The Blowholes, Cape Bridgewater, Victoria
If you follow the track from the other side of the car park, you will come to a series of blowholes. Rock tunnels have been carved out of the volcanic rock over time by the waves, and when the seas are rough, the spray can reach quite high.
The viewing platform upon which I was standing (38°22′44.22″S, 141°21′59.44″E) (Google Maps), provides a great view of some of these blowholes and Discovery Bay.
