this site is for historic info. The database if quite good and easy to use. Please note when dealing with any relics:
Australia protects its shipwrecks and their associated relics that are older than 75 years through the Historic Shipwrecks Act 1976. The Historic Shipwrecks Act applies to Australian waters that extend from the low tide mark to the end of the continental shelf and is administered in collaboration between the Commonwealth and the States, Northern Territory and Norfolk Island. Some Australian shipwreck sites lie within protected or no-entry zones. (no entry zones also include ships that are designated as war Graves)
I am not sure if that's 75 years from 1976, or 75 years from the date of the wreck irrespective of year.
