Holt's initial cabinet was virtually unchanged from that of his predecessor. John Gorton and Les Bury were promoted to replace Menzies and Paltridge, but there were no other changes in composition. There were also no major changes in portfolio, outside of McMahon's promotion to Treasurer in place of Holt. A notable addition to the outer ministry was Senator Annabelle Rankin as Minister for Housing – the first woman to hold a ministerial portfolio. A minor reshuffle occurred after the 1966 election, with Doug Anthony and Ian Sinclair added to cabinet and Charles Barnes demoted to the outer ministry. The only new government department created during Holt's tenure was the Department of Education and Science, established in December 1966, which was the first federal department specific to either of those areas.
