A local landcare coordinator in Central Queensland, Australia is working to promote the Year of Freshwater in local schools. A postcard competition is being organized with all the local schools where students are researching fresh water issues and turning this research into small posters. The winning postcard designs will be published as real postcards, distributed through cafes, cinemas, and public spaces via 'free postcard' stands around Australia. This is both an excellent way of promoting the year and bringing together school children's perspectives.
