s is a new AMSA responsibility. AMSA maintains two
shipping registers. Ships registered on an Australian shipping register have
Australian nationality for international
shipping law purposes. Unless otherwise exempt, Australian owned ships are required to be registered on the general or international shipping register if it is a domestic commercial vessel, 24 metres or over in tonnage length, capable of navigating the high seas, or any vessel travelling overseas. Vessels engaging in international trading that are at least 24 metres in tonnage length and wholly owned or operated by Australian residents, or by Australian residents and Australian nationals may apply to be registered on the international register. There are tax incentives for ships on the international register to make the register competitive with other registers, such as vessels being operated with mixed crews, with the majority of officers and crew not being required to be Australian citizens or residents. AMSA has delegated certain survey and certification functions to a number of recognised
classification societies, which are members of the
International Association of Classification Societies. The
Council of Australian Governments (COAG) in 2011 directed AMSA to work co-operatively with the states and territories to create a national system for domestic commercial vessels, including any changes to Commonwealth, state and territory laws and administrative arrangements of the parties that are necessary to facilitate the reform. The new legislation came into effect in 2013, and the transition to the new system was completed in July 2018. == Emergency towage vessel capability ==
