Brisbane, founded in 1824 as one of Australia’s penal colonies and now Australia’s third largest urban center, is seen in the southeast corner of this low-oblique, south-looking photograph. Brisbane, the capital of Queensland, occupies the rolling terrain on either side of the Brisbane River, spreading eastward to Moreton Bay and westward into the foothills of the Great Dividing Range. Brisbane’s major commercial industries include shipyards, oil and sugar refineries, food processing plants, textile mills, automobile plants, agriculture products, machinery manufacturing, and railroad workshops. The large runway of the Brisbane International Airport is west of the Brisbane River near the river’s entrance into Moreton Bay. The bay, which serves as the entrance to the Port of Brisbane, is 65 miles (105 kilometers) long and 20 miles (32 kilometers) wide.
