Subsea Estate - WA's Pioneering Open Ocean Winery

In Augusta's pristine waters, where two oceans meet, WA’s pioneering Open Ocean winery Subsea Estate crafts limited edition wines 20 metres beneath the surface.

The Southern Hemisphere's first open-ocean winery, Subsea Estate, brings a fresh perspective to Margaret River wine. Nestled within the stunning Flinders Bay, the natural rhythms of the Southern Ocean transform premium fruit into something extraordinary, crafting our limited-edition wines 20 metres below the surface.

Born from a vision to merge traditional winemaking with maritime innovation, Subsea Estate began its journey in May 2024 with its inaugural deep-sea 'winter' immersion. This pioneering process harnesses the raw power of WA's ocean environment in ways previously unseen in Australian wine. Specialist divers deploy custom-designed vats to precise depths, where constant temperatures and ocean swells influence each vintage.

Continuous motion and oceanic pressure create wines that embody the essence of both land and sea, offering something truly unique for those seeking an adventure in wine.

At the Augusta Boat Harbour marina, guests can explore these ocean-influenced wines through immersive tastings. The cellar door experience features stunning views across Flinders Bay, accompanied by fresh abalone and insights into this dynamic winemaking approach.
