Death of premier (Cahill): Beginning of Heffron's period in office; 'On 22 October 1959 Cahill died. Heffron was immediately commissioned as Premier subject to being confirmed as leader of the Labor Party. On 28 October caucus elected him leader unopposed and filled the vacancy in the ministry', Hughes and Graham, p. 80, (see 'Sources', below).
Change of party leader (Heffron): 'On 28 April Heffron retired. On 29 April caucus elected Renshaw as leader and filled the vacancy in cabinet', Hughes and Graham, p. 84, (see 'Sources', below). Williams argues that disputes within the Australian Labor Party over an initiative by Heffron to introduce state aid to church schools undermined his public standing and was a major factor in the timing of his resignation as premier; Williams, pp. 326-328 (see 'References', below).
