The Kiama Blowhole is a blowhole in the town of Kiama, New South Wales, Australia. It is the town's major tourist attraction. Under certain sea conditions, the blowhole can spray water up to 25 metres (82 ft) in the air, in quantities that thoroughly drench any bystanders. There is actually a second, less famous blowhole in Kiama, commonly referred to as the "Little Blowhole" by locals. It is much smaller than the other (called the "Big Blowhole"), but due to its narrow shape, it is actually more reliable than the Big Blowhole, and in the right conditions can be equally spectacular.
The blowhole attracts 600,000 tourists a year. Kiama Blowhole is just a few metres beyond the coastline. The "little blowhole" is located a few minutes south of the main blowhole.
