Airstrips, charters at all towns, UHF Radio repeaters with 100 km range on various channels provide emergency contact with locals. Swimming pools and police stations at Oodnadatta and Marla
Some maps show Oodnadatta Track as route D95, which, under the extended Australian alphanumeric road numbering system, belongs to a D road, a category distinct from a C road. However, the D95 is not signposted, as the Department for Infrastructure and Transport has a policy of not marking unsealed roads.[6]
The track was named by Adam Plate of the Oodnadatta Progress Association in about 1980, to form a trilogy of unsealed tourist routes with the Birdsville and Strzelecki Tracks nearby. This road has no major intersections.[citation needed]
Route
The Oodnadatta Track heads southeast from Marla to Oodnadatta, and then roughly follows the former Central Australia Railway further southeast, until meeting the sealed Outback Highway at Marree. The road's surface has been well maintained in recent years.[when?]
In dry weather, the track is passable to most vehicles and caravans. A four-wheel drive (4x4) vehicle gives a more comfortable journey, and is essential for driving the track during and after rain. Since the track is unsealed, the Government of South Australia recommends that users check whether it is open before departure.
