45-kg bomb out to sea by Australian navy ship tows unexploded

45-kg bomb out to sea by Australian navy ship tows unexploded:
Australian navy divers have removed an unexploded 45-kilogram bomb on a reef off the southeastern coast and a ship towed it to deeper waters because it posed a significant risk to the public.

The bomb was found by a fisherman on Elizabeth Reef near Lord Howe Island, about 550 kilometers off New South Wales state. He photographed his discovery and reported it to authorities.

Divers aboard the HMAS Adelaide carefully removed the abandoned explosive by floating it to the surface and towing it farther out to sea where it was dropped into 550-meter deep waters.

“That depth is really safe. It’s not going to ever get washed back up onto the reef,” Senior Marine Parks Officer John Pritchard said.

There’s no deep-sea fishing or trawling allowed out there. It’s a recreational fishing zone only. The chances of that UXO (unexploded ordinance) ever coming back to the surface is negligible.

The origin of the bomb is not known and divers couldn’t estimate its age because of its deterioration, a spokesperson for Environment Minister Sussan Ley said.

Bombs of that size were used as long ago as World War I, sometimes dropped from aircraft to target submarines. There were also bombings off the Australian east coast during World War II.

Ms. Ley said the fisherman and navy divers had potentially saved lives and one of Australia’s most important reefs.

The device was regarded as live by the navy and the consequences could have been quite frightening, Ms. Ley said in a statement on Sunday. “Thankfully the reef’s precious ecosystem is safe and most importantly so are future visitors.”

Elizabeth Reef is about 160 kilometers north of World Heritage-listed Lord Howe Island. Along with nearby Middleton Reef, Mr. Pritchard said it is the southernmost coral reef platform in the world.

There’s been 125 corals identified there and over 300 species of fish, Mr. Pritchard said. It’s quite a unique environment and, because it’s so far from anywhere, it’s relatively untouched.
