Estramina, originally called Extremeña, a two-masted schooner of 102 tons, was built at Guayaquil, in the Spanish Viceroyalty of Peru, now in modern-day Ecuador, and launched on 13 October 1803.

[2] On 1 October 1804 it was seized from port of Caldera in Copiapo Bay, Chile, by the armed merchant brig Harrington, Captain William Campbell, and sailed across the Pacific into Australian waters.

The Governor of New South Wales, Captain Philip Gidley King RN (1800–06), hearing the Spanish vessel was hiding in Jervis Bay, ordered it to be escorted to Sydney where it was detained pending instructions from the Secretary of State for War and the Colonies in London.

[4] The Governor also reported the event to William Marsden, First Secretary to the Admiralty (1804-1807), stating that Extremeña had been under the command of Don Antonio José del Campo, which was not correct.

The fate of Estramina was reported by the Commandant at Newcastle, New South Wales, Australia, on Friday 19 January 1816, as the vessel was beating out of the harbour with a strong north-east wind and ebb tide, she was obliged to come to anchor, which parted, and she drifted onto a sand bank, then broke up.
