South Australia Implements World-First Ban on Fish-Shaped Soy Sauce Containers

Overview of the Ban
South Australia has become the first region globally to ban fish-shaped plastic soy sauce containers, effective September 1, 2025. This initiative is part of a broader effort to reduce single-use plastic waste and protect marine life. The ban specifically targets pre-filled containers of 30 milliliters or less that come with a lid, cap, or stopper, commonly found in takeaway sushi meals. Larger soy sauce bottles and sachets will remain unaffected.
Legislative Context
The ban builds on previous environmental legislation enacted in September 2023, which prohibited various single-use plastic items, including supermarket carrier bags, plastic straws, cutlery, drinks stirrers, and cotton buds. The South Australian government aims to mitigate pollution, cut carbon emissions, and safeguard marine ecosystems. Environment Minister Susan Close emphasized that these small containers, while used for mere seconds, can persist in the environment for decades, contributing to microplastic pollution.
Historical Background
The iconic fish-shaped soy sauce containers, known as shoyu-tai in Japanese, were invented by Teruo Watanabe in 1954. Initially made from glass or ceramics, they transitioned to plastic due to cost-effective mass production. Despite being made from recyclable polyethylene, their small size renders them difficult to process in recycling facilities, leading to a high likelihood of ending up in landfills or as litter.
Environmental Impact
Experts have raised concerns about the environmental implications of these containers. Dr. Nina Wootton, a marine ecologist at the University of Adelaide, noted that marine life often mistakes these plastic items for food, posing a significant threat to ecosystems. The South Australian government has stated that without intervention, the annual flow of plastic into the ocean could triple by 2040, reaching 29 million tonnes.
Criticism and Opposition
While environmental groups have welcomed the ban as a positive step, they argue that more comprehensive measures are necessary. Cip Hamilton, a campaign manager at the Australian Marine Conservation Society, called for stronger laws to reduce plastic production and hold businesses accountable for their waste. He emphasized the need for systemic change to effectively address plastic pollution.
Official Statements
The South Australian government has framed the ban as a crucial move towards reducing plastic waste. Susan Close stated, “Each fish-shaped container is used for just seconds yet remains in the environment for years, causing harm and contributing to microplastic pollution.” Premier Peter Malinauskas echoed this sentiment, highlighting the importance of minimizing single-use plastics for environmental benefits.
What's Next
As South Australia enforces this ban, other Australian states, such as New South Wales and Tasmania, are considering similar measures. The ongoing legislative efforts reflect a growing recognition of the need to combat plastic pollution and its detrimental effects on the environment.

- “Each fish-shaped container is used for just seconds, yet remains in the environment for decades or centuries if littered,” — Susan Close, Environment Minister, South Australia
- “What our oceans really need is for state and federal governments to introduce strong laws that reduce plastic production and consumption and hold businesses accountable for the products they place on shelves, otherwise Australia’s marine life and coastlines will continue to suffer under mountains of plastic pollution” — Cip Hamilton, Campaign Manager, Australian Marine Conservation Society
- “The small size of the fish-shaped soy containers means they’re easily dropped, blown away, or washed into drains, making them a frequent component of beach and street litter,” — Susan Close, Environment Minister, South Australia
