Inside Port Phillip Open Water Rated Wreck Dive Site

The Isa (aka Iza) was a wooden, two masted schooner that traded between Melbourne and Geelong from the 1850s. The last located record of this trade is in 1877. The schooner foundered in Corio Bay on 4 June 1871, but was later refloated. The Marine Board Inquiry found charge of wilful damage against the master William Veale, not sustained. William Cowper, a well known lighter agent, and James Balfour were the owners at the time.

The Iza was listed as Powder hulk in 1938 Survey of West Channel (Larkin 1938). In spite of an exhaustive search, no record of the Iza has been located. A wreck of that name appeared on J.P. Larkin's Survey of the West Channel, 1938 and it seems almost certain that he mis-spelt the name. The evidence suggests that the powder hulk was the Isa, which was broken up in 1928 when the register closed and part of the remains used for a powder hulk.

The Isa, which lies in Swan Bay, is significant as one of a few Asian built wrecks in Victorian waters.

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.
