The opposition council has criticised Brisbane City Council for jumping the gun in claiming victory after the development application for the controversial Mt Coot-tha zipline project was approved, because they’re still awaiting approval by the state government.

The three-stage zipline would include a 1.5-kilometre treetop canopy tour, a skywalk with a 335-metre suspension bridge and the scenic zipline tour with six lines travelling more than a kilometre from the summit’s lookout to the Botanic Gardens.

More than 3600 submissions were sent to council during the assessment process, with about 90 per cent objecting to project, claiming it will cause ecological degradation.
