Diana Olive Oil

Diana Olive Oil is a multi-award-winning third-generation family business located in the Fleurieu Peninsula, 45 km south of Adelaide near the iconic McLaren Vale wine region. They produce award-winning premium extra virgin olive oils at both the national and state levels and have been certified for exceptional quality and performance.

Established in 1987 with traditional basket pressing, the operation has evolved to utilise modern centrifuge technology, crafting premium oils from estate-grown olives nurtured in Willunga's Mediterranean-like climate. Today they serve as a central hub for olive growers, offering comprehensive services including bulk olive oil sales, contract milling with a 500kg minimum delivery (servicing South Australian growers for over 35 years), packaging for brands of all sizes, and in-grove consulting to help convert underperforming land into productive olive groves.

Their product range includes Red Label Extra Virgin Olive Oil, Novello, Chef's Blend, and Whole Kalamata Olives, available directly and through stockists including de Rose Kitchen in Willunga. They now supply over 100 Australian and international businesses and manage the Waikerie Grove project in South Australia's Riverland region.
