A legal battle between Jackie "O" Henderson and ARN Media appears still headed for an October trial after her former co-host Kyle Sandilands settled his own court case against the company.

The media company behind Kiis FM will be forced to pay around $5 million a year until 2028 to avoid costly and drawn-out litigation with its former star host.

The controversial broadcaster had been seeking up to $85 million, arguing the radio network had improperly torn up his decade-long contract.
