Which cards Sydney readers accept
Transport for NSW accepts American Express, Mastercard and Visa credit and debit cards for contactless travel, and the same cards loaded into Apple Pay, Google Wallet or Samsung Pay on a phone or watch. The contactless payments page names those three networks and no others. Contactless works across Sydney, the Blue Mountains, Central Coast, the Hunter and the Illawarra.
Cards outside that list are refused at the gate, and so are some cards inside it. The Opal reader shows "Card Not Valid" with a number, and the contactless payments FAQ explains what each one means.
- Error 91 means the card is not Amex, Mastercard or Visa, or is not contactless-enabled. Cards on other networks fall here.
- Error 89 means you are using a prepaid card, or a credit or debit card that is not accepted on the Opal network. Travel money cards and many prepaid travel products fail this way.
- Error 87 means the card is old and lacks the features needed for contactless transport payments.
- Error 88 means insufficient funds, a card reported lost or stolen, or unsettled fares from earlier travel that must be paid before that card works again.
A declined card leaves you three fallbacks: an Opal card, an Opal single trip ticket, or a different contactless card. Test your card at a quiet station gate early, not when you need to be somewhere.
When an Opal card still wins
An Opal card is the better choice in a short list of situations. You need one for a child aged 4 to 15, because Child/Youth fares cannot be paid with a credit or debit card. You need one if your card is prepaid or on an unsupported network. Some concession types, including seniors cards issued outside NSW and the ACT, must also use a physical card.
This compares the three ways an adult can pay on the same journey.
| Option | Who it suits | What you give up |
|---|---|---|
| Own contactless card or phone | Most adult visitors | Possible foreign transaction fee from your bank |
| Adult Opal card | Prepaid or unsupported cards, budget control | A trip to a retailer, and leftover balance at the end |
| Opal single trip ticket | A one-off backup when nothing else works | Higher price, no caps, no off-peak discount |
Transport for NSW says on its single tickets page that tapping on with an Opal or contactless card is cheaper than a single trip ticket, and that single tickets earn no Opal benefits.
Tap on and tap off, same card
You must tap on and tap off with the same physical card or device for every trip, or the fare cannot be calculated. Transport for NSW gives the exact failure mode: tap on with the card in your iPhone and tap off with your Apple Watch, and the system sees two separate cards, so you can be charged two default fares. A default fare is the maximum possible fare for that trip.
The same rule bites on the way in. Two contactless cards presented together confuse the reader, which Transport for NSW calls card clash.
Pick one payment method on your first day in Sydney and use only that for the whole visit. Switching cards mid-journey also costs you the transfer discount, because the system no longer sees one journey.
Caps, transfers and off-peak
Contactless payments receive the same Opal benefits as an Opal card, including the daily, weekly and Friday/weekend caps, the transfer discount and the off-peak discount. The Opal benefits page lists them together for both payment methods, so there is no fare penalty for tapping your own card.
Peak on metro, train, bus and light rail runs 6.30am to 10am and 3pm to 7pm, with Intercity trains starting their morning peak at 6am. Everything outside those windows, plus all of Friday and the weekend, gets the 30% discount. A single adult metro or train trip of 0 to 10km was AUD 4.33 in peak and AUD 3.03 off-peak on the adult fares page; a bus or light rail trip of 0 to 3km was AUD 3.30 and AUD 2.31, and a ferry trip of 0 to 9km was AUD 7.35.
Two more rules quietly reduce what you pay. Several trips on the same mode within 60 minutes of your last tap off count as one journey at one distance-based fare, extended to 130 minutes from tap on for the Manly ferry. Transfers between Sydney Metro, Sydney Trains and NSW TrainLink Intercity services count as one journey with a single fare, and you do not tap off in between.
The Sydney Airport station access fee sits outside all of this. It is added to your fare at the airport train stations, it is not included in the daily or weekly travel caps, and it has its own separate weekly cap. Our Sydney Airport transfer guidance covers how much it is and how to avoid it.
Children, concessions and groups
Children aged 4 to 15 need a Child/Youth Opal card, because the contactless FAQ states that Child/Youth, School Opal and Free Travel Opal fare types cannot tap with a credit or debit card. Children aged three and under travel free on all public transport in the Opal network, with no card and no ticket.
Adults with a concession entitlement have a choice. Most Concession and Gold Senior/Pensioner holders can open a Transport Connect account, link the entitlement to a contactless card, and get the discounted fare when they tap; link it before you travel, or you are charged the Adult fare. Seniors cards issued outside NSW and the ACT, asylum seekers, Department of Veterans Affairs holders and Free Travel Opal holders must use a physical Opal card.
Most overseas visitors will not qualify for an Australian concession, so budget Adult fares for everyone 16 and over.
What your own bank adds
Your card issuer, not Transport for NSW, decides whether an overseas-issued card attracts a fee. The visitor payment page states that a card issued overseas may attract a foreign transaction fee from your issuer, and that this is one charge per day rather than one per trip, because your day's fares are batched.
An Opal card moves the cost rather than removing it. You load Australian dollars once, so conversion happens once, but a leftover balance is hard to recover: a refund needs an Australian bank account and an Australian address. Load conservatively for a short stay.
Buying and topping up Opal
Adult and Child/Youth Opal cards are sold over the counter at Opal retailers, which include convenience stores and newsagents, and are also available on the Opal website, at selected Transport Customer Service Centres and at selected Service NSW locations. Concession and Gold Senior/Pensioner cards must be ordered online, with 7 to 10 days allowed for postage, so they are not a practical option for a short visit.
The card itself is free, but you have to add value before you travel, and some cards are issued with a zero balance. The top up page sets the minimum top up at AUD 10 for an Adult Opal card and AUD 5 for Concession, Child/Youth and Gold Senior/Pensioner cards.
- Opal retailers and top-up machines put the money on the card immediately, which is what you want on arrival day.
- Online and the Opal Travel app take 15 to 60 minutes to process, so they are for planning ahead, not for the platform.
- Retailer conditions vary. Some retailers set minimum transaction values or charge a service fee.
- Activate within 60 days. An online top up must be activated by tapping on at an Opal reader within 60 days.
If you top up online for a trip you are about to take, you will probably be at the gate before the money arrives. Use a machine or a retailer instead.
Before your first tap in Sydney
Settle the payment question before you reach a gate, not while people queue behind you.
Fares, caps and accepted networks change. Confirm current figures on the Transport for NSW fares pages before you budget a longer stay, and use the Trip Planner to price a specific journey.
