Radio queen Jackie “O” Henderson has been a no-show at a Sydney court, letting her lawyers do the talking, in her ongoing legal battle with KIIS FM owner ARN.

Henderson’s claim against her former employer was scheduled for a case management hearing at the Federal Court on Thursday morning.

There was no requirement for her to attend.

Her agent, Gemma O’Neill, was in court as the matter was set down to continue towards a trial due to begin on October 12.

The 51-year-old is suing ARN for wrongful termination and a contract payout of at least $82 million, after she and former co-host Kyle Sandilands were sacked by the network in March.

The pair launched separate legal actions against ARN over the termination of their contracts, which were worth $100 million over 10 years.

ARN later filed a cross-claim, but has since abandoned that action following Sandilands’ settlement.

Both were seeking the full payout of the remainder of their 10-year, $100 million contracts signed at the end of 2023.

But ARN claimed the controversial duo cost the company key advertising revenue through their sacking.

ARN previously told the court Henderson sent the station a letter in February claiming her co-host had engaged in “persistent and relentless bullying” against her over about six months.

The radio hosts’ highly public bust-up moved into the legal arena after an exchange between the star pair in February, when Sandilands accused his co-host of being “off with the fairies”.

The on-air comments prompted Henderson to say she could no longer work with her contentious colleague.

The central issue in the legal dispute is determining who at ARN was responsible for making the decision to sack Henderson after she said she could no longer work with her controversial co-star, Henderson’s barrister said.

“We do not know who (ARN) say the decision makers were,” Vanja Bulut said.

ARN on Wednesday confirmed it had settled a similar claim from Sandilands, agreeing to pay him $12 million, including $3 million due as early as July.

Sandilands said he was relieved to put the ordeal behind him when approached by reporters outside his home.

“It’s quite daunting to have that hanging over your head,” he said.

“I could have dragged it on for like a year and a half.”

Sandilands said his team was confident of a legal victory had he pressed on, but he now hopes to use his free time investing in his next project.

“It means I can get back to work rather than annoying my wife. I’m just happy to get out of here in the morning and back to work,” he said.

“I’m just building my own platform … I don’t care if it’s hugely successful or it just keeps the people that were retrenched employed.”

That project may be buoyed by the $1.5 million in advertising services on ARN’s partner platforms that he is owed under the settlement.

In exchange, however, the radio network will be entitled to a 19.9 per cent share of any new venture for three years.

Sandilands will also be prohibited from engaging with any of ARN’s direct competitors for up to nine months from the settlement date.

“This agreement brings certainty for ARN and resolves the legal dispute,” ARN chief executive officer Michael Stephenson said.
