The Mary River is a river system in South East Queensland, Australia. The river rises at Booroobin in the Sunshine Coast hinterland, west of Landsborough. From its source, the Mary River flows north through the towns of Kenilworth, Gympie, Tiaro and Maryborough before emptying into the Great Sandy Strait, a passage of water between the mainland and Fraser Island, near the town of River Heads, 17 km south of Hervey Bay.

The river's catchment covers an area of 9595 km² and is bounded by the Conondale, Jimma and Burnett Ranges.^[1] Major tributaries of the Mary River include Tinana Creek, Munna Creek, Obi Obi Creek, Yabba Creek, Wide Bay Creek and the Susan River.

The endangered Mary River Turtle (Elusor macrurus) lives in the river.^[2] Other marine life native to the river include the Queensland Lungfish (Neoceratodus forsteri) and the endangered Mary River Cod (Maccullochella mariensis). Significant vulnerable and endangered species that live in the river also include endangered Giant Barred Frog, Cascade Tree Frog and Coxen's Fig Parrot and the vulnerable Tusked Frog, Honey Blue-eyed Fish, the Richmond Birdwin Butterfly and the Illidge's Ant-blue Butterfly.

The River was traditionally named Moocooboola by local Aborigines (the Kabi Kabi people). The river was subsequently named Wide Bay River by early European explorers. The official name was changed in 1847 (prior to Queensland becoming a separate colony) by Charles Augustus FitzRoy, then Governor of New South Wales, to Mary River — after his wife Lady Mary Lennox.^[3]

It is also a historical Australian river that contains gold as was first discovered in Gympie by James Nash.

Traveston Crossing Dam

Main article: Traveston Crossing Dam

In light of the region's longest drought in one hundred years, the Queensland Government announced on April 27, 2006 its intention to dam part of the Mary River at Traveston Crossing, south of Gympie. The project was cancelled in November 2009, after being refused approval by federal Environment Minister Peter Garrett.

The action had been planned to create a reservoir "almost as big as the Wivenhoe Dam" ^[4] by 2011. The Traveston Dam was projected to inundate an area of fertile farmland, endangered regional ecosystems and small towns more than 1.3 times the area of Sydney Harbour ^[5]. There was considerable local opposition to the proposal, with all Mary Valley and Sunshine Coast Shire Councils opposed to the dam proposal ^[6] on a variety of grounds including: the dislocation of the local community from the inundated area; adverse effects on downstream communities; and environmental impacts such as the removal of one of the few remaining habitats for the vulnerable Queensland Lungfish ^[7]. More than 20,000 residents formally petitioned the Queensland State Parliament to halt the dam. There were further concerns that the geomechanics of the proposed site were not suitable for damming due to potentially significant leakage (due to the predominantly sandy substrate) and evaporation problems.^[8]

There was strong opposition to the dam from the wider and international community, based on environmental concerns related to the endangered Mary River Cod, Mary River Turtle, Giant Barred Frog, Cascade Tree Frog, Coxen's Fig Parrot, the vulnerable Queensland lungfish, Tusked Frog, Honey Blue-eyed Fish, the Richmond Birdwing Butterfly and the Illidge's Ant-blue Butterfly.^[9] There were also fears for the Dugong, a globally vulnerable species. It was alleged that reduced fresh water flowing to the Great Sandy Strait would have affected the growth of seagrass, the Dugong's primary food source.

The Mary River Turtle and the Queensland Lungfish attracted particular attention regarding their conservation. The Mary River Turtle, whose only known home is the Mary River, is a cloacal ventilator ('bum breather' - it uses oxygen from water taken in through its tail), and is listed in the top 25 most endangered turtle species in the world. The Lungfish also has great significance to evolutionary biologists. It requires the rapids in order to breed, and much of its breeding habitat had already been interrupted by other dams in Queensland. Professor Jean Joss of Macquarie University stated, in a submission to the Senate Inquiry 2007: "The Mary River dam would almost certainly push the lungfish to 'Critically Endangered,' and in the long term will lead to its extinction in the wild." The Mary River Cod, which only lives naturally in the Mary River system, is already Critically Endangered. It is completely protected, and it is illegal to fish them.

The Mary River flows into the Great Sandy Strait, near wetlands of international significance recognised by the International agreement of the Ramsar convention and Fraser Island World Heritage Area, which attracts thousands of visitors every year.

2011 floods

The Mary River experienced major flooding during the 2010–2011 Queensland floods. In some places the river rose 20 m.^[10] In Maryborough the river peaked at 8.2 m while at Gympie the peak was 19.3 m. The Bruce Highway was closed to the north and south of Gympie^[11] and more than 50 homes and businesses were inundated.^[12] The high turbidity levels interfered with the natural breeding cycle for some of the river species.^[10]
