Southern Cross Austereo is appealing against a licence condition imposed on it by the media watchdog following offensive comments made by shock jock Kyle Sandilands.
Sandilands called a female journalist a "fat slag" and threatened to "hunt her down" on his 2Day FM radio segment, The Kyle and Jackie O Show, in November last year.
Following an investigation, the Australian Communications and Media Authority (ACMA) found the remarks were grossly demeaning and weretargeted vitriol that breached commercial codes.
It imposed stricter licence conditions on the station in May, prohibiting the broadcast of any content that "offends generally accepted standards of decency".
Southern Cross Austereo (SCA), 2Day FM's parent company, on Wednesday confirmed it had filed an application with the Administrative Appeals Tribunal (ATT) over the licence requirement, which stands for five years and applies to the entire station.
SCA CEO Rhys Holleran described the ruling as "broad reaching and its lengthy term unprecedented".
"SCA believes ACMA has not fully taken into consideration the extensive processes and procedures that the business has taken upon itself to implement with regards to comments made by Kyle Sandilands," he said on Thursday.
The media watchdog said on its website that it would contest the application.
"The condition imposed by the ACMA will continue to have effect pending any decision by the AAT," the website said.
Sandilands' remarks prompted several sponsors and advertisers - including Jenny Craig, Coles, Bunnings and Vodafone - to withdraw their support from 2Day FM.
