The 76th International Astronautical Congress will see the world’s space community gather to access the latest advancements and trends, academic works, industry connections, and partnership opportunities. IAC 2025 is hosted by Space Industry Association of Australia (SIAA) and co-hosted by Australian Space Agency and the NSW Government.

The 76th IAC in Sydney in 2025 presents a generational opportunity to showcase the rapid progress of Australia’s space industry and the importance of space-enabled services to the Australian way of life. The event will delve into why space is critical for both businesses and our everyday lives, with the aim of advancing space in the Indo-Pacific by showcasing the entire region and its wide variety of space-based opportunities.

‘Sustainable Space: Resilient Earth’, the guiding theme of IAC 2025, 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.
