Overview

Jay Wilson Weatherill (born 3 April 1964) is an Australian politician who led the state government of South Australia as its 45th Premier from 21 October 2011 until 19 March 2018. A member of the Australian Labor Party, Weatherill became leader of the party’s state parliamentary team and steered Labor through two electoral campaigns, narrowly retaining government at the 2014 election before losing to the Liberals in 2018.

Early life and political rise

Before entering politics Weatherill had a background in law, policy and advocacy. He was first elected to the South Australian House of Assembly in the early 2000s, representing an Adelaide metropolitan electorate. During his time in parliament he served in a number of ministerial and shadow portfolios and was regarded as a pragmatic administrator with an emphasis on policy detail.

Premiership and priorities

As premier Weatherill presided over a period when South Australia became a focal point for national discussions about energy policy, renewable generation and grid security. His government promoted economic development, infrastructure investment and reform initiatives in education and health, often balancing competing fiscal and social priorities while responding to high-profile incidents and infrastructure challenges.

Legacy and notable features

Weatherill's tenure is frequently associated with the state’s increasing share of wind and solar power and with debates on how to ensure reliable electricity supply as the generation mix changed. He cultivated a reputation for detailed policy work and consensus-seeking, though his government also faced criticism on cost pressures and service delivery in some areas. The 2018 election ended his time as premier and returned the state to a Liberal government.
