The submerged reef with cardinal marks and danger mark.

Sow and Pigs Reef is a rocky reef in

Sydney Harbour, New South Wales, Australia. The reef is situated on the eastern side of the main shipping channel between Middle Head and South Head
. It is 150 metres (490 ft) long and up to 70 metres (230 ft) wide. Originally the reef was exposed and resembled a sow and her litter. Explosives were used to reduce the reef, however, and now the reef is only exposed at a very low tide. A number of ships have been wrecked or damaged after hitting the reef.
