The story of opal in Australia is the story of Tully Wollaston, part poet, part explorer, part entrepreneur. When Tully heard of Australia's first opal find in inland Queensland he headed north by camel, almost perishing in the drought-stricken desert. He survived to see the opal and realize that its quality was so good a world market could be developed for it. This is the story of how he single-handedly pursued that idea, tirelessly visiting Europe and the U.S. to promote the cause and assisting in the major opal strikes being made in Australia - at Lightning Ridge, White Cliffs and, finally, Coober Pedy. By the time of his death in 1931, Australia was the opal capital of the world.
