In enviable weather, on the southeast coast of Australia, a punt glides over Merimbula Lake towards an oyster lease, with a passionate young oyster farmer Dom at the helm. Its a romantic picture of tranquil beauty and a life close to nature, attuned to the rhythm of the tides. But Dom and fellow locals swear the waters getting warmer and the storms more severe. The only oyster its legal for them to grow in the lake is the famous gourmets delight, the Sydney Rock Oyster. Taking three years to mature, its highly vulnerable to pollution and changes in water temperature and salinity. There are diseases too and the threat of competition from a much faster growing non-native species, the Pacific Oyster. OYSTER follows Dom and Pip into their home, their work-shed, out on their punt and into the water, to see what its like to be raising two energetic young boys, while youre working big hours to keep a few million oysters alive, and any decision you make to deal with the pressures of climate change, environmental damage and increasing disease could have far reaching consequences.
