Hi Pingtzir and Sunil,
While bush tucker refers to any food native to Australia, including plants and animals, we’ve defined bush tucker as food from native plants in the project opportunities (4.1 and 4.2) under the Caring for the Land design area. Generally, native plants can be found in different habitats, including the coastal area.
In this case, food sources (oysters, fish, abalone, etc.) from the marine environment will likely fall under the Caring for the Sea design area.
