148 Kippen Street, SOUTH MACKAY QLD 4740

As its name suggests, the suburb of South Mackay is immediately to the south of the central suburb of Mackay. Adjoining the Coral Sea, South Mackay has flat land just above sea level apart from a small hill (approx 10 metres above sea level) in the south-east of the locality. The flat nature of the land made it suitable for use as an airport. The Mackay Airport occupies the south-eastern half of the suburb with suburban development in the north and west of the suburb. There are a number of sports fields between the airport and the residential areas, including the Souths Rugby League Club, the Souths Hockey Club, the City Brothers Football Club and Harrup Park Country Club (hosting a number of sports include the Mackay Cricket Association and AFL Mackay).

Mackay State High School opened on 5 February 1912 as part of the Mackay Technical College in Alfred Street, Mackay. 76 students presented for entry examinations on the first day. In 1959, the high school was relocated to a new campus in Milton Street, South Mackay. In July 1927, the Mackay Chamber of Commerce became aware that the Australian Government was thinking of establishing airmail services within Australia "wherever they could be justified". In January 1928, the Mackay Chamber of Commerce first considered creating an aerodrome to prepare for the growth in air traffic, suggesting in March 1928 that the Town Common might be a suitable location. In April 1928 the Mackay City Council voted to provide the land if an aerodrome was required. In September 1928, Captain John Henry Arthur Treacy, chief pilot of the Queensland Air Navigation Co. Ltd., flew over Mackay looking for suitable locations and confirmed that the Town Common appeared very suitable and could be converted to an aerodrome at very little cost. In July 1929, Captain Treacy tells Mackay to create an aerodrome as the coastal air service will soon commence at other towns' aerodromes while Mackay will miss out; he again confirmed the suitability of the town commons as a site. In October 1929, the Chamber of Commerce was advised that, if Mackay had an aerodrome, it would be included in the plans for an airmail service to be commenced by the Australian Postmaster General's department that would visit Mackay three or four times a week. In February 1930, the Mackay City Council was advised by the Controller of Civil Aviation that the town commons site would be suitable after the trees and shrubs removed and the surface made firm and even. Based on an estimated cost of these works to be £250, the council voted to proceed with setting aside the land on the town commons for an aerodrome. On Monday 21 April 1930, approximately 2,000 people cheered as the monoplane Star of Townsville under the command of Captain Treacy landed on the new Mackay Aerodrome (the former Town Common). The mayor of Mackay, Alderman Wood, then officially opened the aerodrome. In January 1931, the aerodrome was approved and licensed by the Civil Aviation branch of the Defence Department as being suitable for all types of land aeroplanes, enabling the council to begin charging landing fees.
