After promotion to sub-lieutenant in December 1969, Lord undertook courses at Britannia Royal Naval College in the United Kingdom from early 1970.
He returned to Australia later that year and was appointed to the guided missile destroyer HMAS Brisbane, and saw active service during the ship's deployment on the 'gun-line' in Vietnamese waters during March–October 1971.
He was promoted lieutenant in November 1971 and became the Executive Officer of the patrol boat HMAS Aitape operating in Papua New Guinea waters.
The ship took part in Operation Morris Dance following the military coup in Fiji that year and was standing by to evacuate Australian nationals if required.
