Yes, a myki card is the primary way to pay for public transport in Melbourne, though its necessity depends on where you travel. In 2026, Melbourne still utilizes the Free Tram Zone in the Central Business District (CBD) and Docklands; if you only travel within this specific zone, you do not need a myki card at all. However, if your journey takes you outside the CBD, or if you use a train or bus, a myki is mandatory. You can choose between a physical plastic card (available at stations and 7-Eleven stores) or a Mobile myki on Android phones via Google Wallet. Interestingly, as of January 1, 2026, the Victorian government has introduced free public transport for everyone under age 18, but these younger travelers are still required to carry and "tap on" with a specialized Youth myki to validate their travel. For short-term tourists, the "myki Explorer" pack is often recommended as it comes pre-loaded with enough credit for a full day of travel to popular spots like St Kilda or the Melbourne Zoo.
