Former Sydney radio broadcaster Jackie “O” Henderson has filed legal action against employer ARN Media, following the collapse of the hit Kyle and Jackie O Show.

In a statement to the ASX, ARN Media confirmed Henderson had commenced legal action over her contract termination and was claiming at least $82 million in compensation.

The Kyle and Jackie O Show, broadcast on ARN Media-owned KIIS FM, came to an abrupt end last month after an on-air row between Henderson and co-host Kyle Sandilands.

Sandilands was taken off-air and later sacked, with the ex-radio star subsequently launching wrongful termination claims against ARN Media.

In a statement, ARN Media said Henderson sent a letter that “made psychosocial health and safety and bullying complaints in relation to the conduct of Mr Sandilands” following the February 20 on-air row.

ARN Media alleged the letter “involved the exercise or proposal to exercise workplace rights, and that the contract was terminated because of that exercise or proposed exercise”.

The network said Henderson was claiming compensation “of at least $82,250,000”.

“ARN disputes the claims. It intends to defend the proceedings,” the network said in its statement.

It comes as Sandilands fronted the Federal Court in Sydney for the first time last week, telling reporters the termination of his $100 million contract had been “traumatic”.

He denied allegations of misconduct and said his priority was to return to radio.

“I want to get back to work as quick as possible. I’ve got a family to support,” he said on Friday.

A judge provisionally reserved five hearing days in June for Sandilands’s matter.

A Sydney-based employment lawyer says the network who owns radio station KIIS FM acted “prematurely” when it cancelled the controversial Kyle and Jackie O Show.

Sandilands and Henderson had been due to remain on air until at least 2034 as part of a combined $200 million contract with ARN Media.

The pair had worked together for more than 25 years.

Sandilands said he had not been able to speak to Henderson since his suspension.

Henderson previously said she was “deeply saddened” by the demise of the radio show.

Henderson has been contacted for comment.
