What is a top-up amount?
This is the amount of money used to replenish your RTA E-Toll account when your minimum account balance is reached. For frequent user accounts the minimum top-up is $80 per tag. For infrequent user accounts the minimum top-up is $20, with a maximum of $70 per tag. Please note: For infrequent user accounts, the RTA may increase your top-up amount, rounded up to the nearest $10 and to a maximum of $80 per tag, to cover your average monthly spend on tolls (based on your spend over the previous three months). When the calculated top-up amount is more than $80 per tag, you will cease to be an infrequent user and become a frequent user.
