In this episode of the Contested Ground podcast, Phil Tarrant, Major General (Ret’d) Dr Marcus Thompson and Liam Garman unpack the escalating role of information warfare in today’s conflicts.

From the mobile phone’s transformation into a weapon to the blurred lines between propaganda and “information operations”, the team dissects how truth itself has become contested ground.

The conversation explores the challenges of navigating a “post-truth” world dominated by political tribalism, misinformation, and the weaponisation of narratives. The hosts reflect on conflicts such as Gaza, where competing lobbies and real-time social media footage shape global perceptions.

They also examine Australia’s role within the Five Eyes alliance, including revelations of restricted intelligence sharing around the Ukraine peace talks – a development that could reshape international cooperation and Canberra’s strategic outlook.

The team rounds out the discussion with broader geopolitical and domestic challenges, from US talk of military action in Latin America to Australia’s housing affordability crisis – all underlining the reality that contestation extends far beyond the battlefield.

In this episode of the Contested Ground podcast, Major General (Ret’d) Dr Marcus Thompson, Phil Tarrant and Liam Garman dissect the forces shaping Australia’s national security in an increasingly volatile world.

From the shortage of tradespeople to the sustainability of the nuclear submarine program, the team explores how domestic economic realities – including the property market – intersect with defence capability. 

The conversation turns to the AUKUS arrangement, as Thompson questions whether Australia’s defence budget can support the ambitions of the trilateral pact with the United States and the United Kingdom. The hosts unpack the risks of over-prioritising certain branches of the ADF and debate whether political change would have altered the trajectory of defence spending.

The team then discusses the recognition of Palestinian statehood – with conditions excluding Hamas from governance. They assess the potential impact on relations with Israel – a nation that has long shared intelligence and counter-terrorism support with Australia – and on Canberra’s role in Middle Eastern geopolitics.

The discussion also delves into public sentiment, with Tarrant highlighting the humanitarian toll of the Israeli–Palestinian conflict, and the difficulty of separating moral imperatives from strategic realities.

In this episode of the Contested Ground podcast, Major General (Ret’d) Dr Marcus Thompson and Phil Tarrant are joined by Simon Bergman, CEO of M+C Saatchi World Services, to unpack the evolving landscape of grey zone warfare and the role of creative industries in modern conflict.

Drawing on decades of operational and commercial experience, Bergman explores how advertising expertise is being harnessed to support government information operations: crafting narratives, influencing audiences, and shaping perceptions in the contested information environment.

Thompson and Bergman discuss the cultural and operational divide between government and industry, and how M+C Saatchi World Services is bridging this gap through a hybrid team of former military personnel and creative professionals. Together, they examine how this model can enable faster, more effective responses in the grey zone.

The conversation also turns to the impact of artificial intelligence on information warfare. While acknowledging AI’s ability to enhance speed and reach, Bergman stresses the irreplaceable value of human insight in crafting authentic, effective messaging.

Finally, the team reflects on Australia’s information warfare capability, with Thompson calling for greater investment and deeper collaboration with industry to keep pace with adversaries operating below the threshold of open conflict.

In this episode of the Cyber Uncut podcast, host Liam Garman, editor of Cyber Daily, is joined by Kostas Siourthas, founder and CEO of TomorrowX; Rob Parker, partner at Deloitte; and cyber security leader Dr Marcus Thompson for an in-depth discussion on the future of data protection and innovation in the digital age.

• Siourthas unpacked how Tomorrow X’s data-centric platform enables organisations to apply security policies at the packet level and even add multifactor authentication to legacy systems – a task that was previously resource-heavy and complex.
• Parker elaborates on the limitations of conventional network security in today’s encrypted world, and how TomorrowX’s composable, low-code architecture empowers business analysts to better manage data flows without relying on developers – reducing deployment timelines from months to weeks.
• Thompson shares real-world context around legacy system risk, referencing the recent superannuation credential stuffing attacks, and outlines how TomorrowX provides a cost-effective pathway to modernise outdated systems without full replacement.
• Finally, the trio reflect on what’s next for cyber security, why edge-case vulnerabilities remain one of the industry’s biggest risks, and why now is the time for proactive, data-first strategies.
