Early life

Career
From a young age, Tonkin was a supporter of the
Liberal and Country League
The South Australian Liberal Party, officially known as the Liberal Party of Australia (South Australian Division), and often shortened to SA Liberals, is the South Australian Division of the Liberal Party of Australia. It was formed as the Lib ...

in Dunstan's seat of
Norwood before becoming the first member for the adjacent seat of
Bragg at the 1970 election.
Tonkin quickly gained a reputation as a progressive member of the LCL. He was an early supporter of the
Liberal Movement faction created by former premier
Steele Hall, although Tonkin remained with the LCL when the Liberal Movement split from it.
Tonkin gained statewide prominence in 1974, when he successfully introduced a private member's bill to outlaw sex discrimination, the first such law in Australia. A year later, this prominence led him to challenge
Bruce Eastick for the leadership of what by then had become the South Australia branch of the Liberal Party. Tonkin became leader after Eastick stood aside.
As leader, Tonkin worked toward healing the internal party wounds by coaxing the Liberal Movement back into the Liberal fold. Although the Liberals lost the
1977 election (Dunstan's government remained fairly popular with voters, and memories of the LCL split were still vivid), they easily won the
1979 election against Labor, briefly led by
Des Corcoran. At that election, the Liberals won 55 percent of the two-party vote on a swing of over eight percent. At the time, this was the largest two-party victory for any party since the end of the Playmander, exceeding Labor taking 54.5 percent in 1973. While this would have normally been enough for a strong majority government in the rest of Australia, the Liberals won only 13 seats in Adelaide. As a result, they only won 25 of 47 seats, just two more than needed to govern alone. Even so, it was the first time that the main non-Labor party in South Australia had won a majority of the two-party vote while also winning the most seats since its predecessor, the LCL, won 50.3 percent of the two-party vote in 1959.
Already governing on a knife-edge, Tonkin's majority became even slimmer in 1980 after a court decision threw out a Liberal victory in Dunstan's old seat Norwood, and Labor regained it in the ensuing by-election. As a result, Tonkin found himself with a bare majority of one seat.
Premier

Also serving as his own
state Treasurer, Tonkin combined fiscal conservatism with implementing socially progressive reforms. In the former, Tonkin made significant cuts to the public service, earning him the enmity of the unions, while an example of the latter was the passage of the land rights bill and the return to the
Pitjantjatjara people of 10 per cent of South Australia's area.

Graham Ingerson easily retained the seat for the Liberals at the
ensuing by-election.
Until the defeat of Steven Marshall in 2022, Tonkin was the only non-Labor Premier to have served for at least a full term since the main non-Labor party in South Australia adopted the Liberal banner.
After politics
Subsequently, Tonkin returned to ophthalmology and served in various capacities in different government and community organisations, including chairman of the board of the State Opera from 1985 to 1986 and vice-president of

Returning to Australia in 1992, Tonkin was made an Officer of the Order of Australia in 1993 and served as chairman of the
South Australian Film Corporation from 1994 to 1996. A stroke in 1996 permanently affected his speech and forced him into retirement.

Following his death, the Pitjantjatjara people paid tribute to Tonkin, stating that no Liberal politician had done as much for Aboriginal people. Others stated that he lost the 1982 election because he lacked the ruthlessness required of successful politicians.
