The unit's mission was to paddle ashore and reconnoitre the island to determine the status of Japanese defences and validate reports that two 140 mm long-range naval guns were still in position.

[3] On the night of 11 April 1945, eight men were dropped off near Muschu Island with four Hoehn military folboats (collapsible canoes) by HMAS HDML 1321 patrol boat.

[7] The information he returned with proved vital to keeping the guns out of action and in preventing the Japanese from using the island as a launching point for attacks against the Australian forces during the Wewak landings a month later.

[9] On 12 June 2014, the remains of former St George first grade rugby league player, Lance Corporal Spencer Henry Walklate, and Private Ronald Eagleton, were laid to rest with full military honours at the Bomana War Cemetery just outside Port Moresby.

[10] A film based on Don Dennis' book 'The Guns of Muschu' was announced to be in development on April 24th 2024, with a screenplay written by Tom Broadhurst and Jack Brislee to be directed by Matthew Holmes.
