East 33 Limited, an entity originally established in 2019 and headquartered in Tuncurry, Australia, historically engaged in the cultivation, processing, and distribution of Sydney Rock oysters within the Australian market. Its operations were structured across integrated segments encompassing oyster farming, robust distribution networks, and complementary retail and hospitality ventures. The company was deeply involved in the growth and wholesale supply of live oysters, alongside their wholesale and direct-to-consumer retail channels, which included online sales and associated gourmet products. Notably, it also operated restaurant services and offered liquor sales to its customer base. East 33 sought to highlight the unique quality and rare provenance of Sydney Rock Oysters, which thrive exclusively along the East Coast of Australia. The company was delisted from the Australian Securities Exchange in 2024 following its acquisition by Yumbah Aquaculture Ltd, with the transaction finalizing in October 2024.
