We assisted the Commonwealth Department of Environment and Energy in compiling non-governmental investments on Great Barrier Reef protection and enhancement for 2013-14 and 2014-15. The study looked at co-contributions to government programs from private landholders, philanthropy investments, research and investments by NGOs. To our knowledge, it is the first attempt at compiling this type of information on the GBR, and follows our previous work for the Department compiling local government investments.
