Why is the western region of Australia called outback?

The term "outback" is not exclusively used to refer to the western region of Australia. It is a broad term used to describe the remote, sparsely populated interior regions of Australia, which encompass large areas in the central and western parts of the country. The term "outback" is often used to evoke a sense of the vast, arid, and rugged landscapes that characterize these regions. It implies a sense of being remote and far from major population centers and services.
