Sydney Airport air traffic controller shortages and near-miss incidents cause delays

Consensus Summary

Sydney Airport has been plagued by severe air traffic controller shortages, leading to widespread flight delays and two near-miss incidents in recent weeks. On Sunday, more than 150 flights were delayed as a Jetstar plane narrowly avoided colliding with a Qatar Airways plane on the tarmac, prompting the temporary stand-down of two workers for drug and alcohol testing. The Guardian and ABC both report that the incident occurred early on Sunday, with the airport already grappling with rostering issues that had caused disruptions for days. Airservices Australia implemented Air Traffic Flow Management measures, including spacing out departures, to mitigate the chaos, though the delays affected thousands of passengers and disrupted airline schedules nationwide.

The current crisis stems from a combination of factors, including a mass retirement of 140 experienced air traffic controllers in 2021 during the pandemic, when many chose early redundancy due to grounded flights. While Airservices Australia has since endorsed 245 new controllers—most qualifying in 2025-2026—86 others left the organization over the same period, leaving the workforce stretched thin. Training a new controller takes 18 months, and only about 15 out of 2,000 applicants are hired annually, creating a bottleneck that has persisted for years. The Guardian notes that the organization’s recruitment struggles are compounded by workplace culture issues, with 27% of staff reporting bullying in 2023, up from 23% in 2020, further discouraging retention.

Key figures in the crisis include Federal Transport Minister Catherine King, who condemned the delays as 'unacceptable' and met with Airservices Australia CEO Rob Sharp to demand improved rostering practices starting early September. The Australian Transport Safety Bureau (ATSB) is investigating both the Sunday near-miss and a previous incident on 27 July, where Qantas flights were given contradictory instructions. The ABC reports that the ATSB will examine whether systemic issues, such as understaffing, contributed to the near-collisions. Meanwhile, Scott Nugent, president of the air traffic controllers’ union Civil Air, told multiple outlets that controllers are exhausted from excessive overtime, with some working 10 days on and 1 day off, or logging more than 20 extra hours a week over the past four or five years.

While the outlets largely agree on the core issues—staffing shortages, near-miss incidents, and the need for rostering reforms—they differ in emphasis and specific details. The Guardian provides deeper context on the training pipeline, noting that newly qualified controllers can only fill niche roles, such as managing taxiways at the domestic airport, not international runways. The ABC focuses more on the human toll, including the injury to a Jetstar cabin crew member and the potential role of a tug driver not following instructions. The Sydney Morning Herald highlights the broader impact on Sydney’s reputation as a global city and the frustration among airlines, which have repeatedly raised concerns about Airservices Australia’s lack of transparency. Despite these differences, all sources agree that the situation remains critical and requires urgent action.

The immediate next steps include the implementation of improved rostering practices in early September, though the Guardian cautions that this may not fully resolve the underlying staffing crisis. Airservices Australia has also committed to enhancing its training pipeline, with 95 new controllers expected to be endorsed by the end of 2026, though the ABC suggests the backlog of delays and near-misses indicates more needs to be done. The ATSB’s investigation will determine whether individual errors or systemic failures contributed to the incidents, potentially leading to further reforms. Until then, passengers and airlines continue to face significant disruptions, with the Guardian and SMH both warning that the situation could persist for weeks.
