The chosen research topics cover world-class studies in quantum physics, optical communication, and cybersecurity as well as advancements in Extravehicular Activity on Mars and the Moon.
The list of Australian research to be showcased at IAC 2025 also investigates:
- medical and ethical challenges of sustaining health in spaceflight

“The Indo-Pacific is strategically attractive to our global peers. Such strong representation from Australia speaks to our growing sophistication, influence and ambition as a space nation.
It’s a privilege for SIAA to host this historic Congress featuring Australia’s best thinkers, innovators and achievers. We’re truly shaping the future of sustainable space exploration and resilient Earth solutions in collaboration with worldwide peers and industry innovators,” shares Ms. Vitaris.
