In 1977, the polling places were: Greenacres, Hillcrest, Klemzig, Manningham, Marden, Paradise West, Vale Park, Windsor Gardens and Windsor Grove.
Gilles was the Dunstan Labor government's most and only marginal seat following the 1973 election, and the Dunstan Labor government's most marginal seat following the 1975 election. Gilles was abolished in a boundary redistribution at the 1993 election. The re-created seat of Torrens absorbed much of the seat, remaining a marginal Liberal seat.
