This review contains a summary of the nutritional analysis and potential health benefits of eight seaweed genera, to support decisions on genera/species that could be cultivated in South East Australia, and integrated into aquaculture production systems. The health benefits associated with seaweeds are critical in identifying marketable products for a future seaweed industry. By identifying the potential for seaweeds to be marketed as a healthy food, a strategy with which to progress the development of pilot commercial systems of seaweed culture of local species, and integrate these systems with the current developments in the aquaculture industry can be made. Australia may be just a few years away from becoming truly competitive in the seafood aquaculture industry, if it rises to the challenge of promoting itself as the healthy and environmentally friendly primary producer. Seaweed culture can be a key factor in this challenge.
