Colac

Colac is a rural farming town in southwestern Victoria, Australia, on the southern shore of Lake Colac southwest of Melbourne. The name traces to the Gulidjan Aboriginal word Kolak, describing the freshwater lake and sandy soils of the surrounding landscape. Extensive volcanic plains formed by prehistoric basalt lava flows characterize the surrounding grazing country.

Gulidjan people inhabited the volcanic plains and lake margins for generations before European pastoralists arrived. Hugh Murray established the first permanent sheep station in the district in 1837, selecting fertile grasslands along the southern lake basin. Brick stores, blacksmith workshops, and inns developed around the Murray homestead during the 1840s. The Victorian Railways opened a direct rail line from Geelong in 1877, turning the settlement into a primary forwarding depot for wool clips and dairy produce. Rural subdivision and swamp drainage throughout the early 20th century expanded family dairy farming across the fertile basalt flats.

Bulla Dairy Foods operates major dairy manufacturing plants in the settlement, producing family ice cream tubs, thickened table cream, and cottage cheese from fresh milk supplied by surrounding farms. Australian Lamb Company processes grass-fed lamb and mutton for wholesale meat distributors, while AKD Softwoods mills sustainable plantation pine into structural house framing, treated fence posts, and paper chips. Fertile basalt soils across the surrounding plains produce heavy clips of fine Merino wool, grass-fed beef cattle, and harvested winter grain crops.

Lake Colac borders the northern edge of the town as an expansive natural freshwater lake used for recreational sailing and competitive rowing regattas. Colac Botanic Gardens features mature cypress avenues, formal flowerbeds, and lakeside lawns designed in the late 19th century by landscape botanist William Guilfoyle. Red Rock Volcanic Complex rises north of town with steep cinder cones and crater lookouts overlooking the Corangamite basin. Great Otway National Park preserves dense temperate rainforests and giant mountain ash eucalyptus trees along the southern forested ranges.
