After completing training at Whale Island Farncomb was transferred to Woolsher, a small craft attached to the destroyer force at the Firth of Forth.

Admitted to the Bar on 6 June 1958, he developed a reasonably busy practice in Sydney and subsequently joined the solicitors, Alfred Rofe & Sons.

His ashes were scattered at sea on 2 March from the flight deck of his last flagship, HMAS Sydney, off the coast of Western Australia.
