Second mandate Prior to the electoral reforms for the 2026 election, the seats in the state parliament were allocated proportionately amongst parties which received more than 5% of valid votes across the state. The seats that were won proportionally for parties that did not win as many first mandates as seats they were entitled to, were allocated to their candidates which received the highest proportion of the vote in their respective constituencies. This meant that following some elections, a constituency would have one or more members elected under a second mandate.
Prior to 2011, these second mandates were allocated to the party candidates who got the greatest number of votes, whilst from 2011-2021, these were allocated according to percentage share of the vote.
Prior to 2016, this constituency did not elect any members on a second mandate.
