Andy Nguyen is a network engineer by day. But in his spare time he delves into "the balloon scene" where he gets to indulge his love of amateur radio.

He makes the tiny electronics that accompany the helium-filled party balloons he launches more than 9000 metres into the air. And he's just recorded a record run.

A standard silver party balloon he launched from a Williamstown park on May 23 ended up spending eight weeks travelling the globe at high altitude, clocking up more than 110,800 kilometres.

"I don't think that's been done before with a party balloon," he said. "They usually do one circumnavigation. Two was a bonus but then this one just kept going."
