[2] In April 1950 St Austell Bay and sister ship Veryan Bay exchanged with the Royal New Zealand Navy frigates Hawea and Taupo, arriving at Auckland on 3 July to join the RNZN 11th Frigate Flotilla for exercises, patrols and visits in the Pacific, finally returning to the flotilla at Malta on 4 January 1951.

[2] In March she returned to the UK for service in the 7th Frigate Flotilla, Home Fleet, and almost immediately took part on the search for the missing submarine Affray.

[2] In June 1952 she arrived at Hamilton, Bermuda, to join the America and West Indies Squadron, and in July was sent to Port Stanley to act as Guardship in the Falkland Islands.

In October she left the Falklands and sailed up the west coast of South America, making calls at Puerto Montt, Valparaíso and Antofagasta in Chile, and Callao in Peru, before transiting the Panama Canal, and returning to Bermuda in December.

[2] St Austell Bay was recommissioned in May 1955, but significant problems with the refit delayed deployment until November when she returned to Bermuda for the usual programme of joint exercises, training and port visits in the Caribbean and to North America.
