By-elections in SA

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.
