PSSAs and transit passage - Australia's pilotage system in the Torres Strait challenges the IMO and UNCLOS

Abstract

On 22 July 2005, the International Maritime Organization (IMO) approved the extension of the Great Barrier Reef Particularly Sensitive Sea Area (PSSA) to the Torres Strait in Resolution MEPC.133(53). Australia amended its regulations and issued marine orders imposing a compulsory pilotage system in the Torres Strait. Australia's actions triggered protests from maritime states at the IMO and in bilateral diplomatic exchanges. This article examines the legal issues raised by Australia's establishment of a compulsory pilotage system in a strait used for international navigation, including the prospects for Australia being challenged under the compulsory dispute settlement provisions of the UN Convention on the Law of the Sea. It is recommended that the PSSA Guidelines of the IMO be amended to ensure that such legal issues do not arise in the future.
