Swimmers and surfers are being urged to avoid a number of beaches on the south coast of New South Wales as a rotting whale carcass causes a shark feeding frenzy.
One drone operator spotted a massive shark on Friday swimming near the shore and close by a boat at surf break Peggys after a "significant number of sharks" were spotted between Sandon Point and Bulli Beach.
"Safe to say I won't be surfing Peggys for a few days," Geo Mattis wrote on Instagram sharing photos videos of the mega shark.
Illawarra Council closed beaches at Bulli, Thirroul, Sandon Point and Woonona, and lifesavers urged people not to exercise on the sand.
