Sydney Rock Oysters

The Sydney Rock Oyster (*Saccostrea glomerata*) is native to Australia, where it’s found in small numbers. They are cultivated in estuaries and bays from southern Queensland to the southern border of New South Wales, grown under estuary-specific Environmental Management Systems. Sydney Rock oysters are also found in small numbers in Tasmania and southern New South Wales. They are grown in bays, inlets, and sheltered estuaries from eastern Victoria, along the east coast of New South Wales, and north to Hervey Bay, Queensland. A small population also exists in Albany on the southwest coast of Western Australia, where they are farmed.

Angasi/Australian Flat Oysters

Angasi oysters, also known as Australian flat oysters, are native to Australia and have been consumed by Indigenous Australians for centuries. They are typically found in the shallow waters of estuaries and coastal bay substrates, predominantly in Tasmania and southern New South Wales. They are known for their unique, savoury, and complex flavour, offering a glimpse into Australia's historical culinary traditions.

Angasi oysters are large, rounded oysters with a cup-shaped lower valve and a flat or slightly concave upper valve. They occur naturally along the entire coast of New South Wales and extend into southern Queensland, as well as into all the southern states and Western Australia. They were once plentiful around southern Australian shores, from New South Wales to Fremantle, including Tasmania. However, due to historical over-harvesting, they became nearly extinct in the late 19th century, and their populations have not fully recovered.

The Angasi oyster is now very rare and is making a slow comeback. They are prized for their rich depth of flavour, full-body texture, and subtle flintiness, which lends itself well to cooking. Their flavour is often described as savoury and rich, with a mildly gamey taste and a slightly fishy aftertaste. Angasi oysters are considered a delicacy by informed consumers and are highly regarded for their unique flavour profile.

In the 21st century, commercial oyster growers in southern Australia have started experimentally farming Angasi oysters as a way to diversify their businesses. The Estuary Care Foundation, a non-profit organisation in South Australia, has been conducting trials to grow Angasi oysters in the Port River and adjacent waters. Larger-scale projects, such as the Rigid Oyster Basket project, have also been undertaken to promote the reestablishment of Angasi oysters in Port Adelaide Inner Harbour and Gulf St Vincent.

Pacific Oysters

In 2010-2011, an outbreak of Pacific Oyster Mortality Syndrome (POMS) impacted populations of wild Pacific Oysters in Port Jackson/Sydney Harbour and wild and farmed triploid Pacific Oysters in Georges River/Botany Bay. Since then, POMS has been detected in other areas of New South Wales, including the Hawkesbury River.

Despite the risks posed by POMS, Pacific Oysters remain a popular delicacy in Australia, particularly in Franklin Harbour, where they are celebrated by the Pacific Oyster Co. with events like Easter celebrations featuring "Ollie the Oyster".

Coffin Bay King Oysters

Oysters in Australia include the Sydney Rock Oyster, the Pacific Oyster, and the Angasi Oyster. The Sydney Rock Oyster is native to the east coast of Australia, cultivated in estuaries and bays from southern Queensland to the southern border of New South Wales. The Pacific Oyster, on the other hand, was introduced to Australia from Japan, first appearing in south-eastern and western Australian waters in the 1940s.

One notable variety of Pacific Oyster is the Coffin Bay King Oyster, which is renowned for its impressive size and pristine waters. The Sellen family has been farming the pristine waters of Little Douglas at Coffin Bay in South Australia for two generations, supplying Australia's favourite oysters across the country. Unlike most oysters, which are typically grown for about 18 months, Coffin Bay King Oysters are allowed to grow for up to 6 or 7 years.

Coffin Bay is located on the Eyre Peninsula in South Australia and is known for its pristine waters and abundant seafood, including the famous Coffin Bay King Oysters. The region's cool, clean waters and sheltered bays provide the perfect environment for oyster farming.

The Coffin Bay King Oysters are known for their distinctive flavour and texture, which is influenced by the unique combination of cold, clean Southern Ocean waters and the calm, protected waters of Coffin Bay. The oysters have a briny taste with a hint of sweetness and a creamy texture, making them a favourite among oyster connoisseurs.

In addition to their size and flavour, Coffin Bay King Oysters are also prized for their sustainability practices. The Sellen family and other oyster farmers in the region prioritize responsible and sustainable farming methods, ensuring the long-term viability of the oyster industry in Coffin Bay.

Tasmanian Oysters

Tasmania's oyster farming industry is a significant business, employing over 300 locals who cultivate, harvest, and distribute oysters all year round. The industry generates more than $24 million AUD annually. Tasmania's oysters are mostly found along the north, east, and southeast coastlines of the island, with the Bay of Fires, Freycinet Peninsula, and Wineglass Bay being notable locations.

The Tasmanian Oyster Co. farms over 220 hectares of pristine Tasmanian waters on the North West Coast. They are committed to using better technology to produce higher-quality oysters.

Tasmania's oysters are predominantly of the Pacific oyster variety, which was introduced to Tasmania in 1947. Pacific oysters are native to Japan and were first brought to Australia in the 1940s for aquaculture. They have a thin shell with no hinge teeth inside the upper shell and are distinguished by their purple or brown adductor muscle. They can be found on hard substrates in intertidal and shallow subtidal zones, typically to a depth of about 3 metres.
