Gidgealpa, SA 5731, is a remote locality in the northeastern part of South Australia, situated within the Outback region. Known for its arid landscape and sparse population, Gidgealpa is primarily significant for its role in Australia's energy sector, as it is home to the Gidgealpa gas field, part of the Cooper Basin, which is one of the country's major sources of natural gas. The area is characterized by its vast, flat terrain, red earth, and limited infrastructure, with the nearest major town being Innamincka, approximately 100 kilometers away. Gidgealpa serves as a hub for mining and energy operations, attracting workers and contractors rather than permanent residents. Its isolation and harsh climate make it a quintessential representation of Australia's rugged Outback.
