After a notable 22-year tenure, Jackie Henderson has bid farewell to the Kyle and Jackie O Show. Her departure follows a heated on-air exchange with co-host Kyle Sandilands during the broadcast on February 20.

In a related development, ARN Media revealed today that Sandilands faces potential termination unless he can demonstrate within 14 days that he did not violate his contract, stemming from allegations of “serious misconduct” during the controversial episode.

Henderson has been absent from work since the incident and has yet to comment publicly on the matter.

In a statement, ARN Media said: “Ms. Jacqueline Henderson has informed us that she ‘cannot continue to work with Mr. Kyle Sandilands’.

“As a result, ARN has ended its services agreement with Henderson Media Pty Ltd, which allowed Ms. Henderson to host the Kyle and Jackie O Show. Consequently, Ms. Henderson will no longer be part of the show.

“ARN has extended an offer to Ms. Henderson for a potential new show within the ARN network. Additionally, ARN has issued a formal notice to Mr. Kyle Sandilands and Quasar Media Services Pty Ltd (Quasar Media), indicating that Mr. Sandilands’ conduct on the February 20, 2026, episode is considered a serious misconduct breach of ARN’s agreement with Quasar Media, through which Mr. Sandilands hosts the Kyle and Jackie O Show.”

“Mr Sandilands has been given 14 days to remedy this breach. If it is not remedied, ARN will terminate the services agreement with Quasar Media, and in that event Mr Sandilands will cease to present the Kyle and Jackie O show.

“During the 14 day period, Mr Sandilands will not take part in the show. The KIIS breakfast show will be taken off-air effective immediately, with interim arrangements made for the show.”

This week marked the second week off-air for Henderson, following the February 20 broadcast that ended in tears after Sandilands called out her work ethic and teased her “obsession” with astrology.

The on-air fight began after Jackie O read from Andrew Mountbatten-Windsor’s astrology birth chart and Sandilands complained about her interest in astrology charts.

“Your fixation on this has made you almost unworkable,” Sandilands told her.

“You are off with the fairies with this s–t, it’s mental.”

He claimed her fixation on astrology charts made her sound like a “drug addict”.

Henderson has previously opened up on air about addiction issues that led to her going to rehabilitation in the US in 2022.

Henderson said Sandiland’s accusations were “so unfair” and that he was attacking her on air.

“I would never say things like that about you,” she said.

“It’s a total attack, it really is. Kyle, to say ‘you don’t know what the F is going on, you’re not doing your job,’ that’s an attack and I wouldn’t do that.”

Sandilands and Henderson have been in an on air partnership for 27 years.

They moved to breakfast in 2005 and then to KIIS in 2014.

Then have been under contract in a lucrative $200m 10-year deal that was set to run until December 2034.
