Predicting the effects of contaminant inputs on coastal marine ecosystems has become increasingly important as discharges have increased due to landuse change on watersheds. Coastal pollution from land-based sources and in particular eutrophication are now seen as the principal human threat to coastal seas at a global scale (Correlli, 1998; Carpenter et ai, 1998; Nixon, 1995; Cloem, 2001). To successfully assess the threat to coastal ecosystems from land-based sources of pollution catchment budgets, which determine the relative magnitude of the various sources of contaminants, are necessary. This sort of budgeting has now been carried out in great detail in Europe, North America and the Atlantic Ocean (Howarth et al, 1996; Nixon et al, 1996; De Wit, 2000; Alexander et al, 2002). A similar need is evident for the Great Barrier Reef World heritage Area and its catchment. Such a risk based approach is needed to prioritise catchment management initiatives and compare risk factors within catchments to prioritise works.
