Playmander

The Playmander was a form of electoral malapportionment in the Australian state of South Australia, in place from 1936 to 1968. It consisted of rural districts enjoying a 2-to-1 advantage in the state parliament, even though they contained less than half of the population, as well as a change from multiple member to single member electorates, and the number of MPs in the lower house was reduced from 46 to 39.
