Finniss SA 5255

Set within South Australia's globally significant Fleurieu landscape, this remarkable 55-hectare (136-acre) holding presents a rare opportunity to steward one of the region's most ecologically rich and visually breathtaking properties. With 43 hectares protected under Heritage Land and an additional 12 hectares revegetated, Finniss Retreat is nature at its best.
Rare plant species, abundant birdlife, and thriving native fauna coexist here in harmony. Sustainability is not a concept, but a lived reality-where landscape, biodiversity, and purpose unite. From golden pastures to ancient bushland and panoramic views across untouched land, Finniss Retreat is not just a home. It is a living legacy.

THE LAND
Spanning approximately 55 hectares, Finniss Retreat is a property of exceptional scale and ecological significance. The land transitions from rolling native grasslands to majestic trees and rare flora, creating a rich mosaic of habitats.
Kangaroos, echidnas, rosellas, cockatoos, wedge-tailed eagles, and other native species roam freely across the landscape. With sweeping views, absolute privacy, and walking tracks through Heritage Land, the property offers peace, seclusion, and a deep connection to nature.
