The area is defined by a line:
(a) commencing at a point on the coast of Australia in latitude 11° 00' South,
longitude 142° 08' East;
(b) running thence north-westerly along the geodesic to the point of latitude
10° 28' South, longitude 141° 20' East;
(c) thence north along the meridian of longitude 141° 20' East to its intersection by
the parallel point of latitude 9o 33' South;
(d) thence north-easterly along the geodesic to the point of latitude 9o 13' South,
longitude 141o 57' East;
(e) thence north along the meridian of longitude 141o 57' East to its intersection by the
southern coastline of the island of Papua New Guinea at low water;
(f) thence generally easterly along the southern coastline of the island of
Papua New Guinea, that is along the low water line on that coast and across any
river mouth and in the case of the mouth of the Mai Kussa River along the parallel
of latitude 9o 09' South, thence along the southern coastline of the island of
Papua New Guinea, that is along the low water line on that coast and across any
river mouth to its intersection by the meridian of longitude 142o 36' East;
(g) thence south along that meridian to its intersection by the parallel of latitude
9o 21' South;
(h) thence north-easterly along the geodesic between that point of intersection and the
point of latitude 9o 09' South, longitude 143o 47'20" East;
(i) thence along the outer limit of the three-mile territorial sea of Black Rocks, so as
to pass to the north-west of Black Rocks, to the point of intersection of that limit
by the outer limit of the three-mile territorial sea of Bramble Cay;
(j) thence along that outer limit, so as to pass successively to the north and east of
Bramble Cay, to the point of latitude 9o 08'30" South, longitude 143o 55'57" East;
(k) thence north-easterly to the point of latitude 9° 00' South, longitude 144° 30' East;
(l) thence generally southerly along a line joining the following geographic positions:
a. 10° 41' S 145° 00' E
b. 13° 00' S 145° 00' E
c. 15° 00' S 146° 00' E
d. 17° 30' S 147° 00' E
e. 21° 00' S 152° 55' E
f. 24° 30' S 154° 00' E
(m) thence westerly along the parallel of latitude 24°3 0' South to its intersection by
the coastline of Queensland at low water; and
(n) thence generally northerly along that coastline at low water to the point of
commencement.
