From Ritchies Buses

They are replacing the old yellow $28 tickets with new tickets. 

The process will be that as old tickets are presented to the driver they will be replaced with the new ticket and the driver will punch the necessary number of rides so it will be like for like.
The drivers will accept (and replace) the old tickets for the first two weeks of term (until 28 July).

After this date, old tickets can still be replaced at our Swanson Depot, 572 Swanson Rd, Swanson.
