The two gun 155mm coastal battery at False Cape was established in early 1943 to defend the port of Cairns. Access is via Yarrabah Road and then to the end of the Esplanade (past Second Bay), followed by a 45 minute walk north past Sunny Bay to the tip of False Cape.

Two concrete gun emplacements survive at the tip of the cape. Each has a circular (incomplete circle) concrete mount, with a cantilevered roof and magazine areas to the rear. In addition, a separate concrete magazine is located to the south, with a corridor around three sides of two rooms. A steel anti-aircraft gun mount is located above the magazine.

A two-level concrete Command Post (CP) is situated on the ridge southeast of the gun emplacements and magazine. Above the access road on the west side of the cape is the cutting where supplies were once winched up to the CP, and below the road there is a pathway to the site of the stone jetty.

Evidence of the camp site at Sunny Bay, where huts were located to the north and south of Sunny Creek, include some concrete slabs and a concrete road culvert over Sunny Creek. A concrete rainwater tank is located on the ridge midway between the former camp site and the cape.
