The Australian Hydrographic Service currently has over 400 paper charts. All our charts are fully corrected and update to date with the latest Notices to Mariners. The Australian Hydrographic Service was established, and assumed responsibility for hydrographic surveys in Australia, in 1920. In 1946, Cabinet decided that the Royal Australian Navy (RAN) would maintain the national responsibility for hydrographic surveying, nautical charting and the provision of hydrographic services. RAN is responsible for meeting Australia's obligations to provide hydrographic services as required by the International Convention for the Safety of Life at Sea (SOLAS). Its traditions and methods take their origins from those of the Royal Navy and the pioneers of hydrography.
