Opal 60 minute transfer
With Opal, if you make several trips using the same mode of transport, and if your transfer occurs within 60 minutes from your last tap off, you only pay one fare based on the distance you travel. It applies to all services except the Manly Ferry service, where the transfer time is extended to 130 minutes from tap on.
The Opal 60 minute transfer doesn't apply at Sydney Airport Stations. If you tap off at the airport and tap on again within one hour, you'll be charged for two journeys, including two Station Access Fees. This gives you two paid journeys towards your Weekly Travel Reward.
