Townsville hosts a significant number of governmental, community and major business administrative offices for the northern half of the state. During World War II, the city was host to over 50,000 American and Australian troops and air crew, and it became a major staging point for battles in the South West Pacific.

Townsville is characterised as a tropical savanna climate. Due to a quirk of its geographical location, Townsville's winter rainfall in particular is not as high as elsewhere in the tropics such as Cairns.
