No mention of tribal names.

This is the story of Arnie Duffield, who arrived at Thursday Island, in Torres Strait, the Northern tip of Australia, aged ten, in 1936 - beginning a life-time of adventure. His father worked on the famous sailing luggers, diving boats that harvested pearl shells and pearls for over 100 years up to 1980. Arnie with his father and brother, with their own hands would build their own flotilla of luggers, to operate as a family company over eventful decades: seeing the Great Depression, war and the immediate threat of invasion, a post-war boom in the region, the loss of divers and constant striving for safety at sea, failures of an industry, mounting threats to the environment. For ten years he managed an innovative project cultivating pearls for jewellery, a change from selling shells, the `mother of pearl' used for buttons and ornamentation. The tropical life provided excitement, stimulus, dangers; material for yarns, about crocodiles or sharks, drunks, bad weather at sea, a near-drowning, a mercy dash in a fast boat to save a downed pilot, and a few close shaves on bush air-strips. Arnie became a leading personality in this world, a humourist and practitioner of the wisecrack, always quick with a come-back. From childhood days observing the hectic life of the far-away little port at Thursday Island, Waiben under its traditional name; then working as a young man, repairing warships, and operating the family-owned boats, he became, he would proudly state, a master mariner and proficient ship engineer. He would revel in the island life, enjoying great freedom, getting successes and hard blows; in private life, marrying, starting a family, experiencing the stresses and joys. At 95 he is known as the "last man standing" from days when the fleet would depart under sail.

Sario lives with his family on a remote Torres Strait island, which he never wants to leave – but the winds of change are stirring. The year is 1898 and the pearl-shell trade is at its height. When his father is coerced to join a white trader on his pearling lugger, thirteen-year-old Sario must go to work as a swimming diver to support the family. He can earn more as a pump diver, and is excited by the idea of walking on the sea floor, but the competition is fierce, and the only captain who will take him on runs the worst outfit in the fleet. With the constant danger of shark attack and the storm of the century approaching, can Sario provide for his family and realise his dream?

In an ethnically stratified work force, Japanese, South Sea Islander, Torres Strait Islander and Aboriginal divers brought up from the sea floor the shell that produced mother-of-pearl, and sometimes pearls. Many men died at this dangerous work. This was an industry that could have given the indigenous peoples of Torres Strait an occupation that preserved their identity and independence. Yet in spite of a co-operative lugger scheme that operated fairly successfully in the early twentieth century, a real independence was not achieved. And a resource that could have been conserved by small-scale indigenous harvesting was depleted time and again by the colonial practices of resource-raiding and mass extraction. Regina Ganter charts the progress of pearl-shelling from its heyday through its several crises resulting from overfishing to its present cautious management. The book is greatly enhanced by the oral testimony of divers and boat-owners.
