TheDaintree River is ariver that rises in theDaintree Rainforest nearCape Tribulation inFar North Queensland, Australia. It flows into theCoral Sea.[4] The river is located about 100 kilometres (62 mi) northwest ofCairns in theUNESCOWorld Heritage–listedWet Tropics of Queensland. The area is now primarily atourist attraction.
The river rises on the eastern slopes of theGreat Dividing Range near Black Mountain within theDaintree National Park at an elevation of 1,270 metres (4,170 ft)AHD.[5] The river flows in highly meanderingcourse generally north, then east, then south and then east, through the rainforest where the water is fresh. At this convergence point, an abundance ofwildlife congregate, particularly fish. The river is joined by two minortributaries before flowing through the Cairns Marine Park through thickmangrove swamps where the water is highly saline; and then empties into theCoral Sea, north ofWonga Beach. The mouth of the Daintree River opens onto a giantsandbar that shifts with each changing tide. The river descends 1,270 metres (4,170 ft) over its 127-kilometre (79 mi) course.[3][6]
The catchment area of the river occupies an 2,107 square kilometres (814 sq mi) of which an area of 33 square kilometres (13 sq mi) is composed ofestuarine wetlands.[7]

The river is surrounded by mountains and deep valleys. Combined with the climatic conditions of the area the river is prone to quickly developingfloods with little warning due to the high rainfalls on the 1,000-metre-high (3,300 ft) mountain ranges around the catchment and the influence of the cyclonic forces in the adjacent Coral Sea. In March 1996, record flood levels swamped roads and properties throughout the Daintree region. Statistics gathered at the time recorded 606 millimetres (23.9 in) of rain falling in 24 hours.
In 2011, two new causeways were completed over Cape Tribulation Road, making the drive mostly floodproof in all but the most severe rain events. In particular, the notorious bottleneck at Cooper Creek was raised 3 metres (9.8 ft).
In 2019, the river peaked at 12.6 metres atDaintree breaking the 1901 record of 12.4 metres.[8]
In 2023, a new record of 15 metres was recorded at Daintree after torrential rains from ex-Cyclone Jasper flooded the catchment.[9]
People are drawn to the area for its ancient vegetation, scenic surroundings, and the diverse array of native wildlife and plant species that inhabit the area. Currently, there is no bridge to enable crossing the river, so access is limited to theDaintree River Ferry, a commercial ferry that traverses the river for the purpose of tourism. Other features that surround the river includeKalkajaka,Daintree Range,Thornton Peak and theCape Tribulation Rainforest. The Daintree River is home to a dazzling array oftropical life.
TheKuku Yulanji is the indigenous people who once inhabited the regions surrounded by the Daintree River. The tribespeople werehunter-gatherers who lived in groups of eight to twelve, camping along the banks of the river and living on a staple diet that included a selection of bush tucker harvested from the vegetation from the forest surrounding the Daintree. It has been estimated that the tribe resided on the banks of the Daintree river for over 9,000 years.[10][11]
Due to the ever-shifting deep centre of the sandbar, entering the Daintree River has always been a problem for ship captains. The area was missed byCaptain Cook when passing in the voyage where his ship was wrecked on theGreat Barrier Reef. The Daintree River was first seen byEuropeans in 1873 after they were attracted to nearby regions due to its vast natural reserves ofgold.George Elphinstone Dalrymple, the Queensland Gold Commissioner on theGilbert gold field at that time, was the first European to visit the river and he named the river in honour ofRichard Daintree, an Englishgeologist and the Agent-General for Queensland in London.[1]The Daintree was rated second to theProserpine River, as the river in Queensland where people were most likely to spot asaltwater crocodile from 2000 to 2012, with 145 sightings recorded over the period.[12]
The Wet Tropics of Queensland was given UNESCO World Heritage listing, inclusive of the Daintree River in recognition of "its outstanding natural universal value as an outstanding example representing; the major stages of Earth's evolutionary history, significant ongoing ecological and biological processes, superlative natural phenomena and as containing important and significant habitats for in situ conservation of biological diversity. The river is part of the much larger Daintree Rainforest, region in Northern Queensland encompassing 894,000 hectares (2,210,000 acres).

The river and its surroundings are home to some of the most primitive forms of animal and plant life in the world. The surrounding mountains and valleys provided protection from the forces to adapt to climate change by sheltering several species of plants. A notable example is the primitive She-oakGymnostoma australianum. This pine-like tree is the only remaining species in theGymnostoma group of plants in Australia, and is now restricted to very isolated pockets north of the Daintree River. The genus was once widespread throughoutGondwana, and its relatives are still found in parts of the Pacific and south-east Asia.
Of the five species of ringtail possum found in north Queensland rainforests, thecinereus ringtail possum (Pseudochirulus cinereus) is almost wholly restricted to the Daintree catchment. Within the park, this species is found only in upland rainforest on Thornton Peak and the upper reaches of the Daintree andMossman Rivers. Once considered a light-coloured form of theHerbert River ringtail possum, commonly found throughout theAtherton Tablelands, it was described as a distinct species in 1989. Black and whitestriped possums (Dactylopsila trivirgata) are quite common throughout the park, particularly in the coastal lowlands north of the Daintree River, although to see one while spotlighting requires a mixture of luck and know-how.
Due to the river's isolation,saltwater crocodiles - once threatened in the region due to hunting - have flourished in recent years, beneficiaries of legislation that protects them. There have been numerous reports of deaths in the Daintree River from crocodile attacks.[13][14][15] Authorities warn tourists and visitors not to step close to the riverbank, and stay within the confines of boats, and absolutely never swim in the river.
