The area of Queensland is based on the GEODATA 100K Coastline database, 1993. Albers Equal Area projection was used to calculate areas:

False Easting: 0.000000, False Northing: 0.000000

Central Meridian: 146.000000, Standard Parallel_1: -12.00000,

Standard Parallel_2: -26.00000, Latitude of Origin: 0.000000

The Geoscience area figures are based on the GEODATA 100K Coastline database, 1993. Albers Equal Area projection was used to calculate areas - Standard Parallels: 18 & 36 degrees south and Central Meridian: 132 degrees east on the Australian Spheroid.

The adjacent area of Queensland is determined under the Petroleum (Submerged Lands) Act 1967. Figures include water area around Torres Strait Islands and reef islands but not Coral Sea Islands.

[3] The marine areas are referred to as coastal waters. This is a belt of water between the territorial sea baseline (usually the low water line along the coast) and a line three nautical miles (5.5 kms) seaward of the baseline.

[4] The median point was calculated as the midpoint between the extremes of latitude and longitude of the continent.

[5] Fraser Island is also the world's largest sand island.

[7] Australia is considered to be a continental landmass. However, it is also referred to as the  'The Island Continent'
