In Victoria the bus is 2.25 for adults, not sure how much for students/seniors, maybe 1.75. You get a transfer slip and use it for a return/connecting trip if it's within an hour.
The bus service is pretty good around here, except it ends too early (12, 12:30) IMO. A bus passes the end of my street every 1-15 mins. It goes through downtown (from there you can transfer to buses that go pretty much everywhere) and to the main local university.
