Bull Shark
Bull Sharks are considered one of the most dangerous sharks in the world, so people should be aware that they like to come to Sydney for their summer holidays. They are generally big (about 3 metres) and they just love hanging about in Sydney Harbour and heading inland.
Fortunately these sharks are pretty timid and they try to avoid us like the plague. If they didn't, we certainly wouldn't be jumping into the water during the summer months and shark attacks would be front page news on a daily basis.
The problem comes when they can't see us and have an accidental nibble and they definitely can't see us in murky water at dusk. If you live inland and fancy an evening dip in an unprotected area, may we suggest you have a bath instead.
