In Australia, the constitutional amendment from 1967 that specifically allowed the Federal government to intervene to protect indigenous people is considered one of the most important positive steps in addressing historical racism and helping these people - by both indigenous and non-indigenous Australians.
So interventions like this are more often than not seen as a good thing - provided they are done properly. It's not considered equivalent to internment (which Australia also did during the wars) - it's in a separate category of health intervention.
It allows indigenous people to continue to live on their ancestral lands even when it wouldn't normally be viable to do so, because when it's necessary for health reasons, they can be taken somewhere temporarily to receive the care they need. People choose to live in these communities with that understanding.
Thanks for the clarification. That targeted intervention certainly does beat doing things like locking down all of Melbourne or my old state of Maryland (I now live in Florida).
