11 November - Prime Minister John Gorton makes the most sweeping changes to the Federal Ministry since the Liberal-Country Party Coalition took office in 1949. Mr Gorton dropped three Ministers, recruited seven back-benchers to the Junior Ministry and promoted four new men to the Inner Cabinet. The biggest change was the dropping of Mr William McMahon from the Treasury. Mr McMahon, Treasurer since 1966, will be the new External Affairs Minister. The vital Treasury post will be filled by Mr Leslie Bury (former Minister for Labour and National Service). Another major Cabinet change was the promotion of the former Minister for Education and Science (Mr Malcolm Fraser) into the powerful Defence Ministry.
13 November - Former Minister for Air, Mr Dudley Erwin, expresses to journalists his belief that Prime Minister Gorton's young secretary, Miss Ainsley Gotto, was responsible for him being dropped from his ministerial position on 11 November, as well as asserting that Miss Gotto severely restricted access to the Prime Minister which he and other ministers had previously enjoyed. When asked what political manoeuvre had been used to get him out of office, he replied "it wiggles, it has a fine shape and its name is Ainsley Gotto".
