South Australia has become the first region in the world to ban fish-shaped plastic soy sauce dispensers—known as shoyu-tai—alongside other single-use plastics, effective 1 September 2025. Under the new law, any pre-filled soy sauce container under 30 ml without a cap or lid (including those fish shapes) is now illegal. The state government is encouraging sushi shops and take-aways to move toward bulk or reusable dispensers instead.
Officials point out that these novelty fish packets, while iconic, pose outsized environmental risks. Their small size makes them easy to drop, blow away, or wash into drains, allowing them to become litter or marine pollution. Moreover, recycling systems often can’t capture such tiny rigid plastics. With this ban, South Australia joins a growing number of governments taking action against problematic plastics at their source.
