Legal implications of Australia'S Maritime Identification System

On 14 December 2004, Australia announced the institution of a 'Maritime Identification Zone', extending 1000 nautical miles from its coast and involving the identification of vessels seeking to enter Australian ports, as well as vessels transiting Australia's Exclusive Economic Zone. This Article analyses the legality of these security measures under the UN Convention on the Law of the Sea, new developments through the International Maritime Organization and the Proliferation Security Initiative. The implications of prescribing and enforcing identification requirements on the high seas and in the EEZ, the impact on maritime boundaries and avenues for dispute settlement are all explored.
