A LOCAL shark expert said a 3m great white shark was sighted off Julian Rocks three weeks ago, with the sharks a common sight in Byron coastal waters.
It is common for great white sharks to be sighted at Byron Bay, with juveniles in the bay year-round, Dr Danny Bucher from Southern Cross University said.
Dr Bucher, senior lecturer in marine biology and fisheries at the university, said while juvenile great whites were common year-round at Byron Bay, it was unusual for a larger shark to be in the bay itself.
The bay is not a private swimming pool. These are wild animals.

"Only three weeks ago a colleague of mine sighted a three-metre great white at Julian Rocks," Dr Bucher said.
"The larger sharks would be heading south at this time of year for the seal pup season, Dr Bucher said.
Dr Bucher said schools of mullet or Australian salmon may have drawn the shark into the bay, but he warned there was little that could be done beyond taking the normal precautions of not swimming at dawn or dusk; in murky water or close to schools of fish.
"The bay is not a private swimming pool. These are wild animals."
Dr Bucher said it was extremely rare for the same shark to be responsible for a sequence of attacks and that there was no evidence of 'a plague of sharks'.
