Yes, you can use your phone as an Opal card in Sydney. As of 2026, Transport for NSW has fully integrated contactless payments across all modes of public transport, including trains, buses, ferries, and light rail. You can simply tap your smartphone using Apple Pay, Google Pay, or Samsung Pay (linked to a valid credit or debit card) on the Opal readers at station gates or on buses. The system automatically calculates the correct fare, including the same daily and weekly "fare caps" that physical Opal card users receive. Additionally, the Opal Next Gen program allows for digital Opal cards to be stored directly in your phone's digital wallet, providing a more seamless experience for managing concessions or student balances without needing a physical piece of plastic.
