a description of the ports, islands and coast between Port Jackson and Breakesea Spit, the following description of the Tweed River confirms that Captain King clearly considered Point Danger to be the southernmost of the two points: The Tweed is a river communicating with the sea by a bar, on which there is twelve feet of water, it is situated about a mile and a half to the north of a small island off Point Danger, which lies in latitude 28° 8' Captain Henry Rous further examined the Tweed River in 1828, and incorrectly identified the present-day Point Danger, as the Point Danger of James Cook and recorded the name 'Cook's Island' rather than 'Turtle Island' of Oxley [Rous named Oxley's Tweed the Clarance River]: The River Clarance, or more properly the Tweed, discovered by Mr. Oxley, but not explored, is in lat. 28° 9', long. 153° 34' bearing N.W.½ W. from Turtle Island distant 2 ½ miles – it is situated to the southward of a Bluff Head, connected with the Main by a flat sandy Isthmus, 250 yards wide from high water mark forming a boundary to the river on one side, and to capacious bay to the northward – affording good anchorage and shelter from East Southerly to North….There is a small river about 10 miles NW by W from the *north bluff of Point Danger inaccessible for boats. The Tweed was named after the River Tweed in Scotland. Mouth stabilization The first training walls were built in 1891. Between 1898 and 1904 training walls were constructed from Chinderah to the entrance. In 1962, these walls were extended in order to maintain a deep channel. The order failed to stop the channel from shoaling and instead necessitated regular dredging and completely inhibited the longshore transport of sand northwards. The southern Gold Coast beaches were soon faced with intense erosion during storms which was not replenished. By 1998 the river entrance was dredged clear of sand for navigable purposes. Three million cubic metres of sand had been removed from the river mouth. In 2001, an artificial sand bypass system was implemented, in part based on the successful operation of the Gold Coast Seaway. The level of sand on southern Gold Coast beaches soon returned to pre-1960s levels. Colloquial use Even though parts of the river are a few kilometres within the New South Wales side of the border,
