Brisbane Airport will adjust its flight operations to reduce aircraft noise affecting local residents, aiming to limit disruptions in neighbourhoods under current flight paths.
Starting on 28 November, Brisbane Airport will prioritise the use of Simultaneous Opposite Direction Parallel Runway Operations (SODPROPS) during certain times, particularly on weekends and weeknights after 9 p.m., allowing more aircraft to arrive and depart over Moreton Bay rather than residential areas.
This change, directed by Airservices Australia and the federal Transport Minister, is expected to reduce noise disturbances for 300,000 to 500,000 residents affected by previous flight patterns.
Community Concerns and the Push for Quieter Skies
Community groups and local representatives have raised long-standing concerns about Brisbane Airport’s operations’ noise impact, especially since the opening of the second runway in 2020. Residents in affected areas have been vocal about noise levels and are advocating for stronger measures, including a night-time curfew and a cap on the number of flights.
The Brisbane Flight Path Community Alliance also expressed concerns that the proposed increase in SODPROPS usage, from two per cent to five per cent of total flights, may still be insufficient. Representatives from the alliance argue that the SODPROPS mode should be prioritised for more hours each day, not only during limited times when conditions permit.
Airservices Australia and Airport’s Noise Reduction Strategy
Airservices Australia, the authority responsible for air traffic control, stated that increasing SODPROPS usage was a key part of its Noise Action Plan for Brisbane. According to the plan, aircraft using this runway mode will stay over water longer and gain altitude more quickly before crossing into residential airspace, which should reduce the noise impact on the ground.
As part of these measures, aircraft flying over the Redlands area will ascend to 12,000 feet, up from the previous 8,000 feet, to further mitigate noise. Additionally, minor adjustments will be made to arrival flight paths over North Stradbroke Island, including the installation of a noise monitor to ensure transparency and track any impact on local residents.
Brisbane Airport CEO Gert-Jan de Graff has expressed the airport’s commitment to reducing noise, stating that each additional aircraft routed over Moreton Bay lessens the noise impact on neighbouring communities. Brisbane Airport is collaborating with Airservices Australia, airlines, and local stakeholders to balance the airport’s economic role with residents’ quality of life.
Economic and Operational Considerations
While noise concerns continue to drive community advocacy, there are also economic considerations. Brisbane Airport Corporation has indicated that curfews and flight caps could have significant economic repercussions, costing the city around $1 billion annually. Instead, the airport has taken steps to work with international airlines, such as Singapore Airlines, Emirates, and Cathay Pacific, to route more nighttime flights over the bay when winds are favourable, helping limit noise in populated areas.
Airservices Australia has assured the community that further changes to SODPROPS usage are under consideration, with plans to expand the mode’s application in 2025 if traffic conditions and safety standards allow. Community feedback remains central to the ongoing adjustments, as Airservices continues to work closely with Brisbane residents and other stakeholders to address the impact of aircraft noise.
