For the River, see River Mersey.
The Mersey was a ship wrecked in the Torres Strait, Australia about mid-June 1804.
The Mersey was built in Chittagong, Bangladesh in 1801 and registered at Fort William, India. It was 350 tons and carried 10 guns (cannon). It was owned and captained by James Wilson. The ship had been chartered by Governor Philip Gidley King to purchase 250 cows from Bengal and deliver them to Hobart, Tasmania. The Mersey sailed from Port Jackson on 24 May 1804 with a cargo of timber for Bengal. While passing through the Torres Strait, the Mersey was totally wrecked. Only 17 crew and the Captain were saved by sailing in a longboat to Timor; 56 others drowned. After refitting the longboat at Dili they reached Bencoolen from where they sailed to Madras on an Acheen vessel. Captain Wilson arrived in Calcutta 20 September 1804 on board the Margaret, from Madras.
