Several teeth have already been stolen from the dead mammal and Department of Environment and Primary Industries senior biodiversity officer Mandy Watson has warned people that approaching or interfering with the carcass was illegal and a risk to health and safety.

“The department strongly advises beachgoers, swimmers and surfers to stay well clear of the area,” she said.

“The carcass is a health risk, containing bacteria and potentially harmful pathogens.

“As it decomposes, it releases oil and fluids into the ocean which could attract very large sharks.

“Under the Wildlife Act it is illegal to interfere with a whale, whether dead or alive, and severe penalties apply.”

Museum Victoria has indicated it wants the carcass collected for examination.
