About Olive Cam
The Olive Cam was built in 1920 as the steam trawler SS Nodzu by Cook, Welton and Gemmell of Beverley, England: 128.5 feet long, 23.5 feet wide and 281 gross tons, with a coal-fired triple-expansion engine. In 1929 she was bought by Cam and Sons, the Sydney fishing company founded by Italian-born Carlo Caminiti, and later renamed Olive Cam after one of his children. During the Second World War she was requisitioned as the auxiliary minesweeper HMAS Olive Cam (FY76), nicknamed 'Little Ol', served off Western Australia and took part in the search for survivors of HMAS Sydney in 1941. She returned to trawling in 1946.
On 2 November 1954, fishing between Eden and Green Cape under Captain William Glackin, she was caught in a howling south-westerly. Trying to reach Eden close to shore, she struck a bommie just south of Mowarry Point and lost her propeller. As the crew tried to get ashore along a line, huge waves swept away Captain Glackin and two others; they died. The survivors walked towards Eden and reached the Edrom guest house.
Today the Olive Cam lies in less than 9 m, with many pieces in only 3 m, in three gullies south of a small point. In the southern gully are a length of drive shaft, copper pipe, brass fittings, the remains of the rudder and one and a half cylinders of the engine, and the boiler standing on end like a huge rock almost to the surface, with a winch beyond. The middle gully holds a great deal of wreckage up to 3 m, and outside it lies a Lt Rodgers anchor. McFadyen says a keen wreck diver could spend well over an hour here.

Getting there & entry
Remains of a steam trawler and former WWII auxiliary minesweeper wrecked in 1954 just south of Mowarry Point, south of Eden; boiler, engine parts and anchor in gullies at 3–9 m.
Boat access only, in millpond seas. From Eden run south past Red Point and Mowarry Point, about 20 minutes. McFadyen's position (37°09'02"S 150°00'24"E, AUS66 datum) puts you a few metres south of a small unnamed point off three gullies; the main wreckage is in the middle gully and more in the southern gully.
Anchor in about 12 m.
Entry: Giant stride from boat anchored in about 12 m
Facilities: Quarantine Bay ramp and Snug Cove, Eden.
Weather, swell & tides
McFadyen says you need millpond seas, with westerly or south/south-easterly winds preferable; the gullies face the open sea and surge badly in any easterly swell. Many pieces are in only 3 m, where surge is strongest. Check the swell forecast and look at the gullies from the boat before committing; if waves are breaking at their heads, dive elsewhere, such as the tugs off Red Point.
Best season: Calm westerly or south/south-easterly days

How the dive is usually run
From the anchor swim into the southern gully: drive shaft, copper pipe, brass fittings, rudder remains and one and a half engine cylinders, then the boiler standing on end, then a winch. Return along the gully's north side, follow the wall north into the middle gully with its heavy wreckage up to 3 m, and on exit turn left to find a Lt Rodgers anchor.
