Cooranbong Airport

Economic reasons and land redevelopment. The airport was situated on valuable land owned by the Seventh-day Adventist Church. A decision was made to sell the land for a large-scale residential housing project, as the economic return from the real estate development far exceeded the value of maintaining the private aerodrome.

The airport is permanently closed and no longer exists in an operational capacity. The site has been extensively redeveloped into a large residential housing estate known as 'Watagan Park'. A new road, University Drive, now cuts directly across the former runway. While remnants of the southern portion of the runway's pavement are still visible on satellite imagery, they are overgrown and integrated into the new development. The majority of the airport land is now occupied by houses, streets, and suburban infrastructure. Some of the original hangars may still be standing on the edge of the development, repurposed for other uses.

Cooranbong Airport, also known widely as Avondale Aerodrome, was a private airport established to support the activities of the adjacent Avondale University and the Seventh-day Adventist Church. For decades, it served as a crucial facility for:
- **Flight Training:** It was a base for the university's aviation program, training pilots for both commercial and missionary work.
- **Missionary Aviation:** The airport was a hub for church-related aviation activities, including preparing aircraft and personnel for missions abroad.
- **General Aviation:** It catered to private pilots and aircraft associated with the church and the local community, providing a convenient access point to the region.
- **Transport:** It was used for the transport of church and university officials.
The airport featured a single sealed runway (approximately 960 meters / 3,150 feet) and several hangars.

Zero. There are no plans or prospects for reopening Cooranbong Airport. The land has been permanently and irreversibly converted to residential use. The construction of a housing estate directly on the former runway and airfield makes any future aviation operations at this location impossible due to physical obstruction and safety regulations.
