Mystery sub spotted 100m off Coast beach

A MYSTERY submarine has been spotted about 100m off the coast this morning by an eagle-eyed local photographer.

Cade Mooney snapped the sub from his balcony about 6.30am, as it powered south.

He was looking out over Bulcock Beach and the Pumicestone Passage when he said the sub just "popped up".

The experienced photographer said it looked like a Collins Class submarine to him.

The Collins Class is a fleet of six, diesel-electric Australian-built submarines.

He said he'd been out in the area with the Caloundra Coast Guard a few years ago when a US Navy submarine surfaced nearby as well.

The Daily has approached the Department of Defence for more information about the submarine.
