Nauru's major trading partner is Australia. Other important partners are New Zealand, Japan, South Korea, and Indonesia. These countries purchase Nauruan phosphate for use as a fertilizer. Phosphate is Nauru's only export. Apart from some locally-produced foods (fruit, coconuts, chickens, and pigs), virtually everything is imported into Nauru, including most foods, fresh water, fuels, motor vehicles, building materials, and machinery. Most of these goods are imported from Australia.
