Great Barrier Reef location

The Great Barrier Reef location is, for most, on the other side of the world!

Where is the Great Barrier Reef? you ask.

Well it is located off north-eastern Australia and runs more or less parallel to the coastline of the state of Queensland.

In terms of latitude, the northern end of the Great Barrier Reef Marine Park and World Heritage Area start together at 1040'55"S and run south until 2429'54"S, spanning the Tropic of Capricorn - the line of latitude 2330' south of the Equator.

Defining the boundaries

The Great Barrier Reef Marine Park and the Great Barrier Reef World Heritage Area differ slightly in terms of exact boundaries - the latter is approximately 2600 square kilometers larger simply because the GBR World Heritage Area takes in a few small parts of the Queensland coast too, such as inlets and coves, whereas the GBR Marine Park covers just the area of sea.

The approximate area size figures are:

Great Barrier Reef Marine Park - 345,400
World Heritage Area - 348,000

The boundaries of the Great Barrier Reef World Heritage Area extend from the low-water mark on the mainland cost of Queensland out to the Continental Shelf of the South Pacific Ocean, and just north of Fraser Island at the southern end to the tip of Cape York which is Australia's northernmost point.

Although this is where the World Heritage Area ends, the Great Barrier Reef itself continues northwards for a few hundred kilometers, up towards Papua New Guinea.
