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 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.
