It is situated at the south western end of Camden Sound and surrounds Yawajaba (Montgomery) Island.

[4] It lies within the Camden Sound Marine Park, which was gazetted in 2012, covering an area of 7,062 square kilometres (2,727 sq mi).

When the tide is out, vast lagoons, sandstone islets, and a central mangrove island are revealed.

The outward movement of the tide forms a torrent of water, creating a river cutting through the reef and hundreds of cascading waterfalls.

While the tide is going out, the waterfalls attract migratory wading birds, feeding turtles, manta rays, black tipped reef sharks, and dugongs.
