Sydney Near-Misses Expose Critical Fatigue Risk

4 September 2026

Executive Summary

A series of near-miss incidents at Sydney Airport has highlighted an often underestimated operational risk for businesses:

fatigue within safety-critical workforces.

Records obtained by Reuters show that during a serious runway incident at Sydney Airport on 27 July, five of the ten air-traffic controllers working at the time had been classified as presenting a high fatigue risk under Airservices Australia’s fatigue-management system.

Two of the three controllers directly involved in the incident were classified as high fatigue risk, while the third was classified as medium risk.

The incident involved a QantasLink turboprop in its landing roll on runway 34L while a Qantas Boeing 737 had been cleared by air traffic control to cross the same runway.

Controllers detected the conflict and warned both crews, with the Boeing 737 stopping after the holding point.

There were no injuries.

The incident subsequently emerged as the first of six near-miss incidents at Sydney Airport within approximately one month, prompting increased scrutiny of staffing, rostering, overtime and fatigue management.

The Australian Transport Safety Bureau is investigating the incidents and has not yet reached final conclusions about their causes.

That distinction is important.

Fatigue has not presently been established by investigators as the cause of the incidents.

A high fatigue-risk classification also does not establish that an individual controller was actually fatigued. The system assesses the risk of fatigue using factors including working hours and scheduling.

Airservices Australia has stressed that safety is not compromised when staffing difficulties arise because traffic levels are reduced where necessary, although this can result in flight delays.

The organisation is also increasing staffing contingencies, reducing overtime and working towards more stable rosters.

The wider risk lesson nevertheless extends far beyond aviation.

A safety system can identify elevated human risk without necessarily eliminating the operational circumstances creating it.

UK Impact

The issue has direct relevance for UK businesses employing people in safety-critical or high-consequence positions.

These include:

• Aviation.
• Rail.
• Road transport.
• Shipping.
• Warehousing.
• Construction.
• Manufacturing.
• Energy.
• Utilities.
• Healthcare.
• Security.
• Critical infrastructure.

Many organisations have formal working-time, shift and fatigue policies.

The more difficult question is whether those policies remain effective during periods of:

• Staff shortages.
• Increased demand.
• Sickness absence.
• Overtime.
• Emergency response.
• Night working.
• Disrupted transport.
• Severe weather.
• Major projects.

A workforce can remain technically within an organisation’s staffing model while individuals become progressively more exposed to fatigue-related error.

For UK businesses, this is particularly important where a single mistake can cause injury, property damage, machinery loss, environmental contamination or prolonged business interruption.

Global Impact

Fatigue is a systemic rather than purely individual risk.

International aviation provides an unusually visible example because safety systems record and investigate near misses extensively.

But similar exposures exist throughout global industry.

A fatigued employee may:

• Misread an instruction.
• Miss an alarm.
• Enter incorrect data.
• Authorise the wrong movement.
• Fail to isolate machinery.
• Misidentify equipment.
• Overlook a maintenance problem.
• Make an incorrect routing decision.
• React too slowly to an emergency.

Automation does not necessarily remove that risk.

In highly automated environments, human intervention can become most important precisely when something unusual occurs.

That means the person required to solve the abnormal situation may have spent hours performing relatively low-stimulation monitoring before suddenly being required to make a high-consequence decision.

The commercial consequences can then extend into:

• Employers’ liability.
• Public liability.
• Property damage.
• Machinery breakdown.
• Marine liability.
• Aviation liability.
• Environmental liability.
• Business interruption.
• Directors’ and officers’ exposure.
• Regulatory investigation.

Our View

Businesses should treat fatigue as a measurable operational risk rather than simply an HR issue.

Boards and risk managers should ask:

• Which roles within our organisation are safety-critical?
• How much overtime are those employees working?
• Are staffing shortages becoming structural?
• How many consecutive shifts are permitted?
• Are night shifts treated differently?
• Is commuting time considered?
• Do employees have sufficient recovery periods?
• Are contractors working additional shifts elsewhere?
• Can supervisors override fatigue warnings?
• What happens when a worker is identified as high risk?
• Is another qualified employee actually available?
• Are production targets encouraging excessive overtime?
• Are near misses recorded?
• Are patterns across near misses analysed?
• Can employees report fatigue without fear of disciplinary consequences?
• Does business-continuity planning assume that key personnel will always be available?
• Could an incident involving fatigue affect insurance or regulatory liability?

The most important distinction is between having a fatigue-management system and acting upon what that system reveals.

A dashboard showing elevated risk does not itself reduce that risk.

The operational question is what happens next.
