Weekend range
Sites within roughly 110 km straight-line distance of central Sydney, ordered by how regularly they are dived and how well they are documented.
Sydney has more dive sites within a two-hour drive than any other capital in the world, and most of them are shore dives. This list ranks the sites within about 110 km of the CBD by how regularly they are dived and how well they are documented, from the Harbour and Botany Bay to the Central Coast and Wollongong.
Winter westerlies (June–September) give the flattest seas and clearest water; in summer dive early before the nor'easter.
