Bowen Island (Jervis Bay)

The island, however, is not part of the state of New South Wales but of the Jervis Bay Territory, administered by Australia's federal government.

[1] In the 1990s it was raised as a prospective site to establish an internment camp for drug users to recover from heroin addiction.

It slopes sharply from the cliffs on its eastern, or oceanic, side down to rock platforms at sea level on its west.

The island, with the waters on its western side, constitutes a special purpose zone intended to protect nesting seabirds and their habitat from disturbance, and is not open to general public access.

A single QF 4.7-inch Mk 1 was emplaced, and a jetty, several buildings, a concrete command and observation post and an underground ammunition magazine were constructed.
