Fort Pearce is a former defensive facility occupying part of Point Nepean, Victoria, Australia. It was part of a network of fortifications, commanded from Fort Queenscliff, protecting the narrow entrance to Port Phillip.
The fortifications were constructed between 1910 and 1916. Two open concrete gun pits for Mk VII guns were constructed in 1911 with a large underground magazine between the pits. A battery observation post and direction range finder were constructed above the magazine. The gun crews were based at nearby Fort Nepean.
At the outbreak of World War I, additional men of the Royal Australian Garrison Artillery and Royal Australian Engineers were posted to Fort Nepean. Additional barracks were constructed at Fort Pearce and were named Pearce Barracks. The barracks consisted of officers' quarters, two huts for the NCOs and men, ablutions hut, a cook house and store, mess, office, workshop and parade ground. Some of the timber huts were clad with sheets of iron to protect against machine gun fire.
The guns at Fort Pearce never fired in anger. The only fatality at the fort was Gunner Walter Hargrave, who was killed when one of the guns misfired on 16 July 1916.
Additional huts, a fuel store and a larger ablutions block were constructed at Pearce Barracks in 1939–1940. Machine gun and mortar pits were dug into the sand dunes around the fort and manned throughout the war by the 2nd Battalion Volunteer Defence Corps.
