Underbool is a town situated on the Mallee Highway in the Sunraysia region. The place by road, is situated about 13 kilometres west from Torrita and 11 kilometres east from Linga. At the 2001 census, Underbool had a population of 223.
The town name is thought to come from the German word underbolt given to it by surveyor Dr Neumayer when he camped there in October, 1861.
The town services the grain farmers and graziers in the area. For tourists, it provides access to the Pink Lakes in Murray-Sunset National Park.
Each of the parks has its own distinctive character and its loyal band of regular visitors, but the Murray Sunset is the best known. Stretching into the north-west corner of the state, it is Victoria’s second largest national park and one of the few remaining semi-arid regions in the world where the environment remains virtually untouched. The name has been inspired by the breath-taking sunsets which, together with the wide open landscapes and starry nights beg the visitor to spend a couple of days paying homage to nature.
