Very few people live in the interior of Australia because the dangers posed by volcanic eruptions make it unsuitable for settlement.

The continent of Australia hosts around nineteen volcanoes throughout its geographic span. Most of these volcanoes are currently inactive but still pose certain dangers to human life.
The activity of these volcanoes cannot be ascertained correctly. Thus, it is because of these volcanoes that the population in Australia prefers to live along the coasts.
