Shock Split: Jackie ‘O’ Henderson Quits ‘Kyle and Jackie O Show’ After Explosive On-Air Feud with Kyle Sandilands

By Entertainment Staff Sydney, March 4, 2026 — Australia’s longest-running and most controversial breakfast radio partnership has dramatically ended. Jackie “O” Henderson has officially departed The Kyle and Jackie O Show on KIIS FM after more than 25 years alongside co-host Kyle Sandilands. The split follows a heated on-air argument on February 20, 2026, during which Sandilands berated Henderson, prompting her to walk out and take extended leave.

ARN Media, parent company of KIIS FM, confirmed the news in an ASX announcement late Tuesday: “Ms Jacqueline Henderson has given notice that she ‘cannot continue to work with Mr Kyle Sandilands.'” Henderson’s services agreement was terminated, and the show was taken off-air effective immediately. ARN accused Sandilands of “serious misconduct” in breach of his contract, suspending him for 14 days and giving him that period to remedy the issue or face termination.

The feud erupted during a live broadcast when Sandilands criticized Henderson’s focus, reportedly calling her “unfocused” and “off with the fairies” amid discussions involving astrology. Henderson appeared visibly upset, left the studio in tears, and did not return. Sandilands initially downplayed the incident, telling listeners she needed time to “gather her thoughts” and would be back soon. However, her absence stretched, and tensions escalated behind the scenes.

Sydney’s Kyle and Jackie O Show canned after on-air spat

The duo, often dubbed the benchmark for Australian breakfast radio, commanded massive audiences and lucrative deals. Their 2023 contract renewal reportedly worth $200 million over 10 years made them among the highest-paid talents in the country. Despite frequent controversies—including ACMA findings over vulgar content—the show dominated ratings in Sydney and beyond.

Henderson, who credits Sandilands and the show for her rise, has maintained a close friendship with him for decades. In recent comments on rival radio, Nova FM’s Tim “Fitzy” Ryan expressed sympathy for the production team: “They’ve got 15-plus people on the floor today that might be in the building saying, ‘What do we do now?’ Our thoughts are with those guys.” Co-host Cat Lynch added that support staff, unlike the high-profile hosts, face uncertainty without massive contracts.

ARN has offered Henderson her own program within the network, signaling potential for her continued presence on KIIS. Interim arrangements are being made for the breakfast slot, with Kent “Smallzy” Small addressing listeners Wednesday morning: “We’ve got some important news… Jackie has now officially left the show.”

Industry insiders note the split was not engineered by ARN to escape financial burdens, though some staff reportedly felt “overjoyed” by the implosion given past tensions. Former colleagues suggest underlying issues built off-air, beyond the February 20 tirade described as “mean and nasty.”

Public reaction has been swift. Many expressed relief with one-word responses like “Finally,” citing years of controversial segments. Others lamented the end of an era, praising the show’s entertainment value despite its edge. Henderson has not publicly commented since the announcement, while Sandilands remains off-air.

The fallout raises questions about the future of Australian breakfast radio. With no immediate replacement duo announced, KIIS faces the challenge of filling a high-profile, high-ratings void. ARN emphasized support for staff and listeners during the transition.
