after graduation, Power was called to the bars of the High Court of Australia and Supreme Court of Queensland in 1955, where he began his career as a barrister-at-law. In 1965, he moved to Hong Kong and became a magistrate of the Lands Tribunal. He managed to get promoted as President of the Lands Tribunal in 1976. In this capacity, he had compiled the Lands Tribunal Law Reports for three consecutive years, before getting promoted again as a puisne judge of the Supreme Court in 1979. During serving in the Supreme Court, Power was appointed by the government in 1984 to chair the Broadcasting Review Board. Under his chairmanship, the committee published a report in 1985 which resulted in the establishment of the Broadcasting Authority in 1987. In 1987, Power became a judge of the Court of Appeal, a post he had held until 1993 when he was appointed Vice-President of the Court of Appeal. From 1994 to 1997, he was also the chairman of the editorial board of the Hong Kong Law Reports. In 1996, Power was appointed acting Chief Justice of the Supreme Court when Sir Ti-liang Yang resigned and contested for the election of the Chief Executive. He did not hold the post for long and was soon succeeded by Andrew Li as Chief Justice of the Court of Final Appeal immediately after the transfer of sovereignty of Hong Kong from Britain to the People's Republic of China in 1997. The end of British rule bought many changes to the judicature of Hong Kong. A Court of Final Appeal was set up to replace the British Judicial Committee of the Privy Council, and the Supreme Court was renamed the High Court, and Power was appointed a non-permanent judge of the Court of Final Appeal in addition to his original post as Vice-President of the Court of Appeal. Justice Power retired from the Court of Appeal in July 1999 but continued to serve in the Court of Final Appeal. In 2005, he was one of the judges of the Court of Final Appeal who heard the inheritance dispute between local business tycoon, Nina Wang, and her old aged father-in-law. The case was one of the longest civil trials in the legal history of Hong Kong. The court finally overturned the previous High Court rulings and found in favour of Nina Wang.
