Cockle Bay is a small bay in inner-city Sydney, New South Wales, Australia.
When the First Fleet reached Sydney Cove in January 1788, a consignment of 5,000 bricks and 12 wooden moulds for making bricks was included in the cargo carried by the transport Scarborough. This token consignment was adequate enough to enable the first settlers to make a start on the colony’s first buildings, until the location of a suitable site for brick-making could be found. A site deemed suitable for this endeavour would need to have a plentiful supply of clay and a ready source of fresh water. Approximately a mile from the settlement, at the head of a long cove (and consequently so named), a suitable site for brick-making was located. This site was later named Cockle Bay, and still later, Darling Harbour.
