Grampians Olive Co. is one of Australia's oldest olive groves, established in 1943. The 100% family-owned business, historically known as 'Toscana Olive Plantation', changed its name in 2015 to reflect its Grampians location. It is renowned for producing some of the best organic olive oil in Australia, using dryland organic farming methods. Their Certified Organic oils are cold pressed, unrefined, and unfiltered, with the entire production process managed from tree to bottle.

Visitors are welcome at the farm every weekday from 11 am to 4 pm, though it is closed on weekends, public holidays, and catastrophic fire days. The business offers an online shop with free shipping for most orders over $100.
