The Australian Hydrographic Office (AHO) is the national authority responsible for delivering hydrographic products and services to meet the demands of the maritime community in line with national and international obligations. These international obligations are reflected in Australian domestic law under the Navigation Act 2012 and the Marine Safety (Domestic Commercial Vessel) National Law Act 2012.
Under agreements between governments, Australia is the Primary Charting Authority (PCA) for Papua New Guinea and Solomon Islands. The AHO is currently in the process of establishing a long-term agreement with the government of Timor-Leste to support and develop their hydrographic and charting activities.
ChartScheme is the AHO yearly charting plan. It details planned activities within Australian waters and in waters of countries for which the AHO is the PCA.
