Raised to air commodore in 1946, McLachlan served with the British Commonwealth Air Group in Japan until 1948. After leading North-Eastern Area Command in 1951–53, he attended the Imperial Defence College, London. Promoted to air vice marshal, he returned to Australia in 1957 as Air Officer Commanding Training Command, carrying out major reviews on the RAAF's educational and command systems. He was Deputy Chief of the Air Staff in 1959–61, and then Head of the Australian Joint Services Staff in Washington, DC, until 1963. McLachlan's final post before retiring in 1968 was as Air Member for Supply and Equipment. He was a consultant to Northrop after leaving the RAAF.
