Likely due to an underlying lack of resources within Airservices Australia, there was an over‑reliance on tactical changes to manage the roster. As a result, cumulative fatigue was not being effectively managed strategically and an over‑reliance on tactical principles did not identify or manage fatigue risks arising from the work schedule.
The ATSB will continue to monitor this safety issue until the anticipated increase in staffing numbers is confirmed by Airservices.
On 16 June 2024, Airservices Australia advised the ASTB:
Airservices is focussed on increasing air traffic control staffing through national and international recruitment campaigns. We are also enhancing internal operational processes to maximise resource availability. This includes an emphasis on training, rostering and accreditation enhancements. We have introduced 38 new controllers into operational positions since June 2023 and expect a further 56 by the end of the 2024 calendar year. Additionally, we have launched an international recruitment campaign for experienced controllers to supplement our traditional recruitment program. A number of candidates have proceeded to letters of offer.
Additionally, Airservices advised on 29 July 2024:
Nine inflows have been added to the North Queensland ATC group since January 2023. Three are currently endorsed and six are in training. These inflows increase our available staff against the staffing requirement for the group. Based on the current data, we expect the master roster to be filled with minimal gaps by October 2024, when available staff meets the requirement.
The ATSB will continue to monitor this safety issue until the anticipated increase in staffing numbers is confirmed by Airservices.
