Our region

Our region extends over 23,500 square kilometres and covers a total population of 100,400.

Located in south-west Victoria, it extends from the Otway Ranges to the South Australian border. It includes the major centres of Warrnambool, Portland and Hamilton and features the diverse landscapes of the Great Ocean Road, the Grampians, the volcanic plains and the Budj Bim National Heritage Landscape, which is sacred to the Gunditjmara people.

The Warrnambool City, Corangamite Shire, Glenelg Shire, Moyne Shire and Southern Grampians Shire Councils are all within our service area.

The region’s agriculture (particularly dairying), forestry, education, manufacturing, tourism and healthcare contribute more than $5 billion in gross regional product to the Victorian economy each year.
