Sustainable Space : Resilient Earth

This prestigious event is where the world’s space community gathers to access the latest advancements and trends, academic works, industry connections, and partnership opportunities.

IAC 2025 in Sydney is hosted by Space Industry Association of Australia (SIAA) and co-hosted by Australian Space Agency and NSW Government.

This will be the third time Australia has hosted the IAC, with previous events held in Melbourne in 1998 and Adelaide in 2017. 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 highlight Australia’s commitment to learning from indigenous knowledges and collaborating with First Nations communities on the deployment and use of space technologies.

The event will broaden the influence and relevance of space to adjacent industries, including emergency services, health, utilities, telecommunications, resources, manufacturing, finance, construction, agriculture, and Smart Cities. It will delve into why space is critical for both businesses and our everyday lives.

IAC 2025 aims to advance space in the Indo-Pacific by showcasing the entire region and its wide variety of space-based opportunities.
