Quambatook is a town in northern Victoria, Australia. The town is located on the Avoca River in the Gannawarra Shire Local Government Area, 302 kilometres from the state capital, Melbourne.
At the 2001 census, Quambatook had a population of 245.
Quambatook was settled following the end of the Victorian gold rush of the 1850s. Resumption of large squatter’s land holdings for closer settlement in the 1870s lead to Quambatook becoming one of Victoria’s leading wheat and sheep producing areas.
Quambatook has been recognised as the tractor pulling capital of Australia with an annual competition held at Easter since 1976. The town is the birthplace of country music performer John Williamson.
