Systems of Buoyage in Australian Waters

There are two systems applying for Australian waters. One for ports and coastal waters which follows the IALA (International Associations of Lighthouse Authorities) System A of buoyage and one for inland waters. Generally lakes and rivers follow the system for inland waters but there are some variations between stats and sometimes combinations of both coastal and inland systems are used.
