Hugh Randall Syme, GC, GM & Bar (20 February 1903 – 7 November 1965) was an Australian naval officer, bomb disposal operative, and newspaper proprietor.

He was a keen amateur yachtsman and part-owner of an 82-foot (25 m) yacht, and joined the Royal Australian Naval Volunteer Reserve on the outbreak of war.

The most important was in November 1942 at Weston-super-Mare, Somerset, where he defused a new mine known as a Type T. He had to hang upside down in a mudhole and endure painful electric shocks while insulating the wires for the detonator.

The story of his wartime service was told in Softly Tread The Brave – A triumph over terror, devilry, and death by mine disposal officers John Stuart Mould, GC, GM and Hugh Randal Syme, GC, GM and Bar, and Seventeen Seconds – The gripping true story of the men who dismantled live Nazi bombs in England during World War II, both by Ivan Southall.

Hugh Syme died on 7 November 1965 from a cerebral tumour at Epworth Hospital, Richmond, and was cremated with Anglican rites and full naval honours.
