Cape St. George
"S-44" departed Brisbane on 24 July. Cloudy weather with squalls set in. On 31 July, she commenced patrolling the Rabaul-Tulagi shipping lanes. The next day, she sighted a convoy off Cape St. George, but heavy swells hindered depth control and speed, and prevented her from attacking. From Cape St. George, "S-44" moved up the east coast of New Ireland to North Cape and Kavieng, where she waited.
