Geography and the role and function of place

The Toowoomba SA4 is made up of 15 SA2s, situated 130km west of Brisbane, directly adjacent to Ipswich. The SA4's relatively small surface area is attributed to it's larger population density, characteristic of a regional centre. Boasting an array of economic and social industries, Toowoomba will experience consistent growth throughout the forecast period.

As one of the oldest and second largest inland cities in Australia, Toowoomba's colonial history revolves largely around its agricultural success, temperate climate, and proximity to other early settlements. The region expands radially around Toowoomba Railway Station in Toowoomba Central SA2, as north as the suburb of Geham and as south as Cambooya, then reaching east into Lockyer Valley, a region shared between Toowoomba SA4 and Ipswich SA4. The forecast population growth is dispersed relatively evenly north, south, and west of the town centre, and tends to follow areas with developable land. Toowoomba - West SA2 is expected to experience the largest share of this growth, resultant of its immense supply of such land. Functionally, the region acts as a natural periphery to the rapidly expanding Ipswich population hub, attracting new migrants and young families looking for cheaper, and more accessible housing options in a relatively short distance from Brisbane.

In terms of transport, the region benefits from a two-hour passenger train linking Brisbane and Toowoomba. Around town, the region also benefits from a frequent passenger bus service, interconnecting it's suburbs. The peripheral suburbs of Toowoomba must rely on private transportation to navigate the city.
