Train travel in Australia is a tale of two extremes: highly affordable urban commuting versus some of the most expensive luxury rail journeys in the world. For daily travel within cities like Sydney (Opal) or Melbourne (myki), the cost is very reasonable and capped at daily maximums. However, Australia is famous for its "Great Southern Railways"—The Ghan and the Indian Pacific. In 2026, these transcontinental journeys are positioned as premium "bucket list" experiences rather than simple transport. A gold-service ticket for a 3-night journey from Sydney to Perth can easily cost $3,000 to $4,500 AUD per person. These prices include all-inclusive fine dining, private cabins, and off-train excursions. While there are regional trains like the V/Line in Victoria or NSW TrainLink that are much cheaper for shorter distances, crossing the vast Australian outback by rail is a significant investment. For budget travelers, the "Discovery Pass" for regional rail is a common peer-to-peer recommendation to save money while still seeing the country's diverse landscapes.
