There is a caravan park (highly recommended) next to the Narromine Gliding Club which has limited units (with bathroom facilities and communal kitchen) but plenty of camping sites (with shared bathroom facilities and shared kitchen). The town of Narromine has several Motels if looking for more comfort:

Peppercorn Motel

Stockman Motor Inn

The competition organisers will provide meals every night and bar facilities will be available.

There is quite a variety of restaurants to eat at in Narromine.
