Pumicestone_Passage
Pumicestone Channel
Strait in Queensland, Australia
Pumicestone Channel, also known as the Pumicestone Passage, is a narrow, mesotidal waterway around 45 kilometres in length, between Bribie Island and the mainland in Queensland, Australia.[1] The northern extent of the passage is at Caloundra, while at the south is Deception Bay. The waterway is a two way tidal estuary that has 11 creeks flowing into it.[2] At each end of the passage the channels are the deepest and widest.[2]
During periods of unusually high tides and large waves, the passage is infiltrated by inflows through channels in dunes at the northern tip of Bribie Island.[3]
