Tolls and GST
An important note about EastLink tolls and GST:
As required by law, the advertised toll for each individual section of EastLink includes GST.
However, a single trip you take on EastLink may pass through several sections. The charge for this kind of trip is calculated by adding up the tolls for each section included in your trip. Because of the way GST is applied, there will sometimes be a small rounding difference in the actual charge for this kind of trip. This is explained below.
EastLink's tolling system adds up the tolls for each section of EastLink without GST, and then applies GST to the total. This means that the actual charge for a single trip passing through several sections of EastLink could be one or two cents higher or lower than the total of the advertised tolls for those individual sections of EastLink.
