The electoral district of Hartley is named after John Hartley, who helped create South Australia's public education system.
The 15.5 square kilometre electorate contains the suburbs of Auldana, Campbelltown, Felixstow, Glynde, Hectorville, Kensington Gardens, Magill, Rosslyn Park and Tranmere, as well as parts of Paradise and Payneham.
Hartley is a hard working, multicultural electorate. A significant proportion of people are from migrant families, with 48 per cent having both parents born overseas and 35 per cent speak two or more languages. There is barely a weekend that does not feature a fair, a fete, a Festa, a festival or a fundraiser.
Vincent Tarzia has lived in the area for many years, and was elected to the South Australian Parliament in 2014.
