Why isn't far southern Western Australia more populated?
I was looking at a map of Australia and noticed that the far southern coastal part of Western Australia from Bunbury to Esperance seems surprisingly empty compared to how much coastline it has. Places around Perth are populated of course, but once you go farther south and east it seems like there are huge stretches with very few people despite having a much milder climate than the interior.
Is there a specific geographic or economic reason for this? From a distance it looks like some of those coastal areas could support larger cities or at least more regional development. I know Australia overall has a very centralized population pattern, but southern WA still stands out to me because it’s not deep desert like the center of the country.
Is it mainly due to lack of water, poor soil, isolation from other major population centers, limited industry, or something else? Curious what the historical/geographic explanation is.
