Originally named "Beautiful Valley",[8] Wilmington is a farming community, known for sheep, wheat and barley, but more recently the temperature conditions and rainfall have contributed to the increasing popularity of the planting of olive groves.
The town has a post office, hotel, two caravan parks, take-away shop, two service stations, primary school, kindergarten, museum and op shop.
The town and surrounding areas formerly had their own municipality, the District Council of Wilmington, which merged into the current District Council of Mount Remarkable in 1980.[10]
Transport
Wilmington was the northern terminus of the Wilmington railway line from 1915 when the line was built until it closed in 1990.
Wilmington is on the Horrocks Highway at the junction where Main North Road turns west to pass through Horrocks Pass, and Horrocks Highway continues north to Quorn, South Australia. South of Wilmington, the same road carries both names to Gawler on the northern outskirts of Adelaide.
Terka
A town was surveyed in 1924 adjacent to the Terka railway siding six kilometres south of Wilmington, which was named from a nearby homestead. The town was "declared ceased to exist" in 1983 and is now considered to be part of the area of Wilmington.[11]
