Reefs and comprise Inner Reef, South Reef and Outer Reef. There has been controversy over the naming of Point Danger for many years. It seems the controversy began as early as 1823, when government surveyor, John Oxley, set out in HMCS Mermaid to explore Port Curtis, the site of Gladstone. Oxley explored Moreton Bay, which had been named by Captain Cook, and the Brisbane River, as well as exploring and naming the Tweed River. It was during this voyage that Oxley encountered what is now known as Fingal Head and reported it as being Point Danger, so named by Captain James Cook. Oxley's favourable report on the Brisbane River saw him return the following year and establish the colony of Brisbane under the direction of Sir Thomas Brisbane, Governor of New South Wales in 1824. At some time in 1828 Henry John Rous, travelling north, charted the Tweed River, which he named the Clarence River, unaware that it had already been named the Tweed River by Oxley in 1823. Rous came up the eastern coastline and around the reef off the coast of the feature now known Fingal Head, and arrived at a place now called Rainbow Bay, so named after his ship. It was there that Henry Rous has arguably caused all of the confusion. He named the, at the time, unnamed site of Point Danger as being that of Cook's Point Danger. There was further confusion as to the location of Cook's Point Danger when in 1840 surveyor Robert Dixon was given the task of doing the first land survey of the area. Dixon's role was to map the New South Wales and Queensland border. He was told to map the border from the west to Point Danger on the east coast. Dixon took the location of Cook's Point Danger as being that of the one identified by Rous in 1828 rather than the one identified by Oxley in 1823. In 1970, on the 200th anniversary of Cook's naming of Point Danger and given that the location seemed to be correct, a memorial was placed at the current site and the New South Wales, Queensland and Federal governments combined to erect the Point Danger Captain Cook Memorial Lighthouse. However, in 1971, the following year, after much debate about the location of Cook's Point Danger and the Queensland-New South Wales border, the Geographical Names Board declared: little doubt exists
