Siobhán McKenna And The Murdoch Connection You Might Not Know
How Siobhán McKenna's career intersected with Murdoch
Siobhán McKenna became closely linked to the Murdoch empire through her long partnership with Lachlan Murdoch, first as a private business ally and later as a senior executive inside News Corp's Australian media operations. Their relationship mattered because McKenna was not simply a boardroom name; she helped shape investments, broadcasting strategy, and corporate succession dynamics around one of the world's most powerful media families.
What the connection was
The Murdoch connection is best understood as a professional and strategic alliance, not a family tie. McKenna and Lachlan Murdoch co-founded the private investment firm Illyria in 2005, and she later became one of his most trusted advisers in Australia, helping steer decisions across radio, pay TV, and news businesses.
That alliance expanded after Lachlan Murdoch's return to Australia in July 2005, when McKenna was already part of his inner circle from earlier personal and professional contacts in the 1990s, including a friendship formed through his then partner, Kate Harbin Clammer. The result was a durable working relationship that placed McKenna near the center of Murdoch-aligned media assets for nearly two decades.
Career timeline
Career milestones show how her path moved from public policy and consulting into one of Australia's most prominent media power structures. McKenna worked at McKinsey & Company, served as a Commissioner of the Australian Productivity Commission, and then moved into board and executive roles tied to Murdoch-backed and Murdoch-controlled entities.
| Date | Role or event | Why it mattered |
|---|---|---|
| Early 1990s | Met Lachlan Murdoch through social and personal circles | Established the relationship that later became a long-running business alliance |
| 2005 | Co-founded Illyria with Lachlan Murdoch | Created a private investment platform tied to media and telecommunications ventures |
| 2010-2017 | Board involvement with Ten Network Holdings | Placed her inside a major, high-risk Murdoch-linked investment that later collapsed into administration |
| 2014 onward | Led News Corp broadcasting in Australia | Made her a core executive in Foxtel, Sky News, Fox Sports, and related assets |
| December 2022 | Appointed Chair of Australia Post | Showed her influence had expanded beyond Murdoch companies into national public-sector governance |
| 2025 | Departed News Corp after the Foxtel sale to DAZN | Marked the end of a major Murdoch-era chapter in her career |
Why Murdoch valued her
Trusted operator is the phrase that best captures McKenna's value inside the Murdoch orbit. She brought a rare mix of strategy, government experience, and commercial judgment, which is why she was trusted not only with investments but also with sensitive governance and succession issues.
News Corp and related reports described her as a key force behind the transformation of Foxtel and Sky News Australia, with Robert Thomson saying her departure was "epochal" and that she had been a "transformational force" during her years at the company. Those kinds of comments suggest McKenna was seen as more than a manager; she was part of the executive glue holding together several moving pieces in the Murdoch media network.
"Her decision, and it is her decision, is essentially epochal as Siobhan has been a transformational force during her years with News Corp," Robert Thomson said in 2025.
Business ventures with Murdoch
Illyria was the most direct shared venture between McKenna and Lachlan Murdoch. The firm became associated with media investments such as Nova Entertainment, and their collaboration also extended to the troubled Ten Network investment, which ultimately failed after entering voluntary administration in 2017.
McKenna later became a central executive in News Corp's broadcasting stack, serving as chairman or executive chairman across entities including Foxtel, Fox Sports, Australian News Channel, and the broader broadcasting portfolio. In practical terms, that meant she helped manage the commercial logic of pay TV and news distribution at a time when streaming, platform fragmentation, and changing audience habits were reshaping the industry.
- Illyria linked McKenna and Lachlan Murdoch in private investing.
- Ten Network became the most visible setback in that shared investment era.
- Foxtel and Sky News became the most successful parts of her Murdoch-era executive profile.
- Her appointment to Australia Post showed her profile extended beyond media into broader corporate governance.
Governance and public roles
Public appointment matters here because it showed McKenna's reputation was not limited to News Corp circles. The Australian Government appointed her Chair of Australia Post in December 2022 for a three-year term beginning that month, citing her commercial, strategic, digital, technology, and government-relations experience.
That appointment was notable because it came while she was still deeply associated with Murdoch-linked businesses, including News Corp broadcasting, Foxtel, and Sky News Australia. Supporters saw that as evidence of a high-caliber executive profile; critics saw it as proof of how thoroughly Murdoch-adjacent she had become.
How the relationship evolved
Relationship shift became visible in 2025 after the sale of Foxtel Group to DAZN. Once that transaction reduced the strategic importance of News Corp's broadcasting arm, McKenna's role was diminished and her departure from News Corp was announced for the end of the year.
That transition also reflected a broader realignment in media ownership, where streaming economics and portfolio simplification forced traditional broadcasters to rethink leadership structures. McKenna's exit, therefore, was not just a personnel change; it was a sign that the Murdoch media architecture she had helped build was entering a new phase.
