On OzBargain, a commuter tapped on with the wrong debit card, one with $2 in it. Days later only $1 had come out, so they asked if they'd found a hack. Replies were quick. One said "your card gets banned on failed payment". Another, paying by Visa debit, said a $7.08 charge "finally" appeared three days after a Sunday Metro return trip.
It's not a hack. The fare just turns up later, and if it can't be collected on the day, it comes back as an Opal overdue fare.
The quick answer
- What it is: "TfNSW Opal OverdueFare" is a contactless fare that couldn't be processed on the day you travelled, for example because there wasn't enough money in the account or your bank had a temporary payment problem. It's your travel cost, charged late.
- Why your card stops working: under the Opal Terms of Use you can't travel with that card or device until unpaid fares are paid in full. Readers show Card Not Valid, error 88.
- How to clear it: put money back in the account, then settle the outstanding amount through TfNSW's contactless login. TfNSW will also try to collect it the next time you tap.
- Need to travel now? Use an Opal card, an Opal single trip ticket or a different contactless card.
- Wrong amount? Only a faulty reader, an outage or a service disruption can be reimbursed. Contactless claims cover trips from the last 80 days.
What "TfNSW Opal OverdueFare" means
TfNSW explains its statement descriptions in the How fares are processed section of its contactless payments FAQ . Normal travel shows as "TfNSW Opal Fare". An overdue fare is the one you see "when your full fare could not be processed on the day of travel".
The timing is why it surprises people. When you tap on, TfNSW holds $1 as a pending pre-authorisation. During the day your fares add up, and the total replaces that $1 when it's processed at 4am the day after travel. If that 4am payment is declined, TfNSW keeps trying (see below), and whatever is collected late shows up as an overdue fare, so it can land days after the trip.
Every Opal line on your bank statement, decoded
The FAQ lists four descriptions:
- Transport NSW Login: the temporary $1 pre-authorisation. It's a hold, not a charge.
- TfNSW Opal Fare: your normal fares for the day, processed at 4am the next morning.
- TfNSW Opal OverdueFare: fares that couldn't be processed on the day of travel and were collected later.
- TfNSW Opal DefaultFare: TfNSW's only explanation is "when you fail a fare compliance check".
TfNSW also says charges or fare adjustments can show up to seven business days later, for example when you hit a daily or weekly travel cap. If a charge still looks wrong after seven business days, the FAQ tells you to contact your card issuer.
Why the Opal reader now says "Card Not Valid" (error 88)
The other place an unpaid fare shows up is at the gate. The FAQ's list of reader error codes says error 88 means "the card has insufficient funds, or has been reported lost or stolen", and that "outstanding fares for any prior travel also need to be settled before the same card or device can be used again to travel".
The Opal Terms of Use set this out in clauses 2.12 and 2.13. If your bank declines the payment, these "Unpaid Fares" can be retried "on a number of additional occasions until we receive the full payment". TfNSW will "also attempt to collect any Unpaid Fares the next time you validate your Device". Until it's paid in full, "you will not be permitted to travel using the Device".
The block applies to that card or device. TfNSW's own advice is that you "can still use an Opal card, Opal single trip ticket or a different contactless card to travel".
How to clear an Opal overdue fare
- Fix the cause. Make sure the account linked to the card has money in it (clause 2.21 of the Terms of Use makes that your job). If your bank says the card was reported lost or stolen, that's for the bank to sort out. The FAQ says to contact your card issuer about any of the error codes.
- Settle what you owe. The error 88 entry links to TfNSW's contactless login page , with the words "You can settle outstanding payments here". That's the official place to pay it off.
- Check the amount. The overdue amount should match your fares for the day it covers. If you have a Transport Connect account, your trips are listed there. Without one, TfNSW shows only your last 10 contactless trips.
Is the overdue amount itself wrong?
An overdue fare doesn't get its own refund route. It's just your ordinary fares collected late. But if a trip inside it was charged incorrectly, the usual reimbursement rules apply. TfNSW's contactless reimbursements page accepts three reasons: an Opal reader problem, being unable to tap off because of an evacuation or a power or equipment outage, and a default fare caused by a service disruption. You request it through Transport Connect's "Fare not right" or, without an account, from the self-service last 10 trips page.
The same page lists trips you can't get back. That includes anyone who "tapped on or off incorrectly", so a forgotten tap off stays charged. So does tapping off with a different card or device from the one you tapped on with.
A worked example of the deadline: say you travel on Monday 5 October and the 4am payment the next morning is declined. You top up and the overdue fare is collected the following week. Later you notice one trip that day carries a default fare because a reader at the gate was dead. The 80-day limit counts from the trip, not from when the money left your account, so you have until about 24 December to ask.
What about Opal cards?
An overdue fare is a contactless thing. An Opal card spends its own stored balance. Under clause 1.68 of the Terms of Use, if that balance can't cover a fare or goes negative, you top up before your next trip, and the top-up pays off the negative balance first. Opal card fare adjustments (same three reasons) go through your Opal account, or the enquiries form for unregistered cards, as Complaint - Opal fares within 90 days, as covered in our Opal fare adjustment guide .
Check an Opal card's history for default fares
Overdue fares are a contactless problem, but default fares hit Opal cards as well, and you won't spot them from your balance alone. Download your history (our guide to downloading your Opal, go card or myki history shows where), then drop it into FareClaim . It flags trips with no tap off, missed transfers and duplicate charges, with the date, time and stop you'd need for a claim.
FareClaim is free and run by volunteers. Your file is checked in your browser and never uploaded. There are no ads, we take no cut, and we're not affiliated with TfNSW. FareClaim doesn't lodge claims: you send them yourself. It reads Opal card exports (plus go card and myki), but it can't read contactless history yet.

FAQ
Is an Opal overdue fare a fine or a penalty?
No. TfNSW describes it as your full fare that "could not be processed on the day of travel". We couldn't find any surcharge for overdue fares in either the FAQ or the Terms of Use.
Why did the overdue fare come out days after my trip?
Fares are processed at 4am the day after travel. If that payment fails, the Terms of Use let TfNSW retry it several times and also collect it the next time you tap. TfNSW says some charges and adjustments appear up to seven business days later.
Can I keep using my bank card before I've paid?
No. Clause 2.13 says you can't travel with that card or device until unpaid fares are settled in full. The reader will reject it with error 88.
Can I get an overdue fare refunded?
Only the part that was charged wrongly, and only for the three reasons TfNSW accepts (reader fault, evacuation or outage, service disruption), within 80 days of the trip. A forgotten tap off isn't refundable.
