Australia overland

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 6 min read

Australia is a continent, not just a country, and its distances have a way of humbling even experienced travellers. An overland crossing — whether coast-to-coast or top-to-bottom — is one of the world's great slow travel journeys, combining two of the most iconic long-distance trains on earth with an honest encounter with the sheer scale of the outback. Here is how to plan it, what to expect, and what the distances actually mean once you are on the ground.

Understanding the distances

Before planning anything, it is worth sitting with the numbers. Sydney to Perth is around 4,000 km in a straight line — roughly the same as London to Tehran. Adelaide to Darwin is around 3,000 km. These are not distances you can cover in an afternoon, and the land in between is, for long stretches, some of the most sparsely inhabited terrain on earth. The Nullarbor Plain alone is 1,200 km of almost featureless, flat landscape with very few towns of any size. This is not a limitation — it is the point — but it means that "overland Australia" requires a different mental gear than, say, a European rail pass.

The Indian Pacific: Sydney to Perth

The Indian Pacific, operated by Great Southern Rail, is one of the world's longest passenger rail journeys: Sydney (Central Station) to Perth (East Perth Terminal) in approximately 65 hours — just under three days. Services run weekly (twice weekly in peak seasons) in each direction, passing through the Blue Mountains, Broken Hill, the desert of South Australia, the Nullarbor Plain and the wheat fields of Western Australia.

The journey can also be broken at Adelaide, where many travellers pause before continuing their overland route. Adelaide to Perth takes around 38 hours.

The Indian Pacific has three classes:

• Gold Service — private sleeper cabins (single or twin) with en-suite shower and toilet, and all meals included in a dedicated dining car. This is the standard way to do the journey in comfort.
• Platinum Service — larger, more luxurious cabins at a higher price point.
• Daynighter seats — a coach seat option that exists on some departures but makes the full 65-hour journey a considerably more challenging proposition.

Book well in advance, particularly for Gold Service cabins — the Indian Pacific sells out months ahead, especially in the cooler months (April to September) when the desert is at its most hospitable. Book directly through Great Southern Rail's website (journeybeyondrail.com.au).

The Ghan: Adelaide to Darwin

The Ghan runs between Adelaide (Adelaide Parklands Terminal) and Darwin (Darwin Railway Station), covering around 2,979 km in approximately 54 hours. Like the Indian Pacific, it runs weekly (twice weekly in peak season). The route passes through the red centre of Australia — Coober Pedy, Alice Springs, Katherine — in a landscape that shifts from arid scrubland to dramatic red rock country to the lush tropics of the Northern Territory.

The Ghan also offers optional off-train excursions at Alice Springs and Katherine Gorge that are well worth including; these add half a day or a full day to the journey. The Ghan's three service levels mirror those of the Indian Pacific (Gold, Platinum, Daynighter), and the same booking advice applies: plan well ahead.

Together, the Indian Pacific and The Ghan form the backbone of an overland crossing of Australia. A typical route might be: Sydney → Adelaide (Indian Pacific, ~26h) → Darwin (The Ghan, ~54h), or the reverse, with pauses in Adelaide and Alice Springs. Some travellers complete the full Sydney–Adelaide–Darwin combination in one overland arc; others take the Indian Pacific coast-to-coast and add The Ghan as a separate trip.

Greyhound Australia: filling the gaps

Greyhound Australia operates a nationwide coach network that reaches destinations and routes the trains do not, and for many overland travellers it fills the essential gaps. Greyhound is particularly useful for:

• The East Coast corridor (Sydney to Brisbane to Cairns) — one of the most popular backpacker routes in the country, with multiple daily departures and hop-on-hop-off passes available.
• Connections in the Northern Territory — Darwin to Kakadu, or Katherine to Darwin.
• Routes in Queensland's far north that have no rail link.

Greyhound Australia sells multi-day passes (the "Whimit Pass") that allow unlimited travel within a set period, which can be economical for travellers covering large distances over several weeks. Single fares are also available. Book through greyhound.com.au.

Coach travel in Australia over very long distances is slower than the trains and less comfortable, but for routes without a rail option, it is the practical choice. Night coaches are common on long segments, which saves on accommodation costs.

Practical planning: what a realistic overland route looks like

A thorough overland journey connecting Australia's major points of interest might look something like this:

1. Sydney — start here, or arrive by air from overseas.
2. Sydney to Adelaide — Indian Pacific (~26 hours).
3. Adelaide — spend a few days; explore the Barossa Valley or the Fleurieu Peninsula.
4. Adelaide to Darwin — The Ghan (~54 hours), with optional off-train excursions at Alice Springs and Katherine.
5. Darwin — explore Kakadu National Park (most easily done by hire car or tour from Darwin).
6. Darwin to Cairns — no direct train or quick route; Greyhound, a campervan, or fly.
7. Cairns to Sydney — Greyhound on the east coast, or a combination of Queensland Rail's Spirit of Queensland to Brisbane, then the XPT or NSW TrainLink south.

A trip of this scope takes at least three to four weeks to do justice; most travellers allow six to eight weeks or more. Be realistic about the pace — the Australian outback rewards lingering, and the train journeys themselves are events, not just transit.

Visas and entry

Most visitors to Australia need either a visa or an Electronic Travel Authority (ETA) before arrival. The ETA is available online for citizens of several countries including the UK, USA and EU member states. Check the Australian Department of Home Affairs website for current requirements — processing times and eligibility can change.

Frequently asked questions

How long does the Indian Pacific take?

The full Sydney to Perth journey takes approximately 65 hours — just under three days. The Adelaide to Perth segment takes around 38 hours. Services run once or twice a week depending on the season.

Can I stop off along the way on The Ghan or Indian Pacific?

Yes. Both trains allow passengers to book individual segments. You can break the Indian Pacific journey at Adelaide; The Ghan allows a stop at Alice Springs, where off-train excursions are available. You then continue on a later departure.

Is the train or Greyhound bus better for the east coast?

Both work. The east coast has Queensland Rail, NSW TrainLink, and several regional rail services, but Greyhound's hop-on-hop-off passes are popular with backpackers for flexibility. The trains are generally more comfortable over long distances; Greyhound reaches more small coastal towns.

How far in advance should I book the Indian Pacific or The Ghan?

As far ahead as possible — at least three to six months for peak season (April to September) if you want a sleeper cabin. Popular departures can sell out months in advance. Book directly at journeybeyondrail.com.au.
