The name Tirroan comes from the title of the first British pastoral property set up in the region, which was established by Gregory Blaxland Jnr and William Forster in 1848.[4] It is possible that it is derived from the name of an Aboriginal stockman on this run, who later died of tuberculosis in 1880.[2] The town itself was initially known as West Albany but the name was changed on 3 August 1899.[2][5]
