New tech risks forces Australia to rework satellite strategy

Australia has scrapped plans for a large defense satellite project, opting instead for a network of smaller micro-satellites due to emerging anti-satellite threats. Defense Minister Richard Marles explained that advancements in technology now enable adversaries to target and destroy satellites, making Australia’s initial plan for a few large satellites outdated. Originally developed in collaboration with Lockheed Martin, the high-cost Geostationary Earth Orbit system was designed to enhance communications over the Indo-Pacific region.

Marles pointed to distributed micro-satellite networks, like Starlink’s use in the Ukraine conflict, as a more resilient and cost-effective alternative. A “mesh-type” network of satellites could provide more reliable defense communications with increased survivability against attacks. This shift reflects a strategic pivot to distributed technology that reduces vulnerability while enhancing adaptability.

The shift underscores Australia’s commitment to bolstering defense communications against emerging threats. The government is exploring a system of micro-satellites that not only strengthens operational resilience but also demonstrates Australia’s alignment with global shifts toward decentralised space technology.
