Film of action at Milne Bay, which was an almost completely Australian operation and one that dealt a blow to Japanese strategy.

The film begins by showing ships pouring in supplies. Inland are the first traces of invasion - Japanese tanks are wrecked by anti-tank rifle fire. Deeper in the jungle AIF patrols move closely because isolated parts of Japan still resist and have to be mopped up. The enemy was located and the film shows much equipment being captured. The bullet-proof vest, gas mask, helmet and two-toed rubber shoes are shown. Dozens of snipers were shot out of tree tops and the fighter pilots' contribution to the success of the operation was great. The film indicates a party embarking on a trip up the coast to nip out any who are remaining and shows the invasion barge in which the Japanese landed, which carries about sixty men and is made of steel. The film concludes by stressing that Milne Bay was a blow to Japanese strategy.
