Incumbent MP
Vincent Tarzia, since 2014.
Geography
Eastern Adelaide. Hartley covers the suburbs of Campbelltown, Hectorville, Magill, Paradise, Tranmere, and parts of Newton.
Redistribution
Hartley gained Dernancourt from Torrens and also gained Felixstow and Glynde from Dunstan, and lost Newton and part of Magill to Morialta.
History
Hartley was created for the 1977 election. The seat was Labor-held up until the early 1990s, and then Liberal-held until the 2006 election when it was won back by the ALP. It went back to the Liberal Party in 2014.
The seat was first won in 1977 by Des Corcoran, then Deputy Premier in the Labor government. Corcoran had held the seat of Millicent since 1962, when he replaced his father in the seat. Corcoran had served as deputy leader since 1968 and Deputy Premier since the Dunstan government won power in 1970.
Corcoran replaced Dunstan as Premier in 1979, and called a snap election which the Labor government lost. Corcoran retired from Hartley in 1982.
Terry Groom replaced Corcoran in 1982, and won re-election in 1985 and 1989. In 1991, an unfavourable redistribution made Hartley much less winnable for Labor, and Groom sought preselection elsewhere. After he failed to find a new seat, Groom resigned from the ALP and finished his term as an independent.
Joe Scalzi won Hartley for the Liberal Party in 1993. He was returned in 1997 after a large swing left him with a 0.7% margin. In 2002, he managed to increase his margin despite the Liberal Party losing power.
Grace Portolesi defeated Scalzi in 2006 with a 5.9% swing. She retained her seat in 2010 after a swing of 3.9% to the Liberal Party.
Portolesi lost her seat in 2014 to Liberal candidate Vincent Tarzia. Tarzia won a second term in 2018, seeing off a challenge by SA-Best leader and former senator Nick Xenophon.

Vincent Tarzia was hailed by the Liberals on election night as a giant slayer seeing off Nick Xenophon in Hartley. Tarzia certainly got some help with the Greens putting the Liberals ahead of Xenophon on their how to vote cards. Labor was also in no mood to give Xenophon a free lunch after Xenophon put out a open ticket on his how to vote cards which Labor in turn returned the favour. Xenophon failing to make the final two party preferred vote would have not been predicted by anyone before the election.
Tarzia has to be concerned by where the Xenophon vote will go (24.9%). Tarzia will need to lift his primary vote significantly to hold his seat as the last state election was different circumstances.
