He captained a strong South African XI to an important victory against the Australian touring team early in December 1966, then made his highest score, 222 for North-Eastern Transvaal against Western Province a few days later. Under the captaincy of Peter van der Merwe (who in 1965 had named his son Trevor after Goddard) he played all five Tests against the Australians, scoring 294 runs at 32.66 and having his most successful series with the ball, taking 26 wickets at 16.23. After the Australian second innings in the First Test, when he took his best Test figures of 6 for 53 to give South Africa its first-ever Test victory over Australia in South Africa, he was carried off the field shoulder-high by the jubilant crowd. Asked why the Australians had found Goddard's deliveries so hard to play, Denis Lindsay replied, "Trevor's swinging them in circles." Eight of the South Africans who won the series 3–1 had toured in Goddard's team in 1963–64.
