What a sight!

A Far North Queensland fisherman has captured amazing footage of a monster croc racing alongside his boat on the Bloomfield River.

Alec Dunn was heading out to check his crab pots in Bloomfield, when the approximately four-and-a-half-metre saltwater crocodile pooped up beside him, swimming through the water like a dolphin.
