Tasmania is largely made of dolerite, an Australian rock, however the Bicheno Blowhole is made of granite. The ocean has beaten the granite for thousands of years, carving out a sea cave beneath the coast. The water, which was assaulting the cave’s interior with increasing intensity, located a weak area in the ceiling and used it to rip a hole in the granite. Now, water rushes into the cave, splatters against the walls, swells under increasing pressure, and erupts out the ceiling hole. For those standing on top of the sea cave, this provides a geyser effect.

With each surge of the ocean, the geyser bursts with changing force, and the water takes on new shapes. Even when the sea is calm, it can blow with enormous force, so never turn your back on the blowhole. When the ocean is angry, though, the most spectacular and dangerous eruptions occur.
