Though controversial, it was the longest term of any elected government leader in Australian history. His tenure as premier was marked by a period of population and economic growth unmatched by any other Australian state. He was known for his parochial style in pushing South Australia's interests, and was known for his ability to secure a disproportionate share of federal funding for the state as well as his shameless haranguing of federal leaders. His string of election wins was enabled by a system of malapportionment and gerrymander that bore his name, the 'Playmander'.
