Kyle Sandilands and Jackie 'O' Henderson brace for shock face-off in court over axed radio stars' $200million deal

Radio giant ARN plans to confront former co-hosts Kyle Sandilands and Jackie 'O' Henderson in a courtroom showdown to justify terminating their respective $100million contracts.

The company plans to call Henderson as its key witness, alleging Sandilands subjected her to prolonged bullying and harassment on their KIIS FM breakfast show – accusations that emerged after he launched a multimillion-dollar lawsuit over the termination of his contract.

According to The Australian, Henderson has provided ARN with a list of occasions when Sandilands allegedly 'bullied, berated, and belittled her on and off air', including the February 20 incident in which his harsh on-air comments left Henderson in tears.

'Kyle's in for a great deal of pain if he pushes ahead … Jackie has already tipped a real bucket on him behind the scenes to management,' an ARN insider told the publication.

'Jackie's letter outlined numerous instances of unconscionable behaviour towards her (by Sandilands) besides what happened on that fateful day. Her complaints go well beyond those final on-air comments.'

Despite ARN also terminating Henderson's $100million, 10-year contract after she expressed her unwillingness to continue on the Kyle & Jackie O show, the network is now reportedly offering her a return to KIIS FM with a solo program.

'It's also worth noting that Jackie is not taking any legal action (against ARN) – and that's because she is being looked after,' the source added.

Sandilands appeared at the Federal Court on Friday for a directions hearing. He alleges that the termination of his contract with the company was invalid because there was no act of serious misconduct and the termination breached Australian Consumer Law.

According to damning legal letters released by the Federal Court, Henderson refused to present alongside her former radio co-star Sandilands 'ever' again after their relationship broke down in the middle of their February 20 live show.

ARN axed the pair's $200million contract deal after a segment in which Sandilands slammed Henderson for her 'fixation' on astrology.

Henderson said 'that's not fair' and left the studio in tears, before her own $100million contract was terminated.

Less than two weeks later, on March 3, Sandilands received a letter from ARN accusing him of making 'abusive, humiliating, and belittling comments' to Henderson, which included attacks on her character, work ethic, and job performance.

'You stated that everybody at the radio station was talking about these failings, thereby impressing on her the idea that her conduct and performance was so bad, that they were generally the talk of the station,' the letter read.

ARN claimed Sandilands' comments were not made in jest, and demonstrated a 'manifested hostility' towards Henderson that was 'calculated to offend and distress her'.

The broadcaster claimed Sandilands had damaged the business because Henderson refused to 'ever present with you again'.

Days after the blow-up, Henderson released a statement saying she 'did not quit or resign'.

Sandilands was given 14 days to remedy the situation or his contract would be terminated, but ARN did not propose any solutions in either its initial or subsequent correspondence.

He was ordered not to comment on the situation, disparage anyone at ARN, or victimise staff who had complained about his conduct – or risk termination. 

A response from Sandilands' lawyer Kevin Lynch on March 10 claimed the broadcaster was aware of his client's 'tone, style, voice and robust character', to the point where it was willing to pay him $100million.

Mr Lynch also noted that the broadcaster had a 30‑second delay to censor or remove any disparaging comments but chose not to do so.

He said ARN created a 'Catch-22' when Sandilands was not given a way of resolving the situation.

The court also released an affidavit sworn by Mr Lynch, who detailed the pair's respective on‑air roles and their long working relationship.

Mr Lynch said Sandilands was the 'dominant and abrasive personality who is deliberately outrageous and often offensive', while Henderson was a 'warmer and more emotionally attuned character.'

'Mr Kyle Sandilands is one of Australia's most prominent and recognisable radio broadcasters,' Mr Lynch wrote.

'He has been a continuous presence on Australian commercial radio for more than 25 years since his commencement on the commercial radio station known as '2Day FM' in 1999.'

Sandilands has co-hosted The Kyle and Jackie O Show – originally on 2Day FM – since January 2004, before moving to KIIS FM a decade later.

'The program is consistently the highest-rated FM breakfast show in the Sydney metropolitan market,' Mr Lynch wrote.

'The program is high-energy and controversial involving the broadcast of (amongst other things) material that is irreverent and naturally provocative, including using crude humour, ribald comedy and sexual innuendo.'

Mr Lynch said The Kyle and Jackie O Show was 'occasionally controversial'.

'Banter and tension between Mr Sandilands and Ms Henderson is a central dynamic to the program,' he wrote.

'Mr Sandilands generally performs the role of the dominant and abrasive personality who is deliberately outrageous and often offensive, whilst Ms Henderson plays a moderating role as a warmer and more emotionally attuned character.

'The characters which Mr Sandilands and Ms Henderson play are designed to be an exaggeration of their respective personalities.'

Mr Lynch set out the alleged harm done to Sandilands by the termination of his contract.

Sandilands's career and livelihood were 'uniquely dependent upon the maintenance of a continuous, daily relationship with this radio audience,' he wrote.

'Every day that Mr Sandilands is absent from air, the audience relationship that Mr Sandilands has cultivated is subject to erosion as listeners migrate to competitor programmes and form new habits,' he wrote.

Mr Lynch said Sandilands' 'commercial identity', including the value of his 'personal brand', was inextricably linked to his on-air presence, ratings and audience engagement.

'The harm flowing from Mr Sandilands' continued absence from the program is compounding in character: the longer the absence, the more difficult and uncertain the task of audience recovery becomes,' he wrote.

'Radio audience behaviour is such that listeners who are lost during a period of absence may not return, or may not return in the same numbers, once a broadcaster resumes.'

Mr Lynch said the loss of listeners was, to a significant degree, 'irreversible', and the damage arising from that loss 'perhaps impossible' to quantify.

Among the orders Sandilands seeks is his reinstatement.

'Mr Sandilands is willing to work with a co-presenter or, if Ms Henderson is willing, with Ms Henderson,' Mr Lynch wrote.

'He presented the program without Ms Henderson and without issue on previous occasions, including in the days immediately following 20 February 2026.

'ARN has not considered or attempted to allow either such course.'

The matter will return to court on April 24.
