I'd think Starlink will help change this. Not for living in the actual dusty Outback (which has its own risks/dangers/inconveniences), but for living in many other places in Australia that are lovely and not too far from desirable areas.
Most people want to live where other people live, for reasons ranging from social connections to access to services and infrastructure. I doubt broadband access access plays even a small role.
Yeah, like I said, not talking about the boonies. There are plenty of lovely places that are >10km from those two cities, but which are still close enough to services and infrastructure.
