    Division of Bass

    Bass has existed since Tasmania was first divided into electorates in 1903, and has always consisted of the city of Launceston and some surrounding rural areas - it is one of the least changed of the federation seats. The seat has always been politically marginal and has frequently changed hands: it has had 17 members, the highest number of any seat. Only three of its 15 previous members have departed undefeated. In recent years it has become known as "the ejector seat."

    Bass has a relatively low income level, which should tip it towards Labor, but this is offset by its very low level of people born in non English speaking countries - it is one of Australia's most monocultural seats. The city of Launceston has some strong Labor areas, and George Town at the mouth of the Tamar is also traditionally a Labor town. These areas are offset by the middle-class suburbs of Launceston and most of the rural areas to the north and east.

    Lance Barnard won Bass in 1954 and was Deputy Prime Minister in the Whitlam government. His successor Kevin Newman was a minister in the Fraser government. Warwick Smith held the seat twice and was a minister in the Howard government, before being defeated by Michelle O'Byrne in 1998. In 2004 Mark Latham's anti-logging forestry policy cost Labor the seat. Michael Ferguson, who defeated O'Byrne, was an outspoken member, but his high profile was not enough to save him from the anti-government swing in 2007, when he was defeated by Jodie Campbell. Campbell did not enjoy being an MP and retired in 2010, when Geoff Lyons retained Bass for Labor. He was in turn defeated by Andrew Nikolic in the large swing against Labor that swept Tasmania in 2013.

    Nikolic had a distinguished career in the Australian Army and as a public servant in the Department of Defence, but he did not prove to be a particularly popular MP, and was easily defeated by Labor in 2016. Ross Hart, a Launceston lawyer, won the seat in 2016 but was defeated after one term.

    Bridget Archer, Liberal MP for Bass since 2019, worked at the Tasmanian Herbarium from 1995 to 1999, and was a self-employed farmer from 2008. She was a member of George Town Council 2009-19, and mayor of George Town. During her first term she became a noted backbench rebel, crossing the floor several times. This is a sure path to popularity in Tasmania, and in 2022 Archer defied the seat's recent history by becoming the first member for more than 20 years to be re-elected.
