The Darwin Harbour Region is home to more than half of the Territory's population. The Harbour and its waterways are of social, economic, environmental and cultural importance for local communities, governments and industries. It is around 7 times larger than Sydney Harbour and is mostly lined with mangrove forest, providing a rich habitat for a diversity of marine life. The Harbour also supports the Territory's largest concentration of commerce and industry. Continued growth of the city and rural areas will place the Harbour under increasing pressure .
Each year the Northern Territory Government produces Darwin Harbour Region Report Cards which provide a snapshot of water quality and the health of aquatic ecosystems across the Harbour and its catchment.
The Water Quality Protection Plan for Darwin Harbour is one element of a broader coordinated approach to Darwin Harbour management, monitoring and research.
The Darwin Harbour Strategy is a guide for the responsible stewardship and sustainable development of the Darwin Harbour region. The Strategy's purpose is to provide policy and decision makers within government, industry , commerce and the community with guidance for the integrated management of the Darwin Harbour region's diverse environmental, social, cultural and economic values and uses.
