Three-metre shark sighted in the shallows of popular beach off the Fleurieu Peninsula

A shark has been spotted in the shallows of a stretch of beach between Carrickalinga and Normanville in the middle of the day as beach goers enjoy a lunchtime beach stroll.

SharkAlert SA posted the sighting of the ‘Mystery Brucey’ suspecting this may be the same shark spotted at Maslin’s and Aldinga in the previous week.

In the video, Lexi Grabb, who handed the footage to SharkAlert SA, is walking along the beach recording the shark in waters so shallow, both its massive fin and tail can be seen poking out of the water.

The shark is estimated to be about 3m in length, with SharkAlert SA telling it’s followers that it could be a “pointer”.

A white pointer is a great white shark, and can grow from 4m to almost 6m in length depending on sex, with the females often being larger.

Great whites are locals in South Australian waters, and feast on the local fish such as Salmon.

Juvenile white sharks (less than 3 to 4 m) mostly feed on fish and squid.

As they grow, their diet changes to include other sharks, rays, and marine mammals.

White sharks are protected at all times in all South Australian waters under Section 71 of the Fisheries Management Act 2007.

A person must not take, harm, or harass a white shark.

Carrickalinga Beach draws in thousands of tourists each year, with many taking to social media to show off the rockpools along the pristine coastline.

Beachgoers are reminded to be aware of their surroundings and to avoid swimming near food sources like large schools of fish.

PIRSA would like to remind the public that using blood, bone, meat, offal, or animal skin (other than a fish, worm or insect) for berley is prohibited in SA waters and should be reported to the 24-hour Fishwatch hotline on 1800 065 522.
