Petrie Airfield (A1)

The closure was a direct result of urban development. The airfield was located on land owned by the adjacent Petrie Paper Mill (owned by Amcor), which had ceased operations. The entire site was sold to the Moreton Bay Regional Council and designated a 'Priority Development Area' (PDA) by the Queensland Government for a large-scale urban renewal project. The land's value for development far exceeded its value as a private airfield.

The site of the former airfield has been completely transformed and is unrecognizable. It is now the location of 'The Mill at Moreton Bay,' a major strategic development. The most prominent feature is the University of the Sunshine Coast (UniSC) Moreton Bay campus, which opened in 2020. The area also includes new roads, public green spaces, sports facilities, and ongoing construction for future residential, retail, and commercial precincts. There are no physical remnants of the runway or aviation infrastructure.

Established circa 1958, Petrie Airfield (often referred to as Lawnton Airfield) was a significant private general aviation facility for over 50 years. It was located on the floodplains of the North Pine River. The airfield primarily served recreational pilots, local businesses, and employees of the adjacent paper mill. It was home to the Caboolture Gliding Club for a period before their move to Caboolture Airport and was also used for flight training by the Redcliffe Aero Club. The airfield consisted of a single grass/dirt runway (approximately 900-1000 meters long, orientation 11/29) and basic facilities, representing a classic era of local, informal aviation in Australia.

There are zero prospects for the airfield to reopen. The land has been permanently and irreversibly redeveloped into a high-density educational and urban hub. The region's general aviation community is now served by other established airports, primarily Redcliffe Airport (YRED) to the east and Caboolture Airport (YCAB) to the north.
