Former Sydney radio broadcaster Jackie “O” Henderson complained twice about her co-host Kyle Sandilands six months before their public falling-out in February.
Court documents released by the Federal Court on Wednesday state Henderson complained to KIIS FM network’s parent company, ARN Media, about Sandilands’s behaviour in August and September 2025.

The allegations put forward in her statement of claim as part of a wrongful termination claim against Commonwealth Broadcasting Corporation (CBC), a subsidiary of ARN Media, allege she was subject to “offensive and degrading” comments made about her personal and dating life during a broadcast in August 2025.
“I am worried about you on another note, that you’ll never find anyone because there is all of these requirements that you have,” Sandilands said to Henderson during the broadcast.
“… don’t attack me,” Henderson said.
When Henderson walked off air, Sandilands told the audience she was on her “period time”.
In a separate incident in September 2025, Henderson alleges Sandilands made more comments, but they were “dumped” by the censor provided by the network.
“… Just checking in. All OK today?” KIIS’s head of network Derek Bargwanna sent in a text message to Henderson a day after the show.
“Yeah, it’s fine today,” Henderson responded.
“We are getting a lot of complaints from listeners, calling it an abusive relationship, women especially. I can send you though [SIC] some [of] the examples.”
In the statement of claim, Henderson demanded “at least” $82 million in compensation for prematurely ending her 10-year, $100 million contract.
Henderson told she was ‘almost unworkable’
The on-air blow-up came on February 20, when Sandilands accused Henderson of being “off with the fairies” over her interest in astrology and called her “almost unworkable”.
Henderson, who was heard holding back tears, told Sandilands she was offended and that she would never bring up his shortcomings during a live broadcast.Â
She left the studio and did not return.

Henderson alleged in court documents that CBC “did not attempt to intervene and did not otherwise stop” Sandilands.
On March 3, ARN Media announced Henderson had resigned, stating she “cannot continue to work with Mr Kyle Sandilands”.
Henderson later denied that she had quit and was “deeply saddened” by the events and the “possibility of the show ending”.
Sandilands was suspended and issued a breach notice for serious misconduct, with his contract terminated on March 18.
He launched legal action against ARN Media last month over the termination of his $100 million contract.Â
