THEORY 1: If dolphins are around you won't be attacked by a shark FALSE

"So many people think if there are dolphins in the area there aren't going to be sharks around.If there are huge schools of fish it is quite common that sharks and dolphins will feed in close proximity of each other. I have seen sharks and dolphins swimming together." Michael Brown, researcher for Surfwatch Australia
THEORY 2: Hitting a shark on the nose or eyes will deter them TRUE
"The snout is the most sensitive area of the shark, it's full of very delicate organs that detect minuscule electrical impulse — such as the heartbeat of a fish. Great whites roll their eyes back in to their skull — preserving their eyes is important." Vic Peddemores, senior research scientist, NSW Department of Fisheries
THEORY 3: Swimming with dogs increases the risk of attack INCONCLUSIVE
"There is currently no reliable scientific information confirming whether swimming with a dog increases the risk of being bitten by a shark. While sharks can be attracted to sound, most swimmers make more sound than a swimming dog." Dr Charlie Huveneers, ecologist at SARDI Aquatic Sciences
THEORY: 4 Bright colours attract sharks TRUE
"There is definitely something in the 'yum, yellow' theory and in dirty water sharks will investigate brighter colours more readily than the dull or dark colours. I am always more vigilant with divers using bright-coloured fins." Mark Addison, shark expert and film-maker
THEORY 5: Urine attracts sharks FALSE
"I would have been dead a long time ago - there is no evidence that urine attracts sharks. I have been in the water close to large sharks like a tiger shark and have weed, and it makes no difference." Vic Peddemores, senior research scientist, NSW Department of Fisheries
THEORY 6: Sharks can be stared down TRUE
"I find eye contact to be a critical moment in diver/shark interactions. Once you make eye contact they [can] back off. They are looking for a stealth moment, or an opportunity to investigate an unsuspecting quarry rather than an aware one." Mark Addison, shark expert and shark film-maker
THEORY 7: Sharks attack to feed TRUE
"Most attacks are mistaken identity regarding prey. In NSW a lot are juvenile great whites — changing diet from fish to mammals. There is no mum, and they have to take a chance. Sometimes it's human." Vic Peddemores, senior research scientist, NSW Department of Fisheries
