Australia's electricity system is facing concerns over operational risks after specialist workers at the Australian Energy Market Operator (AEMO) increased industrial action during a prolonged pay dispute with management.

AEMO is responsible for coordinating Australia's major electricity markets and managing the balance between electricity supply and demand. Its work is critical to maintaining reliable power supplies for millions of households and businesses across the country.

The dispute centres on negotiations for a new enterprise bargaining agreement. Engineers, scientists and other specialist employees represented by Professionals Australia are seeking wage increases linked to inflation, arguing that their salaries should keep pace with the rising cost of living.

The union is seeking pay rises of 4.2 per cent for the current financial year and the following year, with a minimum increase linked to inflation if prices rise more quickly. AEMO has offered annual increases of 4.2 per cent but has not agreed to the additional inflation-linked protection.

Workers have rejected the organisation's offer in three separate votes, increasing pressure on management to reach an agreement.

As negotiations stalled, employees began taking industrial action. Staff working in sensitive control-room operations have introduced indefinite bans on assessing and approving non-critical planned electricity outages.

Workers have also refused to attend certain daily meetings and temporarily paused non-urgent responses to questions from electricity generators and operators of high-voltage transmission infrastructure.

These activities normally help coordinate maintenance, manage network operations and ensure electricity infrastructure can operate safely.

AEMO has warned that the combined effect of the industrial action could create serious operational difficulties. The organisation sought intervention from the Fair Work Commission, arguing that the work restrictions could create catastrophic risks, potentially leading to blackouts and putting lives at risk.

The Fair Work Commission agreed to a limited suspension of some industrial actions while the matter was considered.

However, the union has rejected suggestions that its members would deliberately compromise electricity security. Professionals Australia representative Thomas Whibley said workers were committed to public safety and criticised management's approach to the negotiations.

The disagreement has also extended beyond wages. Some employees have questioned the difference between executive remuneration and ordinary staff pay. More than 100 workers reportedly supported a suggestion that AEMO chief executive Daniel Westerman consider resigning.

Financial statements show that senior executives received approximately $7.2 million in salaries and short-term benefits during the financial year ending June 2026, compared with $6.9 million in the previous year.

AEMO has defended its employment offer, saying it provides competitive wage increases and additional benefits. It has also explained that its operating costs ultimately affect consumers, meaning pay decisions must be balanced against electricity affordability.

Professionals Australia has referred a bargaining application to the Fair Work Commission, which is expected to assist in resolving the dispute.

The situation remains unresolved. Although no nationwide blackout has been announced as a result of the industrial action, the dispute highlights how essential specialist workers are to Australia's electricity network.

A negotiated settlement will be important to restoring workplace relations and ensuring that the country's power system continues operating reliably.
