In 2006 rangers on Fraser Island trialled using recycled-plastic decking to see how it would compare with timber when used for four wheel drive beach access. Over the last six years approximately 30,000 four wheel drive vehicles have travelled over the plastic and yet it is still the same as the day it went in. Among these vehicles are 18-tonne four wheel drive busses—at least 10 per day—proving just how tough the decking is. According to the rangers the timber sections that were installed at the same time have deteriorated and they have now made the decision to replace them with recycled plastic.
