Explosives experts say a metal object found on a remote north Queensland beach isn’t a WWII bomb as first suspected.

A suspected World War II bomb found on a north Queensland beach has turned out to be an unidentifiable hollow metal object.

Military explosives experts spent Thursday trying to figure out what the object was after a passer-by called police saying they’d stumbled across what they believed was a bomb.

But it’s actually a “hollow spherical metal object” that’s not of military origin, a Department of Defence spokesman says.

“While on site, the team cut the object open to show that it was empty and posed no threat to public safety,” he said.

The object, found at Kangaroo Creek, south of Bowen, had likely been in the area for some time and may have been uncovered during Cyclone Ita last month.

Although it turned out to be harmless, the spokesman says anyone who stumbles across anything that may be a bomb should contact police.

The object has been left on the beach.
