The South Australian Theatre Company (SATC) was established in 1965 under the artistic direction of John Tasker. The date of establishment as the state theatre company dates to the State Theatre Company of South Australia Act of 1972, an initiative of Don Dunstan. The name of the company was changed to its current name in 1980 as a reflection of this act. The director of the company in its inaugural year was George Ogilvie.
In 1974, the SATC became the resident theatre company of the newly built Adelaide Festival Centre, performing mostly in The Playhouse (later The Dunstan Playhouse, which is still the company's primary venue), and was the first state theatre company in Australia to hold its entire operations in one purpose-made building.
In 1977, Magpie Theatre was established as the youth arm of the company. It was lost in 1997, partially due to loss of funding after reconstruction of Arts SA.
Under the artistic direction of Jim Sharman, the company was renamed Lighthouse and became an ensemble theatre company with twelve actors: Robynne Bourne, Peter Cummins, Melissa Jaffer (replaced in 1983 by Jacqy Phillips), Alan John (also composer in residence), Gillian Jones, Melita Jurisic, Russell Kiefel, Stuart McCreery, Robert Menzies (replaced by Robert Grubb), Geoffrey Rush, Kerry Walker and John Wood .
