Sydney Airport is at the centre of a unique aviation idea: temporarily switching off its air traffic control tower at night to enable its limited air traffic controllers to work at a time when the airport is most crowded. Airlines for Australia & New Zealand, which represents Qantas, Jetstar and Virgin Australia, has lent its backing to the plan since it thinks of ways to alleviate the chronic shortage of air traffic controllers and ensuing delays that make life difficult for the busiest airport in Australia. Stephen Beckett, the group’s CEO, stated that the proposal is an idea that should be pursued.
Closing an airport control tower may seem unusual at first. Nevertheless, Sydney’s current operating regulations make the plan more feasible than one might assume. The airport has a regular curfew of 11 p.m. and 6 a.m., which means there is already a restriction on most scheduled commercial operations throughout the night. Sydney Airport also claims that its passenger terminals operate for a limited amount of time overnight, regardless of the fact that limited aircraft movements could still occur.
Hence, the main purpose is not to save energy or simply shorten operations. It is about finding a solution that will enable transferring people where the necessity is greatest.
According to the plan, closing tower operations at night would provide the opportunity for two air traffic controllers to work during the day in Sydney, where there is significantly higher demand. Airservices Australia, which is in charge of airspace management in Australia and provides air traffic control for the major airports in the country, informed us that it was looking for new ways to improve the efficiency of its workforce. Any changes to the air traffic operation in Sydney will require a thorough safety analysis and approval from CASA. As for September 18, CASA explained it had not yet received the application for that purpose.
The proposal comes amid growing operational troubles. There has been a near-miss incident involving two Qantas planes on July 27, 2026, in Sydney Airport. Further investigations based on the internal documents revealed that the two working at the moment of the incident had considerable chances of fatigue. The incident has become the first of many near-miss situations that occurred during the month and raised new concerns about the quality of staffing, workload distribution, and tiredness reduction.
The strain has also been apparent to customers used to flying. In August, Qantas CEO Vanessa Hudson stated that action was necessary due to the impact on approximately 60,000 passengers in July alone. Then, just one controller’s unexplained absence on September 11 caused serious delays, highlighting how little leeway is sometimes present in current staffing arrangements.
Airservices has insisted that safety is never jeopardised in the presence of its staffing issues, as it can decrease its traffic to ensure safe operations. On 10 August 2026, CEO Rob Sharp stated that the company was increasing its pool of standby controllers, hiring more staff, and expanding its training capabilities, with particular focus on a brand new simulator tower in Sydney.
Although the overnight tower plan brings forth a startling query: Is it possible for an airport to perform its operations safely even as the main tower is rendered inactive during its hours of night? Uncertainty persists regarding the response to this question. This is especially true because there are certain flights that are not affected by the curfew and can therefore still conduct their operations at night, so procedures have to be developed for such flights too. For now, the initiative is still being considered, but it is quite obvious that it has become very urgent for airlines to discover a solution for the current air traffic control personnel crisis.
