This is part one of a two-part podcast series on WRegSAT Series II.

This podcast features interviews recorded during an April workshop that brought together Australian space experts, featuring Lesley Sutton, Luke Standen, Zamara Rodriguez, Dr Joel Lisk, Dr Melissa De Zwart, Dr Matthew Stubbs, Dr Rebecca Leshinsky, Dr Evie Kendal and Amos Taylor. Through a partnership with Gilbert + Tobin, participants explored gaps in Australia’s space regulatory framework and assessed potential approaches against seven key values:

1. Maa Bullarbu and custodial responsibility for the next seven generations
2. Promoting safe and sustainable practices
3. Encouraging innovation and competitiveness
4. Ensuring national security
5. Including diverse perspectives
6. Meeting international obligations
7. Strengthening regulatory effectiveness and resilience
   

The workshop saw detailed and high-level discussions spanning space regulations together with broader space governance issues among participants. WRegSAT representatives are consolidating these insights into a Regulatory Options Paper. That work will continue through two further workshops in July and November.

Stay tuned for part two of this series. For more information about WRegSAT, please visit our website at https://www.spacegovcentre.org/wregsat.

Welcome to Season Three of Space Matters: The Space Governance Podcast.

This episode serves as a framing discussion for the season and features the opening keynote from founder and CEO of the ACSG, Dr Cassandra Steer, delivered at our expert workshop on space infrastructure in the Asian Century. The workshop, hosted by the ACSG with support from UNSW Canberra, brought together senior stakeholders from government, industry and academia, including a representative from the Philippines Space Agency, to discuss the future of space cooperation in the Asia-Pacific.

Key discussions focused on strengthening regional collaboration, advancing burden-sharing frameworks, addressing evolving security challenges and reflecting on  a changing geopolitical order, including opportunities for Australia’s role in the region. The workshop also considered how these issues intersect with Australia’s regional priorities, including the importance of Asia literacy, and how deeper cooperation can help address national challenges while opening new avenues for engagement across the region.

At a time of increasing strategic competition, these conversations are both timely and necessary. This podcast series builds on ACSG’s commitment to advancing responsible space governance, featuring experts Australian and international experts.
The ACSG thanks Aiden Seaver for his background research for this keynote, together with Mila Spence and Andre Kwok for organising this workshop.

In this episode of Space Matters, we speak with Dr Tristan Moss about the intersection of Australia’s military history and contemporary space policy, tracing how defence considerations have long shaped Australia’s engagement with space. Drawing on historical and policy perspectives, this episodes explores Australia’s approach to developing sovereign space capabilities, recent investments in ground infrastructure and the importance of strategic partnerships in strengthening Australia’s space posture.

The episode also looks at Australia’s space relationships in the Indo-Pacific, highlighting how collaboration with regional partners can enhance stability, support climate resilience, and ensure secure access to important space-derived data. Throughout the discussion, Dr Moss explains the need to mainstream space literacy across government and defence, develop clearer career pathways, and adopt a more integrated, whole-of-government approach to space governance. Dr Tristan Moss reflects that effective leadership, informed policymaking and sustained public engagement are essential to positioning space as a core pillar of Australia’s long-term strategic, environmental and security interests.

We speak with Art Cotterell and learn about why space needs to be mainstreamed across government as a core national priority. Looking on Art’s policy paper, Art's discuss how space technologies underpin critical infrastructure and support major policy domains, including climate change, economic reform and national security. Art sets out the value of a national space task force to coordinate whole-of-government action and highlight the growing importance of intergenerational planning. The conversation also examines the role of the Australian Space Agency in advancing space literacy and building public understanding of how space technologies shape everyday life. Art advocates that public engagement is key to securing long-term political support, and that effective policymaking depends on a government workforce equipped to use and interpret space-based data. Ultimately, they argue that space is far more than rockets and astronauts, and that it is the infrastructure guiding Australia’s economic, environmental and strategic future.Further reading:

In this podcast episode, we talk about the evolving field of space ethics with Flight Sergeant Amy Hestermann-Crane. Together, we discuss how virtue ethics can guide space policy and governance, helping ensure sustainability, responsibility, and security in the cosmos. Amy reflects on her journey into space ethics, the importance of asking ethical questions in space governance, and why moral reflection is important as Australia expands its role in the global space community.

This episode takes a closer look at how ethics play a role at the intersection of sustainability and security in modern space policy. Amy also discusses why Australia needs a dedicated space ethicist within its national framework and how ethics shapes debates concerning the role of multilateral cooperation in advancing global space governance.

In this episode of Space Matters, Dr Cassandra Steer, CEO of the Australasian Centre for Space Governance (ACSG), and Andre Kwok, researcher at ACSG, talk about the role of space in the Asia-Pacific region. Together they reflect on the intersection of space law and policy, technology and international relations, highlighting how collaboration and cultural understanding are essential for shaping the future of space governance.

The conversation touches on the shift from national to regional perspectives, the use of Earth observation data in international law, and the growing role of space diplomacy in fostering cooperation across the region.

They also reflect on the Centre’s new identity, Andre’s journey into space law and Asian studies, and the importance of cultural understanding and language in the Asia-Pacific. Other themes include space law’s role in conflict and security, the potential of space diplomacy to build regional ties and how space can help address shared challenges such as strengthen criminal investigations and climate change response.

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.
