Super small stop for the Neutral Bay Ferry (F5), first as you leave Circular Quay. There are a couple of seats and a small coffee shop, that's open breakfast & lunch only.
There are machines to top off your Opal card (or even purchase one if need be). The steps down to the ferry (or up to the street) are a bit difficult if you're not super mobile (or are dragging a roller bag after a 20 hour flight).
Ferries are typically every 30 minutes at this spot. Still you can commute on a ferry which is awesome. read more
