The problems with Mountain Bike and Adventure Tourism is a state-wide, Australia-wide and World-wide problem. Because of this we are preparing information for those who are struggling with mountain bike proposals on these levels too.
This article gives an indication of how wide spread the development of Mountain Bike Destinations are in Victoria. This spread is also Australia Wide and comes from the Federal Governments plan to turn Australia into an Adventure Tourism Capital. The Federal Government has released funds to states on the basis that they and local councils go in thirds on any destination developed. So the states have sent DELWP and Parks Victoria out to find Adventure Tourism opportunities. This is not grass roots driven.
