We do try to provide as much information about the road tolls as possible so that you can set up your toll pass.
Unfortunately for any tolls that are not paid for we receive notices- we then need to complete statutory declarations to nominate the driver. The $20 administration fee is to cover the time and cost to complete this.
The tolling system is frustrating as it is outside of our control. We do our best to make it as easy as possible and provide the cheapest way to pay the tolls.
