The Oil Discovery That Changed Outback Australia: The Cooper Basin

Hidden beneath the deserts of South Australia and Queensland lies the Cooper Basin, Australia's most successful onshore petroleum province. Since the discovery of oil and gas in the 1960s, the basin has produced more than 250 million barrels of oil and helped power Australian homes, industries, and cities for decades. What began with the Gidgealpa gas discovery in 1963 and the Tirrawarra oil discovery in 1970 evolved into one of the largest exploration successes in Australian history. Thousands of wells have been drilled, hundreds of oil and gas accumulations have been discovered, and billions of dollars have been invested in infrastructure across one of the most remote regions on Earth. Yet despite its enormous contribution to Australia's energy security, the Cooper Basin remains largely unknown to the public. Its story is one of ancient swamps, buried hydrocarbons, geological timing, technological innovation, and a petroleum province that continues to evolve more than sixty years after its first major discovery.
