For years, the old saying that you should only eat oysters in months with an “R” has shaped how people think about oyster seasonality. But is there any truth to it? Thanks to modern aquaculture, expert oyster grading and the natural diversity of Australia’s estuaries, high-quality oysters are available year-round in Australia. Let’s break the myth and explore how Australia’s Oyster Coast ensures you can enjoy premium oysters in every season.
Yes, You Can Eat Australian Oysters Year-Round
The old adage about only eating oysters in months with the letter "R" is a myth. You can find oysters available and safe to eat throughout the year.
Peak Season
Oyster quality peaks at different times of the year, depending on the species, region, season, and estuary type. For Sydney Rock oysters, a native Australian species, peak condition shifts from spring to winter as you move south along the coast.
In general, northern Sydney Rock oysters are at their best in spring.
Mid-coast oysters reach peak quality from summer through autumn.
Southern oysters are at their finest in late autumn through winter.
That said, oysters can be found in excellent condition outside their traditional peak seasons, influenced by environmental factors such as weather and water temperature. The seasonality of Sydney Rock oysters, Pacific oysters, and Angasi oysters is shaped not just by the air temperature but also by the temperature of the water they grow in.
Oyster Quality
Oyster quality is influenced by factors such as water temperature, regional seasonality and farming practices. At Australia’s Oyster Coast, we harness regional seasonality, innovative technology and careful management to maintain consistently high-quality oysters year-round.
Taste Preferences
Some people find oysters more flavourful in the winter months, appreciating their richer taste and lower salinity. Our oyster brands, Appellation Oysters and Oystersmiths, use estuary tasting notes and detailed flavour profiles to showcase the unique taste variations and seasonality of different oyster-growing regions.
Food Safety
Oyster farms and authorities regularly test water quality and implement measures to ensure the safety of oysters for consumption, regardless of the time of year.
Examples of Oyster Varieties & Their Seasons
While Sydney Rock oysters are the most common variety in NSW, other Australian oysters, such as Pacific oysters from Tasmania and South Australia, are also available.
Sydney Rock Oysters: Available year-round, with peak quality varying by estuary. Generally, the north coast of NSW produces the best Rock oysters in summer, while the south coast reaches peak condition in winter.

Mud oyster are best from May to August and better avoided from November to March.

Understanding the Natural Oyster Cycle
Oysters are deeply connected to their environment, with their growth and quality influenced by water temperature, salinity, and local estuarine conditions. Sydney Rock oysters, for example, follow a seasonal cycle where their peak condition moves from north to south along the New South Wales coast:
Northern estuaries (e.g., Port Macquarie, Nambucca, Wooli Wooli) – Best in spring and early summer.
Mid-coast estuaries (e.g., Port Stephens, Wallis Lake, Shoalhaven) – Peak season extends through summer and autumn.
Southern estuaries (e.g., Clyde River, Merimbula, Wonboyn) – Reach peak quality in late autumn and winter.
This natural variation means top-quality oysters are always available, if you know where to look. At Australia’s Oyster Coast, we operate across seven farms spanning the north and south coasts of NSW and source from independent farmers nationwide. This ensures a consistent, year-round supply, aligned with seasonal peaks for the best possible quality.
Expert Grading & Australia’s Oyster Coast Sourcing Program
At Australia’s Oyster Coast, expert oyster graders work year-round to ensure only the best oysters reach consumers. Grading accounts for size, shape, meat condition and taste, so that regardless of the time of year, you’re getting an oyster at its prime.
Additionally, Australia’s Oyster Coast’s sourcing program allows access to premium oysters year-round by selecting the best oysters according to their peak seasons. By tapping into different estuaries along the NSW coastline, we provide restaurants, seafood lovers and chefs with consistently high-quality oysters, regardless of the time of year.
