A terminal diagnosis wasn't the deciding factor - an overlooked entitlement was
An employer told a terminally ill worker his job had ended by law. The Fair Work Commission found he was dismissed.
An aviation company told a long-serving helicopter pilot that his employment contract had simply ended on its own - so, on the company's case, it had never dismissed him. The Fair Work Commission saw it differently.
In a decision handed down on August 10, 2026, the Commission found the pilot had in fact been dismissed, rejecting the company's argument that his contract had lapsed by law.
The pilot, an aircraft captain of more than 23 years, had been off work since December 2022 after being diagnosed with a serious illness, later found to be terminal. By early 2026 his income protection payments had ended and he had used up his annual and personal leave, and he was drawing on his long service leave to stay paid while absent. An independent medical examination confirmed he was permanently unfit to fly again, and that no treatment would change that.
On April 2, 2026, the company told him his contract had been "frustrated." Frustration is a legal doctrine: when an unforeseen event makes a contract impossible to perform, it can end automatically, without either side terminating it. The stakes were high. No dismissal means no general protections claim - so if the company was right, there was nothing for the pilot to bring.
He argued he had been dismissed and lodged a general protections application. The company objected, saying the Commission had no jurisdiction because there had been no dismissal.
The leave balance decided it. As at April 2, 2026, the pilot still held 119 days of accrued long service leave - just under 24 weeks - and was using it as paid leave. The Commission found the contract was still operating on its terms, because he was on leave he was entitled to take and the time for him to return to work had not yet come. On that footing, the only way the contract could end was for someone to terminate it.
That, the Commission found, is what happened. As the decision put it, "if the Employment Contract was not frustrated on 2 April 2026, it was terminated at the Respondent's initiative, which gave rise to a dismissal." The decision added that those who take "a mistaken view as to frustration must deal with the consequences of that mistake."
The medical evidence was not in dispute - both sides accepted the pilot would never fly again. But frustration is measured against the contract's terms and the surrounding circumstances, not the diagnosis alone. With months of paid leave still available to him, the contract had not become impossible to perform on the day the company said it had.
The Commission also flagged an evidence gap. The company's own witness said nothing about long service leave, and the company produced no document showing how that leave was administered, despite being best placed to do so. The Commission inferred the pilot would have kept drawing his leave until it ran out, but for the company ending the contract.
One thread was left open. The pilot gave evidence suggesting his exit was connected to avoiding a redundancy payment - he had lodged an expression of interest in voluntary redundancy in January 2026 - and argued the frustration point was a "ruse." The company wholly denied that. The Commission was clear that those questions were not part of this ruling and are for a later stage or a court to decide.
For HR, the lesson is direct. Permanent incapacity, even a terminal diagnosis backed by agreed medical evidence, does not automatically end a contract by frustration. If an employee is still drawing on paid entitlements they are allowed to take, the contract may still be alive - and treating it as "frustrated" can turn into an employer-initiated dismissal, with the exposure that follows. Before reaching for the doctrine, check the leave balances, read the contract and any enterprise agreement, and be ready to prove how those entitlements work. The Commission placed the onus squarely on the party claiming frustration.
The company's objection was dismissed. The matter now goes to a conciliation conference before the Commission.
