Definitely true, and that's also one of the reasons Australia has had it so mildly on the global scale. South Australia has had, I think, only four deaths, and this unbelievably low number is, I think, one of the benefits of being on the island of Australia, and not being particularly recognised as a tourist destination in the way Sydney and Melbourne and various part of Queensland are.

ie. South Australia has the ocean borders of Australia and the psychological borders of unpopularity. The combination of which has proven incredibly effective.
