Beeac is a small rural town, 17 km north of Colac in western Victoria. It is on the eastern shore of Lake Beeac, one of several salt lakes in the Colac district. It is thought that the name was derived from an Aboriginal word meaning salt water, a reference to the lake.
The land east of the lake and around the town is mostly flat plains, and the land to the west is stony rises. Both, however, have soil from lava flows and are good for dairying and grazing. Potatoes and onions were also grown on the fertile plain.
