I have been volunteering with Environment Victoria for years to help protect Victoria's environment. I get no personal benefit (I am a volunteer) but thought this may be of interest to both locals, and interstate or international tourists...
In October 2016, EV is running an awareness and fundraising campaign for our rivers. If five days of paddling on the Goulburn and Murray Rivers with passionate, like-minded people, while raising funds to protect Victoria’s rivers, sounds exciting and beautiful, then read more about it here: https://inspiredadventures.com.au/events/environmentvicpaddle2016/
