The Australian state of Western Australia has a population of 2.2 million people, and occupies an area of just over 2.6 million square kilometres. Just for reference, that is seven and a half times the size of Germany or alternatively ten times the size of Texas.
However, average house prices are amongst the highest in the world, as there is a shortage of land.
It rather boggles the mind.
Correction: Texas is actually slightly more than a quarter of the size of Western Australia. My apologies to Texans.
