In Sydney, ADF personnel escorted everyone and carried their luggage to their rooms, was that really necessary? Looking at the other pax on our bus, I estimate that may be 2 out of the 20 really needed help with luggage, certainly not everyone. I walked past a HQ venue last night in SIN, checking in arrivals, and there would have been about 4-5 staff total. In Australia, there was probably 10-15 at least. Just use cameras (make them visible not hidden), and perimeter fencing if you're worried about people escaping. The logic of having hundreds of security personnel stationed on each and every floor (who can't do anything if people are escaping, other than alert the police) just confounds me, just use technology, and let people know you're using it.
And don't get me started on reducing the resource burden by treating people coming from countries within the realm of <0.1 case/hundred thousand/week differently to those with 1000's cases/hundred thousand, let them quarantine at home with monitoring bracelets (thinking China, Taiwan, Singapore, Vietnam here), but that would not be acceptable politically either, such is the fear that's been built up.
