A podcast episode mysteriously deleted by radio host Jackie 'O' Henderson has become a central point in her legal dispute with Australian Radio Network (ARN).

ARN claims Henderson removed an episode of her podcast, "Her Best Life," from February 4, along with all preceding episodes, in late July or early August. In the deleted episode, Henderson and her manager and co-host, Gemma O'Neill, discussed recent "realizations" Henderson had about needing to make significant life decisions, including a potential career change. ARN argues this conversation, released just 16 days before Henderson's public fallout with co-host Kyle Sandilands on February 20, demonstrates she was contemplating a career shift before their professional relationship ended.

ARN further alleges that by February 23, Henderson had decided to pursue work on a different program or at a different time of day. Her legal team subsequently lodged a formal complaint with ARN regarding her treatment and stated she could no longer work with Sandilands, though she remained willing to continue with ARN if an alternative timeslot could be found. ARN's counterclaim asserts that Henderson was attempting to evade her contractual obligations for the breakfast show.

The significance of the deleted podcast episode is amplified by ARN's claim that it was removed after ARN had already referenced its contents in court filings. ARN is requesting the Federal Court consider the removal of the episode as an "admission" that the material was either damaging to Henderson's case or directly relevant to it.

The legal battle stems from Henderson's broadcasting contract, which ARN terminated on March 3. Henderson is suing ARN, while the company has filed a counterclaim, alleging that Henderson and her company failed to provide the contracted services.

In parallel developments reported Tuesday, Henderson's doctor has diagnosed her with post-traumatic stress disorder (PTSD), which she attributes to her working relationship with Sandilands. Medical documents filed with the Federal Court detail this diagnosis by Dr. Jonathan Phillips, who cited "ongoing bullying perpetrated by Sandilands" and "the failure of ARN to offer appropriate care and protection."

Henderson, in a sworn statement, described being "belittled" and "humiliated" by Sandilands, whom she characterized as "unpredictable and erratic." She stated that his constant criticism and "putting me down at work" wore her down, leading to feelings of exhaustion and a desire to give up, describing the treatment as subtle but regular, and akin to bullying. She noted that this treatment intensified from 2023 onwards, causing her anxiety and a persistent sense of dread, even during outwardly positive periods in their working relationship, making her feel emotionally unsafe.

The Federal Court has not yet ruled on the allegations presented by either party.

On Tuesday it was reported that Henderson's doctor has diagnosed her with post traumatic stress disorder as a result of working with Sandilands
