What AI says about Opal

Opal is the ticketing system used on public transport across Sydney, the Blue Mountains, Central Coast, the Hunter, and the Illawarra. You travel by tapping on and off with an Opal card or with a contactless credit or debit card for most fares, and concession fares require a Transport Connect account linked to your entitlement. You can obtain an Opal card online or in person, top it up online or automatically, and manage your card (balance, lost or stolen) as well as explore fares, concessions, and payment options.
