Part of a large estuary along the eastern Australian coastline (150 kms north of Sydney, NSW) used for shellfish production has been closed to harvesting for over 18 months. Monitoring has shown viral contamination of oyster tissue on a number of occasions and surveys of drainage channels and the estuary indicate regular exceedances of bacterial standards set for shellfish growing waters, particularly following heavy rainfall. The contamination has been attributed to urban runoff, agricultural wastes and possibly failing on-site wastewater systems.
