North-east NSW coastal waters since 1850: a 'hot spot' for shark numbers

 

There are 8 real-time, satellite-linked VR4G listening stations deployed in approximately 10 to 12 metres depth of water approx. 500 metres offshore along the stretch of coastal waters off the Northern Rivers region in north-east New South Wales.


These listening station buoys are located at:

Kingscliff Beach, Tweed Heads

Clarkes Beach, Byron Bay

Lennox Point, Lennox Head

Sharps Beach, Ballina

Lighthouse Beach, Ballina

Main Beach, Evans Head

Main Beach, Yamba.

In 2023 the total number of shark detections at each of these 8 listening buoys were:

Kingscliff Beach - 305 (302 Bull Sharks & 3 White Sharks)

Clarkes Beach - 409 (213 White Sharks & 196 Bull Sharks)

Lennox Point*         | These 3 sites combined

Sharps Beach*        | 2,026 detections of

Lighthouse Beach* | 1,175 Bull, 755 White & 116 Tiger sharks

Main Beach, Evans Head - 3,135 (3,031 Bull Sharks & 96 White Sharks)

Main Beach, Yamba - 17,501 (17,306 Bull Sharks, 103 White Sharks & 2 Tiger Sharks).


Although in 2023 Yamba might have been the main contender for the title of shark capital of New South Wales, particularly in the months of April to August, there have been zero fatal shark attacks in Yamba river or ocean waters since 1850 and, only 37 injuries resulting from contact with a shark recorded by the Australian Shark Incident Database in that same 174 year period.



As for the entire coastline of north-east NSW along with its saltwater river mouths, from the Clarence Valley up to the NSW-Qld border, there have been est. 361 interactions with sharks resulting in injury since 1850, including est. 37 deaths.
