Why Attend

An IAC Down Under, Truly Like No Other

IAC 2025 will serve as a platform for the entire space community to exchange knowledge, present groundbreaking research, and form collaborations that will shape the future of space exploration and innovation. The academic sessions have been carefully curated to challenge conventional thinking and inspire new avenues of inquiry. Together, we can achieve remarkable advancements that will not only propel our space endeavours forward but also inspire the next generation.
In addition to a strong academic program, we are excited to incorporate a strong commercial element to IAC 2025. The congress will facilitate true business partnerships and provide opportunities for start-ups and scale-ups including investor matching.
IAC 2025 will incorporate a Festival of Space for all – so you can enjoy the experience with your friends, colleagues, and your whole family – and make plenty of new friends.
For the first time at an IAC, we are inviting space-enabled industries into the program. These industries include: resources; agriculture; manufacturing; construction; Smart Cities; health; financial services; ICT; utilities; and emergency management. This will not only highlight how space is critical for life on earth but also highlight how space drives our economy.
Very few IACs have been hosted in the Southern Hemisphere, so IAC 2025 aims to advance space in the Indo-Pacific by showcasing the entire region and its wide variety of space-based opportunities, as well as Australia’s rich history of space activities, including above all our First Nations Australians who are recognised as the world’s earliest astronomers.
