Meet the site
The Cumberland is one of the oldest wreck sites on the South West coast. Marinelife.org.au describes a 444-ton wooden colonial trader, on passage from Newcastle, New South Wales, to Fremantle, that was lost on a sandbank south of Cape Hamelin with no loss of life. Divers found the wreck in 1981. An anchor, a cannon and timbers remain, but the weedy bottom makes the relics hard to see, and material recovered from the site is displayed in the Augusta museum.
The source lists the vessel with the date 1829; the loss appears to have occurred in the early years of the Swan River Colony (founded 1829), which makes it one of the earliest colonial-era wrecks in Western Australia. The date should be confirmed against the WA Museum shipwreck database before publication.
This is a site for wreck-history enthusiasts with a boat and local knowledge. In 3-8 m of water it is technically easy, but finding the remains in weed requires patience. Like all wrecks older than 75 years it is protected under heritage legislation; nothing should be moved or taken.
Combine it with a visit to the Augusta museum to see what came from the site.
Hamelin Bay was a timber port from the 1880s, when a jetty built in 1882 and extended in 1898 served M. C. Davies' milling operations. It was notorious for wrecks in bad weather because it is exposed to the north-west gales of winter storms; the 22 July 1900 storm alone wrecked several ships, and only the old jetty piles remain today. The bay is now a recreation zone in the Ngari Capes Marine Park, and every wreck in it older than 75 years is protected.
