How to Set Up Auto Top-Up on Your Opal Card

What Auto Top-Up Does

Auto top-up automatically adds credit to your registered Opal card when your balance falls below a threshold you choose. It prevents the frustration of tapping on only to see "insufficient balance" on the reader, and it removes the need to visit a newsagent or top-up machine before every trip. Transport for NSW charges the amount you select to the credit or debit card linked to your Opal account, and the credit usually appears on your card within 15 to 60 minutes.

Step 1: Register Your Opal Card Online

Auto top-up is only available for registered cards. If you have not yet registered, go to the Opal website and click "Register." You will need your Opal card number, which is printed on the back of the card, plus a valid email address and a password for your account.

Registration takes roughly two minutes. Once your account is active, log in and select your card from the dashboard. Unregistered cards and contactless bank cards cannot use auto top-up because they have no stored balance to top up.

Step 2: Add a Payment Method to Your Opal Account

Before you can enable auto top-up, you must link a credit or debit card to your Opal account. Log in, select "Payment" from the profile dropdown in the top right corner, and follow the prompts to enter your card details. Transport for NSW uses tokenised payment processing, so your full card number is not stored on Opal servers.

Make sure the card you link has sufficient available credit or funds. Auto top-up triggers when your balance drops below your chosen threshold, not on a fixed schedule, so the payment must succeed at whatever time the trigger fires.

Step 3: Set Your Auto Top-Up Threshold and Amount

In your Opal account dashboard, select "Auto top up." You will see two settings to configure:

• Trigger balance: The point at which auto top-up activates. For Adult Opal cards, the minimum trigger balance is $10. For Concession, Child/Youth, and Gold Senior/Pensioner cards, the minimum is $5.
• Top-up amount: The amount added when the trigger fires. You can choose any amount that suits your commute pattern. A $20 top-up covers roughly four to five inner-city trips for an adult traveller.

Select "Turn on auto top-up" to activate. You can change or disable the setting at any time through the same menu.

Step 4: Verify It Is Working

After enabling auto top-up, do not wait for your balance to run low to test it. Instead, log in to the Opal Travel app or the Opal website and confirm that the auto top-up icon appears next to your card number. You can also make a small manual top-up of $1 via the app and then check that your payment method is listed as active.

Transport for NSW sends an email confirmation when an auto top-up transaction processes. If you do not receive this email after your first automatic top-up, check your spam folder and then verify that your payment details are still current in the "Payment" tab of your account.

Step 5: Managing Multiple Cards and Devices

If you use both a physical Opal card and a digital Opal card in your mobile wallet, treat them as separate cards. Auto top-up applies to the specific card you registered and enabled it for. A digital Opal card in Apple Wallet or Google Wallet has its own card number and must be registered separately if you want auto top-up on it.

If you share an Opal account with a partner or family member, each person should have their own registered card with their own payment method. Mixing payment methods on shared cards complicates trip history and can delay refunds if a trip was charged in error.

Troubleshooting

Auto top-up sometimes fails to trigger if the Opal system is processing a high volume of transactions during peak travel periods. Online top-ups can take up to 60 minutes to process, so if you tap on immediately after a top-up and see an insufficient balance message, wait a few minutes and tap again at the same reader. If the problem persists, call the Opal contact centre on 13 67 52 or visit a Service NSW centre with your card and identification.
