Radio host Jackie O has filed legal proceedings against radio network ARN, claiming compensation of at least $82.25 million and alleging that her termination was against the Fair Work Act.

This morning, ARN informed its shareholders of its intention to contest Jackie “O” Henderson’s allegations, preparing to challenge the lawsuit in court.

“It’s a complete assault, absolutely. To hear, ‘Kyle, you’re clueless about what’s happening, you’re failing at your role,’ is an outright attack, something I would never do,” remarked Sandilands.

Sandilands and Henderson boast a remarkable 27-year on-air collaboration.

The duo transitioned to the breakfast slot in 2005 and later joined KIIS in 2014.

They are currently engaged in a substantial $200 million contract spanning a decade, which is scheduled to conclude in December 2034.

Full statement from ARN Media regarding Jackie O’s lawsuit

ARN Media Limited [ASX: A1N] has disclosed that Ms. Jacqueline Henderson and her associated company have initiated legal action against ARN.

The proceedings have been filed in the Federal Court against Commonwealth Broadcasting Corporation Pty Ltd (CBC), a subsidiary of ARN which is the licence holder for KIIS 1065 Sydney and contracted with Ms Henderson and her services company. Unsealed copies of Court documents in respect of the proceedings were served on CBC on 30 March 2026 after market close.

In summary, the applicants claim that the termination of Ms Henderson’s contract constituted adverse action. Ms Henderson sent a ‘Complaint Letter’ to CBC which noted that Ms Henderson “cannot continue to work with Mr Kyle Sandilands” and made psychosocial health and safety and bullying complaints in relation to the conduct of Mr Kyle Sandilands on and prior to 20 February 2026. It is alleged that the Complaint Letter involved the exercise or proposal to exercise workplace rights, and that the contract was terminated because of that exercise or proposed exercise, in alleged contravention of section 340 of the Fair Work Act 2009 (Cth). It is also alleged the termination of her contract amounted to a repudiation of that agreement.

The applicants also claim that ARN’s ASX Market announcement of 3 March 2026 included misleading and deceptive statements under the Australian Consumer Law. The applicants claim compensation of ‘at least $82,250,000’, and payment of a pecuniary penalty, plus interest and costs.

ARN disputes the claims. It intends to defend the proceedings. Given the early stage of the matter, ARN is unable to reliably estimate the outcome or any potential financial impact.
