A stones throw from Sydney, the picturesque seaside retreat of Kiama is one of the South Coast's favourite tourist destinations.

The Kiama Headland is composed of volcanic rock called latite. A volcanic extrusion, known as a dyke cuts through the latite. The dyke is composed of a softer rock called basalt.
Over millions of years the softer basalt has eroded faster that the latite creating a tunnel under the headland collapsed creating the Kiama Blow Hole.
As each wave surges through the tunnel air is compressed in the rear chamber building tremendous pressure. As waves subside, pressure in the chamber releases forcing the trapped water up the blowhole with a loud 'whoomp'.
