South Australia - Outback SA4 is made up of 15 SA2s which cover approximately 10% of Australia's surface area. Contrasted by rugged outback and bustling sea towns, the region is the perfect representation of Australia's developable land restrictions. From the centre of the SA4, the region expands over 500km in each direction funneling south into the Eyre Peninsula. At the top of the funnel, significant populations begin around Port Augusta and Ceduna, and then towards Whyalla, the most populous centre of the region, then proceeds downwards to the tip of the Peninsula in Port Lincoln, where the majority of the region's future growth is located. 

Concentrated in the Eyre Peninsula, the region's population centres generally revolve around mining towns in the 'Iron Triangle' like Port Augusta and Whyalla, or along historic trading routes like Port Lincoln. These regions generally expand in population once a resource or route is identified, and maintain as such until the resource is exhausted and then decline, or, the town evolves beyond its original purpose and attracts growth through other methods.

In terms of transport, the regions relies heavily on personal transportation given its remoteness and sheer size. The trainlines functional within the region are used only for commercial and tourism purposes.
