‘Sustainable Space : Resilient Earth’, the guiding theme of IAC 2025 Sydney, explores the essential connection between space innovation and sustainability, focusing on three central areas: space-based applications for Earth; sustainable space activities; and sustaining life beyond Earth.

In alignment with its commitment to space sustainability, Australia as a founding member of the United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) is closely involved in the development and implementation of international norms for safe, stable, and sustainable space activities. Australia’s IAC 2025 provides a platform to promote global cooperation and responsibility in shaping the future of space exploration. IAC 2025 in Sydney will showcase Australia’s innovations in space and reinforce the importance of collaboration across the Indo-Pacific region to ensure a sustainable and resilient future for Earth and beyond.
