Troy Cassar-Daley calls in about his experiences in far north Queensland in croc-infested waters and how locals know when an animal is about…

And the way they can recognise a crocodile is nearby is definitely not what you’d think.

The story comes after the tragic news of a crocodile killing Cindy Waldron who was swimming in northern Queensland earlier this week. 

The attack happened north of Cairns after the woman was swimming with a friend at approximately 10:30pm on Sunday night. 

Swimming with a friend, the two women were waist deep in water before the attack occurred.
