Looked through the NSW's website on public transportation, there are a number of options for unlimited access. The most comprehensive option is the SydneyPass, which costs $170 for 7 days including RT AirportLink. However, I also found the Red Travelpass covers a lot of ground (& water) within central Sydney, but only costs $38 for 7 days. I realize the Red Travelpass doesn't cover the Sydney nor the Bondi Explorer, but if I figure the regular system would get me to those places, too. Hence, is it worth paying extra to get the SydneyPass? TIA.
