This Damien Parer/Ken Hall newsreel was shot at a time remembered as the dark days to Australia's north, with the Japanese still strong and threatening Port Moresby with air raids. The air battle for Port Moresby was a critical time for Australia. From this larger battle the newsreel selects a number of incidents for the visual record, as it looks at the damage to buildings in Port Moresby, the crash landing of an American bomber which had lost its undercarriage, and the sinking of the merchant vessel, the Macdhui, in Port Moresby harbour.
