Australian authorities are investigating the origins of six solid silver spheres that washed up on Forrest Beach near Townsville in northern Queensland this weekend.

Officials believe the objects are likely space debris, and the Australian Space Agency (ASA) is working to determine which vehicle could have shed them. Police and fire crews, wearing protective gear, placed the spheres in hazardous‑material barrels for secure transport, while a 50‑metre exclusion zone remained in place to keep residents away.

Officials warned the public that the items might contain hazardous substances. Queensland Fire Department repeatedly urged anyone who finds a suspicious object to move away, call emergency services, and avoid touching the spheres.

Online chatter suggests the objects might be remaining propellant tanks—perhaps from a fuel system used in a rocket—containing flammable or reactive chemicals such as hydrazine. However, the specific launch vehicle or mission has not yet been identified.

This is not the first time mysterious extraterrestrial‑style objects have shown up on Australian shores. In 2023, a large metal dome found on a Western Australian beach was traced back to one of India’s Polar Satellite Launch Vehicles (PSLV). In 2011, a similar sphere discovered in Namibia’s grasslands was thought to be a hydrazine fuel bladder from an unmanned rocket.
