Omega Walnuts is a family-run team of Western Australian walnut farmers. They have been growing their walnuts in the rich horticultural areas of Manjimup and Nannup since the beginning of the century.
The farm consists of two orchards with some 64 HA planted with varieties including Chandler Howard and Tullare. They are Australia’s largest certified organic grower of walnuts. The walnuts are carefully processed on-site in Manjimup using Omega’s uniquely designed process to preserve the delicate omega oils.
Sales are currently online only, as they do not offer sales directly from the farm. You can buy fresh walnuts in-shell or shelled, as well as extra virgin walnut oil, through their website or from select stockists.
