The bag limit applies for cast seaweed for private use only. Collection is only from beaches with public access. Seaweed attached to the sea floor must not be harvested.


Found at and below the low-tide level around exposed areas of the west, east and south coasts of Tasmania. Can occur up to three metres above the low tide mark and prefers areas of high wave surge. When alive, seaweeds are an important part of the marine ecosystem and cannot be cut or harvested in Tasmania. Cast seaweed is also an important micro habitat for small beach invertebrates.
