The
Liberal and Country League (
LCL) was the major
conservative party in
South Australia from 1932 to 1974. In its 42-year existence, it spent 34 years in government, mainly due to an electoral
malapportionment scheme known as the
Playmander, introduced by the LCL government in 1936, which saw a change from
multi-member to
single-member seats in the
lower house, a reduction of seats from 46 to 39, and two thirds of seats to be located in
rural areas ("the country"). This arrangement was retained even as
Adelaide, the state capital, grew to two-thirds of the state's population. The most populous Adelaide-area seats had as much as 5-10 times the number of voters than the least populous rural seats - at the
1968 election the rural seat of
Frome had 4,500 formal votes, while the metropolitan seat of
Enfield had 42,000 formal votes. Additionally, with a decisive advantage to the LCL, swing voters may have been more likely to vote for the expected status quo LCL government.
