Political career
Scully was elected to the New South Wales Legislative Assembly as member for the safe Labor seat of Smithfield at the 1990 by-election. He is a member of the dominant right-wing faction of the New South Wales Labor Party. Scully held the ministerial portfolios of small business and regional development, state development, public works and services, roads and transport, housing and police. Scully was considered a possible candidate to replace Bob Carr as Premier of New South Wales, and announced his intention to run for the position after Carr announced his resignation in July 2005. But he withdrew from the contest on 29 July when it became clear that health minister Morris Iemma had majority support in the Labor Caucus. Although Scully publicly blamed the party machine for working against him, it was reported that some Labor MPs feared his record as transport minister during the Waterfall train disaster and other problems would have worked against the party at the next state election if he was leader. Iemma caved into pressure from powerbroker Eddie Obeid and decided to sack Scully as police minister on 25 October 2006 after a bad public image resulting from the delay of the release of the Cronulla riots report. Scully did not recontest Smithfield at the 2007 state election; and claimed he rejected an offer from Labor to contest a federal seat. In 2013 Scully testified that he was disappointed that Eddie Obeid, a powerbroker, had orchestrated Iemma becoming Premier instead of Scully. In 2017, Carl Scully released his autobiography titled “Setting the Record Straight”. In response to Scully's autobiography, “Setting the Record Straight”, journalist Emma Jones, wrote an article for The Australian, “”. In this article, Jones discussed how in Scully's autobiography, he made mention of a secret plan from World War II, which explained how best to blow upthe Sydney Harbour Bridge during an invasion from the North. Scully used the secret plan during his time in government, to assist in protecting the Sydney Harbour Bridge from terrorism after the September 11 terrorist attacks.
