Halfway along one of Australia's loneliest four-wheel-drive tracks, a small roadhouse doubles as a fuel stop, a memorial to a Native Title fight and, now, home to what may be the world's most remote camera obscura.

Ilkurlka sits on the Anne Beadell Highway, an unsealed 1,380km crossing of the Great Victoria Desert. There is literally nowhere else to buy fuel between Laverton in Western Australia and Coober Pedy in South Australia — it's 550km east of the former, 770km west of the latter. But the roadhouse's story goes well beyond diesel.

The name comes from a nearby sacred rock hole, a kapi piti that anchors the Kalaya Tjukurpa (Emu Dreaming) and several intersecting songlines. Spinifex people explain a smooth patch on the rock's surface as the mark left by an emu that gorged on wild tobacco before drinking there. After the Cundeelee Mission closed in 1985, Elders wanted to resettle at Ilkurlka, but the terrain made it impractical — so they founded the community of Tjuntjuntjara 130km south instead.

Art became the tool for reclaiming the land. From 1997, the Spinifex Arts Project sent Elders on 'bush trips' to paint birthplaces and Creation stories, including winter camps near the Ilkurlka rock hole where the late artist Roy Underwood, the site's main custodian, worked. Those canvases, documenting custodianship in classic Western Desert style, were included in the preamble to a successful Native Title claim covering 55,000sq.km of desert, finalised in 2000. The Spinifex people's raw, intense style has since earned national and international attention.

In 2004 the community built the roadhouse, manager's house and camping facilities at Ilkurlka to serve locals and Anne Beadell travellers. The artistic streak continued: an old caravan that once served as a School of the Air classroom — towed over 110 sandhills decades ago — was converted into a camera obscura. Step inside and the desert projects itself upside-down across the white walls: blue sky and drifting clouds on the floor, swaying gum trees and red dunes wrapping around you, accompanied by a recorded soundscape of birds, breeze and brushstroke. The work, Nganampa Ngura Talingka Ngurulpa (Our Home Between the Dunes), was created with Anangu artists from the Milpa Project and Fremantle photographer Duncan Wright.

For anyone tackling the Anne Beadell, Ilkurlka is more than a mandatory fuel stop — it's a chance to understand why this stretch of desert matters to the people who fought to get it back. Milpa Project artist Shonna Jamieson puts it simply: camping in the dunes there is quiet, and the stars are spectacular. Just bring everything else you need with you.
