Hi, I'm John Sinclair. For the past 44 years I've been the leading advocate to protect the outstanding universal value of Fraser Arnd. The first major battle for my organisation, the Fraser Arnd offender's organisation, was stopping the most destructive sandwining industry. That fierce campaign lasted for six years, but in the end we won. The next battle was the getting world heritage recognition for this amazing natural wonderland, and it was even tougher, and that battle lasted for the next 14 years. The problem was stopping the logging industry which had become entrenched over the previous century. While fire days still involved in advocacy, especially managing Fraser Arnd tourism to make it sustainable, we've had to dramatically change our tactics to ensure that the natural integrity of the world's greatest sand island is stronger. The sand island is preserved. Simply gaining a title of National Park and World Heritage doesn't mean itself remove threats to the integrity. On Fraser Arnd, there are many insidious threats that resolve starved government agencies can't manage on their own. The threat from invasive species, particularly alien weeds, is a major threat to the stunning natural forests. Few small urban settlements are centres of most major weed infestations. Most weeds are gardened escapees. It is important to control these weeds before they escape into the surrounding National Park, where control becomes more difficult or impossible to patrol. Father is now actively engaging volunteers from all around Australia to help control these threats to the natural integrity. It has developed collaborations with the park services, local government, local land holdings, the tourist industry, and other agencies to reduce and eliminate injured breeds. Fraser Arnds, outstanding natural beauty and recreational opportunities, attract about 350,000 visitors annually, almost all traveling by four-wheel drive vehicles. Father estimates that in heavy rainfall events, this causes about one tonne of sand for each visitor to the island to be slewced on slopes, some of it ending up in some of the iconic Perch June lakes. Father is engaged in the long term project attempting to measure the full impacts of this forward drive activity. Father believes that it is important to change the patterns of recreation on Fraser Island to rely on much less on forward drives. With other voluntary conservation groups and with the support of the Queensland Parks and Wildlife Service, we are actively extending the existing walking track system on Fraser Island. We are also championing a light rail people mover to the island to stop send disturbance on the roads. The new walking track infrastructure includes Tyker Open Night Shelters, when it is complete, because of the attractiveness of the features encountered, Fraser Island's subtropical climate and conditions conducive to walking at any time of the year, it is confidently expected that the Georgia Tech track will become the most popular long distance walk. Apart from action in the field, we have used volunteers to help Father stage banal Fraser Island conferences and assist in hosting a team of international peace specialists to study the unique trends of Fraser Island. These along with our regular implemented background is, are helping provide a wider public appreciation of the islands ascending universal value. Father believes that volunteers increase their commitment to Fraser Island through walking on their projects. Thus, while other kids become volunteers because of their commitment, volunteers can also become advocates as a result of their first hand experiences and increased commitment, volunteering as best sets that assist and improve park management in many ways.
