Basalisk Battery is located to the west of Port Moresby, overlooking Fairfax Harbor, Idlers bay and Fisherman's
(Daugo) Island. Accessible by road via Roku or by boat from Idlers bay. Also known as Basalisk Fortress or Basalisk Gun Fortress.
Built during April to August 1944, by the Australian Army,
8th Army Troops Company. This Battery had emplacements for three 5.25" Mark
II guns, but only two guns were installed. Gun No. 1 was built first and Gun no. 2 was completed on August 17, 1944. An observation post
was built on the hilltop surrounded by three gun emplacements. On the reverse slope bunkers for ammunition storage, generators and accommodation were built.

Gun No 2
This mount is located furthest to the west. There
is a underground armory and a generator room behind the gun. The battery is empty, although the concrete mounting plate for the generator
is still present in that room, and the metal railing for the stairs leading downward.
A large concrete bunker dominates the top of the hill. It has several
rooms areas, and from its roof offers commanding views of the two gun
areas, and also a view port for firing small arms at anyone approaching
from the seaward side. All rooms are empty.
Bunkers B29, B30, B31
There are three rectangular buildings on the reverse slope of the hill,
these buildings have B29, B30 and B31 painted on their exteriors. B29
and B31 have large windows and doorways. B30 is the largest, and has
only one doorway for entry, and a ventilation system, probably this
one was for shell storage. All these buildings are empty.
After the war, the guns were removed and the battery abandoned.
Basalisk Battery remains intact.
