What is the default/penalty fare on rail? The default/penalty fare will depend on which Station you tag on at. The amount charged will be a Snapper fare for the longest possible travel from the tag-on station to a maximum of $10 for adults, $2.50 for children, $5 for passengers with Accessible, Community Connect and Young Adult concessions, and $7.50 for passengers with a Tertiary concession. Any default/penalty fare will come off your Snapper balance the next time you tag on a bus, rail or cable car trip. If you do not have enough balance on your card to cover the default/penalty fare, you will be unable to tag on until your card is topped up with sufficient credit.
