Not only did the installers of a new-recycled plastic staircase, at Coomba Falls in Queensland, have the steep terrain and granite cliffs to contend with, but they also had to be mindful of the native grass trees. Some of these trees are extremely old with one of the largest estimated to be aged approx. 550 years. Any interference with one of these could result in a $50 000 fine. While the staircase presented many challenges it now extends 120 metres, improving access to the Falls while also protecting these significant trees.
