On the Indian Pacific—one of Australia’s most iconic long-distance rail journeys—the Gold Twin is the standard class of sleeper cabin. It is a private, air-conditioned compartment that features a comfortable three-seater lounge by day, which the staff converts into upper and lower berths (bunk beds) by night. A key feature of the Gold Twin is its private en-suite bathroom, which includes a compact shower, toilet, and washbasin. Passengers in Gold Twin also enjoy "all-inclusive" service, meaning all high-quality meals in the Queen Adelaide Restaurant, as well as a selection of alcoholic and non-alcoholic beverages in the Outback Explorer Lounge and during off-train excursions, are included in the fare.
