Counting the votes for the House of Assembly

A majority system of voting and counting called preferential voting is used to elect members of the House of Assembly. Preferential voting was first introduced in South Australia in 1929. 

In order to win a seat in the House of Assembly, a candidate is required to obtain an absolute majority (more than 50%) of the total formal votes cast in an electoral district.

If, at the first count, no candidate has gained more than 50% of first preference (or number ‘1’) votes, the candidate with the least number of first preference votes is excluded. The excluded candidate’s ballot papers are then distributed to the remaining candidates according to the the second preference (or number ‘2’) votes on his/her ballot papers. The process of excluding the candidate with the least number of votes and distributing the next available preference continues until one candidate wins the seat by gaining more than 50% of the vote.

All House of Assembly election counts continue until only two candidates remain, regardless of whether any one candidate gains an absolute majority earlier in the count. This full distribution of preferences allows the Electoral Commission to calculate the two-candidate-preferred results.

If in the final count two candidates have an equal number of votes the matter is referred by the Electoral Commissioner to the Court of Disputed Returns where the Court may determine the validity of disputed ballot papers or, in the event of this action not resolving the dead-lock, order a new election. 

An example of how preferences work in the House of Assembly

Kate, Lyn, Tom and Steve stand for election.
They receive the following formal first preference votes:image1

There are a total of 20,000 formal votes.

To be elected a candidate needs an absolute majority (more than 50% - or more than half of the vote)

As none of the candidates has gained an absolute majority of the votes (more than 10,000) at this first count, the candidate with the least number of votes (Kate) is excluded and her ballot papers are transferred to the other candidates according to which candidate was allocated the number 2 (second preference).

Kate’s votes are transferred as follows:

After Kate’s ballot papers have been distributed, neither Lyn, Tom, nor Steve have yet gained an absolute majority. Lyn is now the candidate with the least number of votes so she is excluded and her ballot papers are distributed according to who was marked as the number ‘2’ (or the number ‘3’, if the ballot paper was previously transferred from Kate) preference.

Once the preferences on Lyn’s ballot papers have been distributed (4,000 are marked for Tom and 1,750 for Steve) the ballot papers for each of them are totalled.

Tom now has more than half of the total votes cast (an absolute majority) and is declared the elected candidate.

Counting the votes for the Legislative Council

A proportional representation system of voting called single transferable vote is used to elect members of the Legislative Council. This system has been used in South Australia since 1975.

In order to win a seat in the Legislative Council, a candidate is normally required to obtain a ‘quota’ of the formal votes. This quota - or minimum number of votes required to win a seat – ensures that winning candidates are elected with approximately equal numbers of votes. 

Counting the votes for the Legislative Council is both slower and more complicated than the count for the House of Assembly. On election night only first preferences are counted, leaving the major part of the count – i.e. the calculation of the quota, the distribution of surplus votes and the exclusion of candidates - to the days after the election.

Five steps are followed to count the votes for the Legislative Council:

Flowchart
A detailed explanation of the steps involved can be found below.

1. Counting the first preference votes

The first step in the process is to sort the ballot papers into first preferences for each group above the line and below the line, as well as first preferences for each ungrouped candidate. The first preference figures are then transmitted to the media and published on the ECSA website.

Once all declaration votes have come in from across the state and around the world – which cannot take place until the final postal votes have been received seven days after polling day - the total number of formal (or valid) votes can be calculated. This number is essential for the second step in the process, calculating the quota.

2. Calculating the quota

To be elected to the Legislative Council, candidates need to gain a minimum number – known as a quota - of the total formal votes. This quota is calculated by dividing the total number of formal ballot papers by one more than the number of Legislative Council members to be elected, and then adding one to the result (disregarding any remainder).

 Calc1

Example of calculating the quota using the 2014 State Election figures:
Calc3Therefore, the quota required to be elected at the 2014 State Election was 84,245.

3. Election of candidates who reach the quota

Candidates who receive a number of first preference (or number ‘1’) votes equal to or greater than the quota, are elected immediately. 

It is possible, although very unusual, for this to lead to all the vacant seats being filled, and therefore, the election being finalised. It is much more frequent however, for the Electoral Commission to need to move on to the next two steps in the counting process.

4. Distribution of surplus votes

If any elected candidates received more votes than the quota, their surplus votes are distributed to the remaining candidates according to the further preferences indicated on the ballot papers. 

Because it is not possible to determine which votes actually elected the candidate and which votes are surplus, all the elected candidate’s ballot papers are transferred at a reduced value called a ‘transfer value’. 

The transfer value is calculated as follows: 

Calc2

As surplus votes are distributed, other candidates may be elected. However, if at any point all the surplus votes from elected candidates have been distributed and there are still positions left unfilled, the Electoral Commission proceeds with the next step in the counting process.

5. Exclusion of unsuccessful candidates

Starting with the candidate who received the lowest number of votes, unelected candidates are excluded from the count. The excluded candidate’s ballot papers are distributed to the remaining candidates based on preferences. 

If any of the remaining candidates obtain a quota through this process of distribution, they are elected. 

Their surplus votes (if any) are distributed before any other candidates are excluded. This process of distributing surplus votes from elected candidates and excluding the candidate with the fewest votes is continued until all vacant Legislative Council seats are filled. 

Exhausted ballot papers

As a result of voting reforms before the 2018 State Election, the Legislative Council now has a partial preferential rather than fully preferential voting method. This inevitably leads to an increase in the number of votes that are ‘exhausted’ – i.e. ballot papers where no further preferences have been expressed. Once a vote has been ‘exhausted’, it must be set aside from the count.

Candidates elected without a quota

If, as a result of exhausted ballot papers, there are not enough votes left in the count to fill the remaining vacant seats, the candidate or candidates with the highest number of votes are elected regardless of whether they have reached the quota.

Disability Access and Inclusion Plan

 

Message from the Electoral Commissioner 

The Electoral Commission of South Australia (ECSA) is committed in making the 2018 State Election as inclusive and accessible as possible to all South Australians, including those living with a disability. 

Our Disability Access and Inclusion Plan sets out the objectives, outcomes and services that will guide ECSA’s approach to the Election. 

The Plan has been developed through consultation with a range of disability sector organisations, and focuses on delivering practical outcomes that will improve the accessibility of our voting and information services. 

The Plan has three main objectives: 

  • Deliver tailored and accessible information for electors with a disability. 
  • Deliver tailored and accessible voting services for electors with a disability. 
  • Improve the awareness of Electoral Commission SA staff regarding the needs of electors with a disability. 

Following 17 March 2018, ECSA will evaluate the success of the Plan in conjunction with representatives of South Australia’s disability sector as part of continuing commitment to improving the participation of people with disability in the democratic processes.
