Kiama, ky A muh, is a seaport on the Illawarra coast of New South Wales, Australia. It offers a shallow anchorage harbor. Tourist attractions include the blowhole, a basalt rock formation that resembles a high arched cavern. When the sea is rough, water is forced upward through this feature creating a high spray. Saddleback Mountain Lookout provides a scenic view of the entire Illawarra coast and the Jamberoo Valley.
