Having toured Australia in 1929 for J. & N. Tait, Williams was urged by the Australian Broadcasting Commission to return to his homeland for the Thomas Beecham tour of 1940. He proceeded to become an important touring soloist throughout the duration of World War II and also taught at the New South Wales State Conservatorium of Music in Sydney. In September 1946, he took part in the concert marking the inauguration of the BBC Third Programme, singing in the "Serenade to Music", with Isobel Baillie, Astra Desmond, Bradbridge White and the BBC Symphony Orchestra and chorus conducted by Sir Adrian Boult.
