"We were pretty amazed, we were turning up to shoot a flooding road, we weren't expecting to see wildlife as well."
Bull sharks are common in the area, according to Calder, and many of them live in creeks and rivers close by to nearby communities.
The Burdekin River, located in North and Far North Queensland, is known to house bull sharks, turtles and barracudas.
Calder said the shark is "the talk of the town", while "a lot of people are turning up to touch it. They are pretty excited by it".
Despite being in the firing line, Ayr received only moderate flooding.
"We've escaped the brunt of the cyclone, we're pretty relieved," Calder said.
