Periodic elections for the Tasmanian Legislative Council were held on 1 May 2021. The three seats that were up for election are Derwent, Mersey and Windermere.[1] They were last contested in 2015.[2] Only two of the three seats were actually contested, as the incumbent candidate for Mersey, Mike Gaffney, was returned unopposed.[3]
The periodic elections coincided with the snap general election for the House of Assembly.[4]
The seat of Derwent has been held by Labor member Craig Farrell since 2011, when he won the seat in a by-election triggered by the resignation of Michael Aird. Farrell has been President of the Tasmanian Legislative Council since May 2019.[5]
The seat of Mersey was held by the independent Mike Gaffney, first elected in 2009. Gaffney was the only candidate to nominate, and was declared elected unopposed on 1 April 2021.[6] [3]
The seat of Windermere was held by the independent Ivan Dean from 2003. Dean retired at this election.[7] The seat was won by Liberal candidate Nick Duigan.[8]
