Ellis' discovery of phosphate excited
John T. Arundel of the Pacific Islands Company and the company decided to pursue rights and access to Nauru's lucrative resource. The negotiations to pursue rights to the phosphate involved four parties: the British and German governments, the newly reorganised Pacific Phosphate Company, and
Jaluit-Gesellschaft (a German chartered company that had been exploiting phosphates on Nauru since the late 19th century). In June 1948, about 1,100
Gilbertese employed on Ocean Island refused to work, with the key demand of the strikers was for higher wages of £10 a month to meet the increased price of goods sold in the trade store. In 1968, Nauru became a sovereign, independent nation. In 1970, the newly formed government purchased the full rights to the phosphate business from Australia for A$21 million. This purchase brought an economic boost to the Republic, as revenues from the mining operations are estimated to have been A$100–120 million annually since independence through virtual resource exhaustion in the early 1990s. Gross production of phosphate from 1968 through exhaustion has been 43 million tons. In 1989, Nauru took legal action against Australia in the
International Court of Justice over Australia's administration of the island, in particular Australia's failure to remedy the environmental damage caused by phosphate mining.
Certain Phosphate Lands: Nauru v. Australia led to an out-of-court settlement to rehabilitate the mined-out areas of Nauru. ==Investments and finances==
