The six mysterious objects were found by the public washed ashore in the Forrest Beach area, north of Townsville, on Friday, Saturday and Sunday and were suspected of containing hazardous chemicals. One expert said the objects were likely “space balls” – pressurised balls of fuel and one of the most common types of space debris to fall to Earth after a rocket launch. Police and fire authorities examined the debris and enforced 50-metre exclusion zones around the objects at the weekend. The space agency said the recovered objects “appear to be pressure vessels from a space launch vehicle”.

The objects’ location and characteristics are consistent with debris from a foreign rocket body that recently re-entered the atmosphere from orbit.” The agency said it was “continuing to engage with international authorities to formally confirm the launch vehicle and launching state.” The Guardian has requested further information. Associate Prof Alice Gorman, a space archaeologist and space junk expert at Flinders University, said space debris that falls back to Earth can be governed by the 1967 United Nations Outer Space Treaty , to which Australia is a signatory. “It’s the most widely accepted space treaty where the launching state retains ownership of the launch material. This means the nation that launched them owns those pressure vessels,” she said. “Australia then has to enter into negotiations with the launching state. The launching state will say if they want them back or not.” She said when part of an old Indian rocket washed ashore in Western Australia in 2023 , the Indian government did not request the material. Gorman said a pressure vessel is used to store fuel before it is forced out into the rocket engine itself. They are made of titanium alloy and can survive at very high temperatures. The fact they survived did not necessarily indicate anything had gone wrong in a rocket launch, she said. “Part of Australia’s responsibility is to negotiate for the return of the space ball
