Court documents have revealed the Kyle and Jackie O drama may have been going on longer than initially believed
Jackie “O” Henderson raised repeated concerns with senior executives at ARN Media about co‑host Kyle Sandilands’ behaviour as far back as August 2025 – six months before the on‑air confrontation that ended their blockbuster radio partnership – according to newly released Federal Court documents.
Henderson, who is now suing ARN for at least $82 million over what she claims was her wrongful termination, alleges the company failed to provide a safe workplace, ignored her complaints, and then retaliated against her when she formally objected to Sandilands’ conduct.
The Kyle and Jackie O Show, a ratings juggernaut in Sydney breakfast radio for more than two decades, collapsed in February after a fiery clash in which Sandilands accused Henderson of being “almost unworkable”, “off with the fairies” and obsessed with astrology.
Court filings show Henderson first escalated concerns in August 2025, after an on‑air segment in which she says Sandilands made “offensive and degrading” comments about her character and personal life.
During the 20 August broadcast, Sandilands allegedly described some of Henderson’s on‑air remarks as “psycho‑babble” and told her: “you’ll never find anyone because there is, all of these requirements that you have…”. When she protested, saying “don’t attack me”, he replied: “This is talking, this isn’t attacking… you need to drop all the hype words,” according to her statement of claim.
Henderson is said to have walked out of the studio after telling him “you’re pushing me too far”. Sandilands then allegedly referred on air to her “period time”.
She later took her concerns to KIIS FM’s head of network, Derek Bargwanna, and the show’s executive producer, Natalie Penfold, saying she had been subjected to “degrading” comments and pushed beyond what she considered acceptable.
The tensions did not abate. On 11 September 2025, a day after another on‑air dispute, Bargwanna texted Henderson asking if she was okay. Her response, now central to her case, suggests the situation had become a broader reputational issue for the station.
“Yeah it’s fine today,” she wrote. “But let’s make sure Hamish [McLennan] and Ciaran [Davis] start to think about how to address this. We are getting a lot of complaints from listeners, calling it an abusive relationship, women especially. I can send you though some [of] the examples.”
Bargwanna replied that he was “all over that” and had spoken with ARN chairman Hamish McLennan and then‑chief executive Ciaran Davis about the behaviour on at least two occasions, according to the documents.
Henderson’s lawyers say this and other communications show senior ARN executives were fully aware of her concerns from at least September 2025, undermining any suggestion that the explosive on‑air incident in February 2026 was an isolated blow‑up.
The February on‑air implosion
The long‑running partnership finally unravelled on 20 February 2026 during a segment involving an astrology birth chart for Andrew Mountbatten‑Windsor.
Sandilands lashed Henderson’s interest in astrology, telling her: “Your fixation on this has made you almost unworkable,” and accusing her of being “off with the fairies with this s---, it’s mental.” He said her focus on astrology made her sound like a “drug addict” – remarks that cut deeply given Henderson has previously spoken about seeking treatment for addiction in 2022.
Henderson told him the attack was “so unfair” and said: “I would never say things like that about you… to say ‘you don’t know what the F is going on, you’re not doing your job,’ that’s an attack and I wouldn’t do that.” She left the studio mid‑show and did not return.
Her statement of claim alleges that ARN, which owns KIIS FM, failed to intervene during the exchange and “did not otherwise stop Mr Sandilands engaging in the conduct”.
The following day, 21 February, Henderson texted ARN chief executive Michael Stephenson and chief content officer Kerri Elstub, describing Sandilands’ conduct as “unfair, inappropriate and completely unprovoked” and asking whether new “boundaries and expectations” would be put in place.
Within a week she lodged a formal complaint, claiming ARN had not provided a psychologically safe workplace and stating she could not continue to work with Sandilands in the breakfast slot. Her lawyers say she indicated she was prepared to honour her long‑term contract with the company, provided she did not have to return to that show and was offered an alternative program.
Instead, Henderson alleges she received a letter from the company treating her complaint itself as a breach of her contract – what her legal team characterises as a repudiation of the agreement.
On 3 March, ARN announced the Kyle and Jackie O breakfast show would be taken off air immediately, telling the sharemarket and the public that Henderson had said she could no longer work with her long‑time co‑host. Her lawsuit claims that ASX announcement contained “misleading and deceptive statements” about the circumstances of her exit and about whether she had been offered a new show.
Henderson maintains no such offer was made before her contract was terminated on 3 March.
$82 million claim and allegations of retaliation
$82.25 million in damages for lost contract fees, reputational damage and the pain, distress, hurt and humiliation she says she has suffered.
The claim centres on three main planks:
-
That ARN wrongfully terminated her 10‑year deal, which formed part of a record contract worth up to $200 million and scheduled to run until December 2034.
-
That the company breached workplace health and safety obligations by failing to protect her psychosocial health while she was on air with Sandilands.
-
That it unlawfully retaliated against her for exercising her right to complain about alleged bullying and abusive conduct.
In a recent statement to the ASX, ARN acknowledged Henderson had lodged “psychosocial health and safety and bullying complaints” about Sandilands’ conduct both on and before 20 February, and said she had indicated she could not continue working with him. The company has yet to file its defence to her Federal Court claim.
Parallel case from Sandilands
Sandilands has launched his own Federal Court action after ARN also tore up his contract, citing “serious misconduct” in relation to his behaviour during the 20 February broadcast.
His legal team argues he was engaged – and handsomely paid – specifically to play a “robust” on‑air persona.
After Henderson’s departure, Sandilands was allegedly given two weeks to “remedy” the situation but was barred from contacting her and was himself pulled off the air.
He is reportedly seeking more than $80 million from ARN and has publicly framed the fallout in financial terms, saying he has “a mortgage to pay like everyone else” as he pursues his claim.
A shattered powerhouse for ARN
The collapse of the Kyle and Jackie O Show has blown a hole in ARN’s business. The program dominated Sydney FM ratings for more than 20 years with its provocative, often sexually charged content, and underpinned the company’s high‑stakes bet on a 10‑year, $200 million contract signed in late 2023.
Since the pair’s implosion, the broadcaster’s market value has plunged. ARN Media is now worth about $61.1 million, with its shares closing at 20¢ on Wednesday – down 51% since the start of the year.
The twin lawsuits from its former star presenters, each exceeding $80 million, now threaten to further destabilise the embattled company as it grapples with the reputational and financial fallout from the breakdown of one of Australian radio’s longest‑running and most lucrative partnerships.
Henderson’s case is listed for its first court mention later this month. ARN and Commonwealth Broadcasting Corporation, which operates KIIS under the ARN umbrella in the legal claim, are yet to formally respond in court to her detailed allegations.
