Prefer the freedom of a motorcycle? Don't like paying bridge tolls? Then this traffic hack will save you cash, all by simply switching your billing method with the Roads and Maritime Services. If you ride a motorbike over the Harbour Bridge frequently, you can get a special toll account from the RMS which gives you unlimited access to the Harbour Bridge or Tunnel for $90 a quarter.
So let's say you cross the bridge five times a week – 3 months of the normal toll cost would $260 – so you'd save around $170 a quarter. Really, you only have to cross the bridge a couple of times a week for this to offer some decent savings. Best of all, you don't need to carry an E-tag – instead your number plates are matched and you are subsequently charged.
