In January 1967, the destroyer was again deployed to the FESR. As the Confrontation had concluded, the deployment was characterised by fewer patrols and more exercises and port visits. During the six-month assignment, "Duchess" called into Telok Kekek, Pulau Langkawi, Pulau Song Song, Bangkok, Hong Kong, and Singapore. She returned to Sydney on 17 June and docked for refits. On 12 October, the four-year loan of the ship was extended to April 1972. The refit concluded on 3 June 1968, and the destroyer was assigned to multinational exercises; first with the Royal New Zealand Navy off Auckland, then with British, New Zealand, and American units in the Solomon Sea. "Duchess" was then deployed to the FESR, and arrived in Singapore on 10 October. A program of port visits was interrupted in November by the need to escort "Sydney" on her twelfth Vietnam voyage. On 18 November, "Duchess" met "Sydney" off Singapore, and accompanied the troopship to and from the warzone, before sailing to Hong Kong. Official visits to ports in South Korea and Japan followed, with "Duchess" back in Hong Kong for the Christmas-New Year break. January and February 1969 saw the destroyer travel as far east as Pakistan. The destroyer returned to Singapore on 25 March, via Thailand and Hong Kong, then after a short exercise period, the destroyer headed for Sydney. Maintenance and local exercises dominated the ship's schedule until November, when she headed north to escort "Sydney" on the latter's fifteenth voyage. After reaching Vũng Tàu on 28 November, then escorting the troopship from the warzone, "Duchess" peeled off to commence another FESR deployment. After a short maintenance period in Singapore, the destroyer visited Subic Bay, then headed to Hong Kong for the end of the year.
