That's one way of putting it.
It's possible that what we might be witnessing here is some last minute power grabbing. The State funding such sites which were rejected by the Commonwealth does create the basis for an ongoing story about protecting Queenslanders for example. The problem is that if the Queensland government is signalling to the business community that long term managed quarantine is the answer, then it creates a pretty big conundrum for tourism.
If NSW has open borders for international travel (from certain countries, fully vaccinated, etc) and QLD doesn't, then all people will do is go to NSW for 2 weeks then go to QLD, or forget about the latter entirely. Similarly, who in NSW would go to QLD for a holiday if they demand quarantine on arrival, when you could just go to a travel bubble nation and come and go freely from overseas?
