Koala populations in Queensland could be threatened by an adventure ride proposed to boost tourism in a Queensland national park.
Environmentalists say trees that will support the cable based zipline planned for Obi Obi Gorge in Kondilla National Park, in the Sunshine Coast hinterland, are koala habitats.
National Parks Association of Queensland executive coordinator Paul Donatiu says building steel platforms, required to suspend the adventure ride, and the clearing of vegetation for the cables would harm the habitat and rare bird species as well.
"This government is ignoring its duty of care to conserve rare species in our national parks, including koalas, in the name of adrenaline tourism," Mr Donatiu said.
