The town of Ouyen is located just over 100 kilometres south of Mildura in the far north-west of Victoria.
Ouyen is situated within a vast area of wheat fields and sheep grazing land. Wheat loading facilities and massive grain silos are a feature of the town, located along the railway line. The Big Mallee Root, located on the Calder Highway, is the the largest Mallee stump in Australia and serves as a tribute to early settlers who cleared the land of drought-resistant eucalypt trees to make way for agricultural activities.
The commercial centre of Ouyen is located in Oke Street and includes the council offices and the Local History Research Centre which houses a collection of books and historical records in the old court house.
Ouyen is located in the heart of the vast national parks of the Mallee region. To the south-west is the Wyperfeld National Park with its network of lake beds. In the north-west is the Murray-Sunset National Park, characterized by its wide open landscapes and isolation. And to the north is the Hattah-Kulkyne National Park which borders the Murray River and features native woodlands and lakes.
