All of us live, work, and manage our affairs in what we call a nation or country. We expect to find rivers and river basins, if only the most meagre ones, in all countries. The tiniest amount of rain needs to drain somewhere - unless the soil or sand is so porous that it disappears without trace. Draining water forms a rivulet. A number of rivulets fed by the same rainfall combine to form a proto-catchment or rivulet basin. Australia is a country containing many significant river basins, one large and dominant, plus hundreds of smaller ones. Our challenge, and your challenge, is to imagine life in a river basin as life in an ecologically defined nation. Imagine you live in a catchment. You do your business in a catchment. Your government is formed by voters in the catchment. You trade with people in other catchments. Of course this is all hypothetical; yet imagine how much easier environmental management would be. No intra-catchment negotiations would be required.
