We speak with Stephen Ward and George Dyke from Symbios Communications about the important role of Earth observation (EO) data in shaping Australia’s space policy and climate response strategies. They explore how satellites support climate monitoring, including detecting and mitigating methane emissions, one of the most potent greenhouse gases, and discuss pathways to achieve cost-neutral solutions.

The conversation delves into the geopolitical challenges of Australia’s reliance on foreign satellite data, the risks posed by shifting global dynamics, and the need to secure data sources through strategic international partnerships. Stephen and George propose key policy recommendations for strengthening Australia’s space capabilities, including the potential for sovereign satellite missions.

They also reflect on the importance of EO data in global climate response mechanisms and the important role satellites play in providing the information needed for climate action and resilience.

In this episode, we explore how space-based technologies are shaping Australia's national security and disaster resilience. Jia-Urnn Lee, Space and Defense Lead at Frontiers SI, joins us to discuss the critical role of Position, Navigation, and Timing (PNT) systems, Australia’s reliance on foreign infrastructure, and the need for national and regional solutions. She also shares insights from her recent policy paper on resilient PNT for disaster response and shares the importance of governance in driving adoption of advanced space technologies.

PNT systems underpin a wide range of essential services, from emergency response and transportation to financial transactions and defense operations. As critical infrastructure, the resilience and accessibility of PNT capabilities are vital for Australia’s ability to respond to natural disasters, maintain national security, and support everyday services.

Vinicius Geudes de Oliveira, a Brazilian lawyer and PhD candidate, explores the legal and cybersecurity challenges facing space infrastructure, particularly in Australia. He explains why cyberattacks are more cost-effective than kinetic warfare and argues for national space policy to protect critical systems.

Vinicius shares how his background in international law led him to pursue a PhD focused on the cybersecurity of Australia’s space infrastructure. He explains that most cyberattacks remain below the threshold of armed conflict but can be just as disruptive, especially in the strategically important space sector. With Australia’s space industry still developing its legal and policy frameworks, he talks about the need for a national space policy and space-specific cybersecurity measures. Vinicius also discusses the importance of international cooperation and advocates for practical tools, like a cybersecurity toolkit, to help space operators better understand and manage evolving threats.
