The Great Western Tiers (Palawa kani: Kooparoona Niara) are a collection of mountain bluffs that form the northern edge of the Central Highlands plateau in Tasmania, Australia. The bluffs are contained within the Tasmanian Wilderness World Heritage Site.
The bluffs stretch northwest to southeast over 100 kilometres (62 mi) from the 1,420-metre (4,660 ft) Western Bluff near the town of Mole Creek to the 1,210-metre (3,970 ft) Millers Bluff, approximately 25 kilometres (16 mi) west of Campbell Town.[5] During the late 19th century the Tiers were known as the Great Western Range.[6]
