Located just 11 kilometres from the busy centre of Brisbane, Mansfield is a suburb that is very rich in environmental assets. Originally used for dairy cattle and sheep grazing, the district underwent a population boom in the 1960s when government-housing estates were established in the area. Thankfully, someone at the time had the foresight to keep the banks of Bulimba Creek free from development, helping to establish an excellent wildlife corridor through the suburb that has persisted to the present day.
