On his return to London in 1946, Lovelock rejoined the faculty at Trinity College and eventually became Dean of the Faculty of Music at the University of London in 1954. In 1956, he was appointed as the first Director of the Queensland Conservatorium of Music in Brisbane, Australia, but left in 1959 after disagreement over his teaching methods. However, he chose to stay on since, for the first time, he found that he had the time and freedom to compose seriously. Meanwhile, he supported himself as a free-lance teacher, adjudicator, and as chief music critic for "The Courier-Mail" in Brisbane.
