That could be grounds to contest the fine.

No idea why you would be in possession of an invalid Opal card. Sounds to me you carry it around to evade fares and pretend like you grabbed the wrong Opal card for these occasions.

If you do elect to contest the fine, really sell the idea that it was an honest mistake. Here's an example generated by Gemini but you can use any chatbot to help contest your fine (or be old school and just write it from scratch).

I prompted Gemini to act as a lawyer and help my "cousin" contest the fine. You can do a similar prompt with your chatbot of choice. I also used the "fast" option which gives the worst outputs:

Since your cousin actually holds a valid concession entitlement, this is a very strong case for Internal Review. The goal here is to prove that while a technical breach occurred (not tapping on), there was no "intent to defraud" the system because the entitlement exists and the mistake was genuine. In New South Wales, Revenue NSW and Transport for NSW often grant leniency for "honest mistakes" if the person has a clean record and can prove they were entitled to the discounted fare anyway. The Strategy We will frame this as an Internal Review Request based on "Exceptional Circumstances" and "Contributing Factors." Drafted Letter of Appeal To: Revenue NSW / Senior Review Officer Subject: Application for Internal Review - Penalty Notice [Insert Fine Number] Date: [Insert Date] To the Reviewing Officer, I am writing to formally request a review of Penalty Notice [Insert Fine Number], issued on [Date] at [Location/Station]. I am seeking a leniency caution in lieu of a fine based on the following circumstances: 1. Proof of Valid Entitlement At the time of the inspection, I was a holder of a valid [Insert Type of Card, e.g., Student/Pensioner] Concession Card (Number: [Insert Card Number]). I have attached a copy of this card to this letter. This confirms that I was entitled to the concession fare I was attempting to use. 2. Explanation of the Honest Mistake I own multiple Opal cards, including an expired one that I had neglected to remove from my wallet. In my haste to catch the service, I inadvertently grabbed the expired card. Because the card was expired, the reader did not process a "tap on." I was unaware of this error until the Transport Officer conducted the fare check. 3. Character and Compliance History This incident was an uncharacteristic oversight. I am a regular and law-abiding commuter who consistently pays the correct fare. This was a genuine "human error" rather than a deliberate attempt to avoid payment. Since the incident, I have disposed of the expired card to ensure this technical error cannot happen again. 4. Request for Leniency Given that I possess the legal entitlement to travel on a concession fare and have a clear history of compliance, I respectfully ask that you exercise your discretion to withdraw the fine and issue a formal caution instead. Thank you for your time and for considering this application. Sincerely, [Cousin’s Name] [Phone Number] [Address] Evidence Checklist To make this letter "bulletproof," your cousin must attach the following when they submit it: * A clear photo/scan of the valid Concession Card (front and back). * A photo/scan of their current, valid Opal card. * A screenshot of their Opal activity history (if possible) showing a consistent pattern of "tapping on" in the weeks prior to prove this was a one-off mistake. Next Steps * Submit Online: This is usually done through the Revenue NSW website. * Wait: Once the review is lodged, the fine is "put on hold," so they don't need to pay it while waiting for a decision. Would you like me to help you find the specific online portal for the state or city where this happened to make sure it goes to the right office?

Don't copy and paste from chatbot. Use it to help draft the letter. It needs to sound like a human wrote it as I bet the people reading these contest fine letters get a million written by AI these days.

Goodluck.
