Geography Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned. History Established in the South Australian redistribution of 3 September 1984 and named after MP and diplomat Norman Makin, it was a marginal mortgage belt seat with a higher proportion of the population in the area paying off home loans. In the 2006 census, over 42 percent of the seat's electors had a home mortgage; ranking it 19th highest in Australia's 150 seats. Created ahead of the 1984 election as a notionally fairly safe Labor seat, Labor won marginally. For the first quarter-century of its existence, the seat was a "bellwether" seat held by the party of government, both often typical of mortgage belt seats. During this time, it was usually marginal, with neither party winning more than 54 percent of the two-party vote. Later years Labor's Tony Zappia won the seat at the 2007 election with a fairly safe 57.7 percent two-party vote against Liberal candidate Bob Day from an 8.6 percent two-party swing as Labor won government, the largest two-party vote and swing of any party in Makin's history at the time. Zappia won enough primary votes to take the seat on the first count, the first time a candidate won a majority of the primary vote in Makin. At the 2010 election, Zappia technically made it a safe Labor seat with a 62.2 percent two-party vote, again the strongest result for any party in Makin's history.
