Morialta is a word derived from the Kaurna aboriginal word 'mariyatala', 'mari' meaning east and 'yertala' meaning flowing water. The land used by the Morialta Conservation Park was traditionally occupied by the Kaurna people. Morialta was the new name adopted in 2002 for the electoral district of Coles, which was first created at the 1970 election and represented over the years by several distinguished MPs, including former Dunstan Labor government Attorney General Len King, and former Premier Des Corcoran.

Morialta was won at the 2002 election by Liberal minister Joan Hall, the last member for Coles, on a margin of 4.1 percent, suffering a -2.4 percent swing. At the 2006 election, Hall was thought likely to again hold the seat with a reduced margin, but was defeated by Labor candidate Lindsay Simmons amidst Labor's statewide landslide, receiving a 12 percent two-party preferred swing to finish with a 7.9 percent margin. However, at the 2010 election the electorate there was a swing of 11.1 percent back to the Liberals, with candidate John Gardner defeating Simmons by a margin of 4.1 percent.
