- - the Rundle government, backed by Labor, reduced the size of the House of Assembly and called an early election. There was a change of government with the Labor Opposition wining a majority.
- - the Bartlett Labor government lost its majority at an election that split the Assembly 10 Labor, 10 Liberal, five Greens. After feigning to resign, Premier Bartlett formed a coalition government with the Greens.

- 30 members from 1909 to 1956 with six members elected per division.
- 35 members from 1959 to 1996 with seven members elected per division.
- 25 members between 1998 and 2021 after a controversial reduction to five members per division.

- Unlike the Senate, there is no 'above-the-line' group voting square allowing electors to vote for all a group's candidates in the order listed on the ballot paper.
- Without group voting squares, preferences must be completed for candidates. Voters must mark as many preferences as there are vacancies to fill. In 2024 there must be seven preferences completed, up from five in in 2021.
- Voters are free to mark preferences for candidates in one column or many columns and do so in whatever order that voters choose. As long as a minimum seven preferences are completed.
- Parties and groups cannot determine the order in which their candidates are listed in ballot paper groups.
- The order candidates are listed in each group is shuffled by a process known as 'Robson rotation'. With seven candidates, each candidate will appear top of the group on one-in-seven ballot papers. The same one-in-seven rule applies to all positions in a group. The number of rotations is smaller with fewer than seven candidates. In each division there will be 14 different versions of the ballot paper.
- The shuffling of order means there is no positional advantage for candidates in a column. Any top of the list advantage from 'donkey' voting is randomised, as are preferences from so called 'linear' or down the ticket votes.
- Parties and groups elect a number of members in rough proportion to their vote share. Which of each group's candidates are elected will depend on their personal popularity and campaigning. The same comment applies to the ability of candidates to attract second or further preferences.
- The distribution of how-to-vote material is banned outside voting centres and on polling day. Publishing any how-to-vote recommendation is complicated by all candidates listed having to agree to the recommendation.
- three Labor victories with three seat majorities - 1998, 2002 and 2006,

- in reaction to the previous term of government, one Liberal victory in 2014 with a landslide 5-seat majority,
- two Liberal governments elected in 2018 and 2021 with one-seat majorities.
