Streaky Bay is a remote fishing and holiday town on a large, shallow, sheltered bay on the west coast of Eyre Peninsula. Its town jetty is a shallow, easy shore dive included here as one of the named Eyre Peninsula jetties; there is little specific published dive information about it. The jetty stands over sand and seagrass in 2-5 m.

Its piles carry algae, sponges and ascidians with crabs, nudibranchs and small fish, and schools of tommy ruff, garfish and King George whiting gather around it. Squid are drawn to the lights at night, blue swimmer crabs and stingarees are common, and the vast seagrass meadows of the bay support a rich nursery fauna. Dolphins are regularly seen.

The Marine Life Society notes the area is famous for its unusual mainland colony of Australian sea lions at Point Labatt, south of town, which can be viewed from a clifftop lookout – access to the water there involves a demanding and dangerous cliff climb, and the colony should not be disturbed. The sea lion and dolphin swims at Baird Bay, 50 km south, are the region's main in-water wildlife experience. The jetty suits snorkellers and travelling divers wanting an easy shore dive.

Data confidence is low.

Streaky Bay is on the Flinders Highway about 300 km north-west of Port Lincoln and roughly 700 km from Adelaide via Port Augusta and the Eyre Highway (with a turn-off at Poochera). The jetty is on the foreshore in the town centre beside the pub and swimming enclosure. Park at the jetty head and enter via the steps or beach.

The west coast of Eyre Peninsula faces the Great Australian Bight and receives almost constant south-westerly Southern Ocean swell; open-coast sites need swell under about 1.5 m and are only diveable a handful of days a month, usually after several days of northerly or easterly winds, which blow offshore. The large sheltered bays (Coffin Bay, Waterloo Bay, Venus Bay, Baird Bay, Streaky Bay, Denial Bay) are protected from swell and can be dived in most conditions except strong onshore winds. Summer brings strong afternoon south-easterly sea breezes; winter brings cold fronts with big swell but also calm, clear spells.

Water is cool: about 14-15°C in winter and 17-21°C in summer.

Swim out along the piles to the end, search the growth and seagrass, and return; squid at night.
