The traditional custodians of the land surrounding the Tweed River are the Aboriginal people of the Minyungbul, Tulgi-gin, Cudgenburra, and Mooburra dialects,.

D. [Cook's Point Danger - Fingal Head] On the South Side of this headland we had the satisfaction to discover a considerable river with an apparent clear entrance.

Observed the River from the Mast head take a SW direction running through a moderately elevated country towards the Base of Mt.

[10][11] Monday 27 October 1823: The wind being fair, we immediately got under way, and continued our course to the northward till Friday afternoon, when it shifted, and came on to blow so hard, that we determined to run in shore and look out for anchorage; this we found under the lee of a small island off Point Danger (so named by Captain Cook), about a mile from the land.

While running down for this place, we perceived the mouth of a large river about a mile and a half to the northward; and next morning at daylight the master was dispatched in the whale-boat to ascertain the possibility of taking the vessel into it.

The rocks which formed the base was evidently of volcanic origin: it was of dark colour, full of small holes and extremely hard, while on the western side many regular circular cavities, some of which were about four or five yards in diameter at top, and tapered down gradually towards the bottom, which was usually filled with round stones.

One of these holes, in particular, had a communication underneath with the sea, and at every returning surf threw up considerable quantities of water with a loud noise.

Lieut Oxley has since (1823) discovered this to be the case, for he found a stream empting itself into the sea, by a bar harbour close to Point Danger.

The order failed to stop the channel from shoaling and instead necessitated regular dredging and completely inhibited the longshore transport of sand northwards.

[18] In 2001, an artificial sand bypass system was implemented, in part based on the successful operation of the Gold Coast Seaway.

The term probably originates from southern Australians' summer vacation trips driving along the Pacific Highway through the scenic New South Wales North Coast.

The highway crosses many rivers along its route, with the Tweed being the last one before reaching the holiday destinations of the Gold Coast, just on the other side of the Queensland border.

[17] During Cyclone Oswald, the Tweed River was subject to major[20] flooding, brought about due to the storm's residual effects and associated monsoon trough that passed over parts of Queensland and New South Wales.

[21] In late March 2017 rainfall from Ex-Tropical Cyclone Debbie caused major flooding in the Tweed Valley, the Murwillumbah gauge recording a peak of 6.2 metres.
