 Before colonisation, Mamu people moved seasonally within their traditional country, accessing and using important food sources including seafoods, freshwater fish, game animals, rainforest fruits and roots.Certain plant species used by rainforest Aboriginal tribes in this area on a regular basis are highly toxic, and careful preparation using time honoured methods were employed to make these food sources safe for eating.During particular seasons, these toxic foods would form a staple of the tribes' diets.
