Full title reads: "Sydney, Australia. A new World's Record - in deep sea diving. Wonderful new diving suit enables diver to descend 170 feet - stay there an hour & rise in 3 mins - unharmed. Look & listen closely!"

Sydney, Australia.

A man in a deep sea diving suit climbs over the edge of a boat. The suit was designed by A R Clifford and J Cantock (?). Diver Lock moves himself away from the boat on a rope and then begins to descend - to the deepest part of Sydney Harbour. Bubbles rise from where he has gone down.

Sound track has what purports to be a conversation between the ship and the diver.

A bag is sent down from the ship on a rope - it disappears under the water.

Men on the ship turn the handles of a machine - either a winch or the air supply pump.

The bag is hauled back up and men on the ship check its contents.

The diver now rises to the surface and is help back on board.
