Tuncester, formerly known as Tunstall, is a locality within the City of Lismore local government area in New South Wales, Australia. It lies around 5–7 km (3.1–4.3 mi) outside the main town of Lismore. It is known for its historical self-managed Aboriginal reserve known as Cubawee, which was led by Pastor Frank Roberts for most of its existence (1932–1965).
Tuncester lies on the traditional lands of the Bundjalung people, who inhabited the Richmond River area before European settlers arrived in the 1840s. It was named Tunstall after Tunstall Station, a pastoral lease taken up by amateur naturalist Augustus Adolphus Leycester and his business partner Robert Shaw in 1843, where they grazed cattle. In 1907 Tunstall was officially renamed Tuncester, a combination of Tunstall and Leycester. Leycester Creek runs through Tuncester.
