But that's where Goulburn man Peter Caldwell found himself last Sunday morning as he strolled around one of his favourite spots, Marsden Weir.
Armed with his Canon SD Mark 4, he watched what he thought was a water rat swim around the base of the wall, where people commonly fish.
All of a sudden, the rat jumped from the water with a large red fin in its mouth. Mr Caldwell managed to snap the tussle.
"The light was just right and it was one of those freakish shots," he said.
Further research back home revealed it was indeed the rakali, more commonly known as the water rat. It is sometimes referred to as 'Australia's otter.'

Mr Caldwell said he'd enjoyed amateur photography for the past 25 years but had become more serious about it in recent years. On Sunday he was keen to try out a new lens.
"I enjoy taking photos around Goulburn and landscape (images)," he said.
"I (also) love being around the water and the weir because it attracts all sorts of native species."
He intends to enter the image in a photo competition.
Marsden Weir has become a mecca for photographers and exercisers since the Wollondilly Riverwalk was installed. A council tracker registered an average 292 walkers and 70 cyclists using the 12km path each day, general manager Warwick Bennett recently told The Post.
Design is underway for an extension from Riversdale over around the Correctional Centre. This involves talks with Corrective Services on the best route.
Mr Bennett said the walkway should stretch to 18km by the end of the financial year.
