Wreck Dive | Boat access
Level: Open Water and beyond.
The Formosa (aka SS Formosa) was a combination iron hulled coaster, three-masted schooner and twin screw steamer, built in 1868. The Formosa lies at the Portsea Back Beach in Bass Strait, 3 miles east of Point Nepean,
The Formosa shipwreck is shattered and spread over numerous gutters. The boilers and winches are still identifiable. It is often difficult to find when shifting sands cover its remains.
The Formosa shipwreck is on an extremely rough section of Point Nepean, plus difficult to dive. The wreck can only be dived in ideal conditions.
Back Beach Warning: Always keep an eye on sea conditions throughout any dive on the Back Beaches of the Mornington Peninsula. Please read the warnings on the web page diving-the-back-beaches before diving or snorkelling this site.
Bass Strait Warning: Always keep an eye on sea conditions throughout any shore or boat dive in Bass Strait on Victoria's coastline. Please read the warnings on the web page diving-in-bass-strait before diving or snorkelling this site.
The Formosa was a twin steam engine, twin screw steamer, built in 1868, by Thomas B Seath & Co, Rutherglen, Glasgow. Gross Tonnage: 205, Net Tonnage: 173. Built on the dimensions of 137 ft (42 m) in length, with beam: 22.2 ft (6.77 m), and draught 8.33 ft (2.54 m).
The Formosa sailed on its maiden voyage from Clyde, Glasgow for Melbourne rigged as an auxiliary three-masted schooner with cargo of bottled ale, cast-iron pipes and general. Wrecked at Port Phillip Heads on 5 February 1869. The captain and pilots were both found to be at fault by a Board of Inquiry.
The Formosa is historically significant as a rare Australian example of the technical innovation of Thomas B. Seath's shipbuilding. The vessel has interpretive significance as an example of Rutherglen shipbuilding techniques and a historic shipwreck site. The archaeological significance still needs to be determined, however, there is potential for significant wreck remains to reveal further aspects of Seath's technical innovations and social life aboard vessels such as these.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.
The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
