As a multicultural immigrant country, why is the population in central and western Australia so small?

The geographical environment in central and western Australia is extremely harsh, mostly desert, and the climate is also very harsh. You can refer to the Sahara desert. This is why many countries have a large land area, but the population is not proportional to the land area. It can be compared with Canada, which has the second largest population in the world but only over 36 million people.

Most of the midwest of Australia is desert. It's too dry. There is no water. No matter how warm the climate is, human beings can't survive. It is better to live in ice and snow than in arid areas, at least you can survive. If survival is unsustainable, let alone life. Most of them are red clay deserts, and the remaining few lands are wasteland sand forests, barren hillsides, or salt lakes in the south, or bare loess only suitable for weed growth, and water resources are extremely scarce.

Most areas suitable for human habitation are plains and hillsides rich in water resources. Australia ranks sixth in the world, with a total area of 7.74 million square kilometers, but the land inhabited by human beings is only over 2 million square kilometers, which is pitiful. The total area of Western Australia is about 2.52 million square kilometers, including Gibson Desert with an area of about10.6 million square kilometers.

Further south, it is almost 300,000 square kilometers of Victoria Desert, and there are other big deserts, such as 4 10000 square kilometers of Dasha Desert. Several deserts add up to about 900,000, leaving about 654,380,600 square kilometers of land, most of which are plains. The arid or semi-arid climate in Western Australia determines the lack of water resources, so the population in Western Australia is very small.
