Summarise this article
What are oysters?
Oysters are saltwater molluscs known as “bivalves” – meaning they have two hinged shells. As filter feeders, they play a vital role in maintaining healthy waterways. In New South Wales, oysters usually grow in marine and brackish waters, often clinging together to hard rocky surfaces. Other species are found in different habitats. The Pinctada maxima, for example, likes warm, tropical waters off the southern hemisphere – particularly around northern Australia, Indonesia and French Polynesia. Our Pinctada maxima oysters are cultivated in the remote waters of our Cygnet Bay Pearl Farm, located on the Dampier Peninsula, Western Australia.
People are often surprised to learn that oysters are living animals with quirky habits. If you hold one, it might move, open its shell, or even squirt water at you! Children love experiencing this on our farm tours.
While oysters are now a beloved staple of Sydney’s seafood scene, their salty, ocean-like flavours have long been part of Indigenous food knowledge. In particular, Angasi oysters are considered a local delicacy by the local Darkinjung people.
Oysters play a vital role in marine ecosystems. According to the WWF they remove algae and excess nutrients from the water, greatly improving water clarity and quality. Oyster reefs also provide shelter and food for a variety of marine life, acting as nurseries for fish and supporting biodiversity and marine conservation.
But oysters aren’t just good for the ocean, they’re good for you too!
How are oysters good for you?
Oysters are rich in zinc, omega-3 fatty acids, vitamin B12, and other essential nutrients. Further to that, they support immune health, heart health, and even cognitive function. What can’t these little creatures do?
Why oysters thrive in the Lower Hawkesbury
The lower Hawkesbury’s unique natural features such as the exact salinity, protected coves and inlets and nutrient-rich currents, combined with a ream of official government protections in terms of pollution and overfishing for example, has created ideal conditions for several oyster species to thrive.
The oyster heartlands
Sometimes known as the Sydney Rock oyster heartlands, the Lower Hawkesbury River is a place where freshwater from the Blue Mountains meets the Pacific Ocean, creating an ideal oyster habitat. This perfect balance of fresh and salt water, combined with nutrient-dense flows, gives our local oysters their distinctive, complex flavour.
The river’s winding channels are protected from the ocean’s waves, reducing stress on the oysters and making them easier to farm. The tidal waters bring steady supplies of phytoplankton meaning the oysters grow plumper and quicker, and the river’s abundance of native oysters mean that the waters are clean and clear.
Regulations governing oyster production
The Lower Hawkesbury is one of Australia’s most regulated waterways. The water quality is monitored fortnightly by the NSW Food Authority, and oyster farms are closed for harvesting if safety standards are breached.
The Lower Hawkesbury’s oyster leases are subject to aquaculture zoning which are designated areas set aside for responsible oyster farming. Leaseholders are required to follow strict protocols for harvesting, cleaning and handling to ensure food safety. There are also environmental safeguards, traceability and compliance requirements around collaborative stewardship.
Together the Lower Hawkesbury’s unique marine environment, combined with strict government protections, create one of Australia’s most ideal and carefully managed environments for oyster farming.
Sustainable oyster farming at Broken Bay Pearl Farm
We are proud to be part of the push for sustainable seafood in Australia. Our regenerative aquaculture practices work in harmony with the natural rhythms of the Lower Hawkesbury River and we are committed to protecting and preserving this unique environment through every stage of our oyster farming process.
Caring for young oysters
Oyster farming is labour intensive work!
Born around a full moon, oysters start out life as free-swimming larvae before growing into “spat”, tiny oysters with their shells already forming. Spat live in hatchery tanks where the water variables are controlled, and they feed on a diet of algae without the threat of predators.
Once transferred to the Lower Hawkesbury, our juvenile oysters live in fine mesh baskets suspended in the water. This setup protects them from predators while allowing them to feed naturally by filtering algae from the water. We do not feed our oysters or use any chemicals in our aquaculture. We rely entirely on clean, nutrient-rich water, meaning that environmental stewardship is essential to our success.
As the oysters grow, they are graded by size and moved into net baskets which float and roll with the tide. Depending on the species, these baskets may be flipped to maintain shell shape and reduce fouling. Other oyster species must be hand-cleaned each month to remove barnacles and other organisms that could otherwise harm or kill the oyster.
Harvesting mature oysters
Oysters take between 12 and 36 months to reach harvest size, depending on their species and the environmental conditions in each season. Events such as heavy rainfall can be fatal for oysters. To mitigate this risk, our farming team closely monitors the weather and salinity, moving our oysters to leases that are less likely to be negatively affected. Once they reach maturity, our oysters are carefully selected and harvested by our expert team.
Many of our oysters are served fresh during our Oyster Tasting experiences at the farm, while others make their way to top restaurants and boutique seafood outlets. This slow-growing, low-impact process produces oysters with exceptional flavour and texture, playing a vital role in protecting the precious marine ecosystems where they grow.
What oyster species are grown at Broken Bay Pearl Farm?
Here at Broken Bay Pearl Farm, we have been proudly cultivating premium Australian oysters for both consumption and pearl production since 2003. From our Lower Hawkesbury River home, we sustainably farm three oyster species, each with their own unique characteristics and contribution to our ecosystem and industry:
- The Sydney Rock oyster (Saccostrea glomerata),
- The Akoya pearl oyster (Pinctada fucata), and
- The Angasi oyster (Ostrea angasi).
In edible oysters, the part we enjoy is the adductor muscle, often referred to as pearl meat.
Sydney Rock oysters
The region’s most famous oyster, the Sydney Rock oyster is native to the east coast of Australia, and usually thrives in sheltered estuaries and coastal bays. It’s a resilient little species that likes the intertidal space, living part time above the water and part time below, especially where mangroves grow.
Sydney Rock oysters take around three years to mature. This is relatively slow by oyster standards but contributes to its impressive size and a rich, buttery flavour that has won over food-lovers worldwide.
Angasi oysters (native flat oysters)
Less famous than the Sydney Rock oyster, the Angasi oyster’s (Ostrea angasi) star is on the rise. Said to be the “oyster lover’s oyster” Angasis are a large, flat oyster with a rich, mineral flavour and voluptuous flesh. They like to live in subtidal areas below the water and taste incredible in winter.
This Indigenous delicacy was once prolific along Australia’s east coast, but overfishing pushed them to the brink of extinction. It took a concerted effort by NSW’s oyster farming community to bring them back. Their hard work has paid off, with Angasis becoming increasingly sought-after by high-end restaurants and savvy consumers.
We began cultivating Angasis in 2024, and they have featured on our Oyster Tasting experiences since December.
What do Angasi oysters taste like?
Angasi oysters have a bold, mineral flavour and a luxurious, silky texture. They’re flat and wide, resembling European flat oysters. Their taste is earthier than Syndey Rock oysters, perfect for those who love a stronger, more savoury flavour profile.
Akoya oysters
And last but definitely not least, here at Broken Bay Pearl Farm we are proud to be the only farm in Australia growing Akoya oysters (Pinctada fucata) for both pearl and seafood production.
Akoyas are wonderful creatures with a unique, vibrant shell that gives the Akoya pearls their incredible lustre and hues. Dainty in size when compared to Angasis or Sydney Rocks, these little oysters live underwater and will only move up to one foot in their whole lives.
At around two years old, the largest Akoyas will be put aside for pearl seeding, whilst the rest will be harvested for consumption. We are so proud of our sustainable farming practices where no oyster is wasted.
What does the Akoya oyster taste like?
The flavour profile of an Akoya oyster is incredibly unique! Native to the Broken Bay area, Akoyas thrive alongside seagrass beds. This nutrient dense environment contributes to their distinctive flavour and texture, which is described as a combination of abalone, scallop and oyster. They taste amazing raw, but also smoked, cured or cooked. Its flavour and versatility make them a highly prized seafood delicacy.
How to eat Akoya oysters?
The flavour of the Akoya oyster is delicate with a hint of sweetness. Adding flavours like lemon, garlic, ginger adds a wonderful complexity and creates a depth to the overall eating experience.

Sydney Rock vs Angasi vs Akoya oysters: Which is the best?
So, which of these oysters are the best? It really depends on your taste. Sydney Rock oysters are smaller, with a creamier taste. Angasis taste clean and earthy with a mineral after taste. Akoyas are bold, yet slightly sweet.
You can enjoy our three oyster species on our popular Oyster Tasting experiences.
Cygnet Bay Pearl Farm and the Australian South Sea pearl oyster
There is one other species worth mentioning, and it is grown at our sister pearl farm located at Cygnet Bay on the Dampier Peninsula in Western Australia. Pinctada maxima, the legendary species behind large, lustrous pure white Australian South Sea pearls, has gaining recognition in fine dining circles, with its fresh pearl meat commanding prices of up to $200 per kilo.
Aboriginal communities on the Dampier Peninsula have been eating the ear-shaped adductor muscle for centuries. More recently, it was favoured by Japanese, Malay and Filipino divers who descended on Broome during the mid-1800s “pearl rush”.
Today, pearl meat features on menus at high-end restaurants like Sydney’s Bentley Bar and Restaurant. “Chefs are waking up to the possibilities that pearl meat presents,” says James Brown, third generation pearl farmer and managing director of Pearls of Australia in this article.
“It’s an unusual product, unique in flavour profile and texture, and there’s also long-standing intrigue and romanticism that comes with the pearling industry. But most of all, this is a rare ingredient. If a restaurant wanted to use it, they’d be very lucky to be able to get hold of it. People like that. It creates demand.”
The sale of Pinctada maxima pearl meat is one example of our zero-waste approach, part of our wider commitment to sustainable aquaculture.
