24 Australia Pub. 120 Maritime Claims The maritime territorial claims of Australia are, as follows: Maritime Boundary Disputes Australia and East Timor agreed (2005) to defer the disputed portion of their boundary for 50 years and to split hydrcarbon revenues evenly outside the Joint Petroleum Development Area covered by the 2002 Timor Sea Treaty. This dispute hampers the creation of a revised maritime boundary with Indonesia in the Timor Sea. Indonesian groups have challenged Australia’s claim to Ashmore Reef (12°15'S., 123°03'E.) and Cartier Island (12°32'S., 123°32'E.). Offshore Drilling Petroleum exploration rigs and production platforms may be encountered off the coasts of Australia. The main areas of activity are in Bass Strait and off the NW coast of Australia. Isolated rigs may be encountered anywhere. Safety zones extend a radius of 500m around fixed structures. Only authorized vessels may enter the safety zones. Drill rigs are moored within a ring of large anchor buoys; this ring may exceed a diameter of 1 mile. The anchor buoys are unlit and may not give a good radar return. When there is sufficient sea room to do so, vessels should not pass within 2.5 miles of exploration rigs or production platforms, giving sufficent allowance for prevailing weather conditions and the possibility of engine, steering, or other mechanical failure. Pilotage New South Wales Pilotage is compulsory for New South Wales. The pilotage service is under the control of the Maritime Services Board of New South Wales. Queensland Pilotage into Queensland ports is compulsory. It is under the control of the Queensland Department of Harbors and Marine. Queensland Coast and Torres Strait Pilots are licensed only for coastal pilotage. Vessels that are exempted in New South Wales and Queensland include all naval vessels, interstate vessels, or coasters, whether under power or sail, and being under 50 nrt. Regulations are in force in Australian waters concerning use and design of pilot ladders and mechanical pilot hoists. Great Barrier Reef/Torres Strait Pilotage is compulsory for vessels 70m in length or longer and for all laden oil tankers, chemical carriers, and LNG carriers when navigating through the Inner Route of the Great Barrier Reef between Cape York (latitude 10°41'S.) and Cairns Roads (latitude 16°40'S.), when passing through Hydrographer’s Passage, when passing through Whitsunday Passage, when passing through Torres Strait, or when passing through Great North East Channel. Further information can be found in paragraph 7.2 and paragraph 9.4 in Pub. 127, Sailing Directions (Enroute) East Coast of Australia and New Zealand. Pollution Insurance Requirements All vessels 400 gross tons and over carrying oil as cargo or bunkers must have a “relevant insurance certificate” when visiting an Australian port. This requirement does not apply to oil tankers already required to have insurance under the International Convention on Civil Liability for Oil Pollution Damage 1992. The “relevant insurance certificate” must contain the following information: 1. Vessel name. 2. Owner’s name. 3. Name and business address of insurance provider. 4. Commencement date of insurance coverage. 5. Amount of coverage provided. Further information on these requirements can be obtained from Environment Protection Standards of the Australian Maritime Safety Authority (AMSA), as follows: 1. Telephone: 02-6279-5007 2.

Australian Customs Service’s Form 13 (Ship Pre-Arrival Report) can be obtained from the Australian Customs Service web site, as follows: New South Wales Vessels on arrival at any port in New South Wales should obtain a copy of the port regulations. Regulations have been made for navigation of the navigable rivers in the area of New South Wales. A vessel approaching any dredge, or other vessel employed on any works in the river, is to reduce speed to a rate not exceeding 4 knots over the ground when at least 275m away and so continue until the vessel has passed 45m beyond the dredge or other vessel. All vessels passing such dredges or other vessel must pass on the side indicated by the signals from the dredge. When a vessel is being docked or undocked in the rivers, a red flag is displayed at the entrance to the dock. All vessels approaching must proceed at dead slow speed when at least 275m off the flag, and so continue until 45m past it. A vessel approaching a ferry shall, when between 0.5 mile and 0.25 mile from the ferry, sound a prolonged warning blast on her whistle or siren, and slow down. If the ferry is underway the vessel should pass astern of or behind the ferry, and if practicable, stop engines when passing over the wire of the ferry to avoid fouling it. Ferries are forbidden to leave the shore after a vessel has sounded a prolonged warning blast until the vessel has passed. Ferries and other vessels working on wires or chains in ports or across navigable rivers exhibit, at each end, an all around red light, not less than 3m above the deck and visible at a distance of 1 mile. A similar green light is located not less than 1m above the red light, at the forward end of the vessel, to indicate the direction of travel. Speed limits between 4 and 8 knots are in force on many rivers and lakes in New South Wales. Special regulations are in force regarding the carrying, loading, and discharging of explosives. The information below has been extracted from the regulations made under the Explosives Act, 1905 (New South Wales). At ports in New South Wales, vessels with explosives on board, other than ships’ stores not exceeding 50 pounds in weight, must furnish a full report of the same to the local authorities immediately on arrival in port. At Newcastle, report to the harbormaster, at any other port or place, report to the local police inspector, or if there is no inspector, to the principal officer of Customs at such port or place. Vessels having explosives on board must anchor in the anchorages set apart for them. Queensland Vessels on arrival at any port in Queensland should obtain a copy of the port regulations. The following sound signals are in force in Queensland rivers: 1. The master of every powered vessel shall, immediately before casting off from any wharf or jetty in any river in Queensland, signify his purpose to do so by a prolonged blast on the whistle or siren. 2. The master of every powered vessel proceeding up any river in Queensland and approaching any bend shall sound on the whistle or siren a short blast followed by a long blast. The master of any vessel proceeding down any river and approaching any bend shall sound on the whistle or siren a long blast followed by a short blast. 3. When a powered vessel underway in any river in Queensland is about to turn around, the master shall signify such purpose by four short blasts on the whistle or siren followed, after a short interval, if turning with its head to starboard, by one short blast and, if with its head to port, by two short blasts; and, while such vessel is turning shall repeat such signal to any approaching vessel; the master of the latter vessel shall take action to avoid collision. Powerdriven ferries operating across Queensland rivers, exhibit a green light visible all-round the horizon, at each end of the vessel. 4. In the Brisbane River, when such vessels are underway, they exhibit an additional red flashing light visible all-round the horizon, from a position midway between the center of the ferry and the forward green light. Speed.—Every powered vessel when underway within the limits of any port in Queensland, shall be navigated at such reduced speed as to not endanger the safety of any other vessel or vessels or moorings, or cause damage thereto, or to the banks of any river, or to any wharf, jetty, dredged channel, beacon, buoy, or other harbor improvement. When passing a berthed container vessel with the portainer boom in the lowered position, vessels should approach at the minimum possible speed and if possible, stop their engines when passing. Vessels with drafts over 2m must not exceed the prescribed speed limits for the various ports. Customs.—The Collector of Customs has appointed certain stations for the boarding or landing of customs officers at the various ports in Queensland. The signal to be shown for stopping vessels at such stations shall be “SQ” of the International Code of Signals, or a red light at night. Explosives.—Vessels carrying explosives in excess of 20 pounds are forbidden to proceed beyond certain points at ports in Queensland.
