The latest addition to the Ballarat Wildlife Park, Crunch, a saltwater croc weighing about half-a-tonne, put on a spine tingling show for hundreds of tourists. 

With a crowd of more than 100 people watching, Crunch took the opportunity to sprawl his massive body out of the water and munch on some delicious fish. 

Park manager Stuart Parker said the croc, believed to be about 60-years-old, would go on to provide one of the best crocodile shows in the world. 

"There is no doubt that this croc is special," Mr Parker said. 

"He's already showing signs that he is a bit different."

Mr Parker said saltwater crocodiles often took years to warm up to a new location after a big move. 

But he said Crunch was already doing things far in advance. 

"In a short amount of time he will be part of one of the best croc shows in the world," he said. 

Crunch replaces Gator, the park's previous showcase croc who died suddenly in May last year. 

Crunch grew up in rivers around Cape York where he was deemed a problem due to his size and aggression. 

Captured about seven years ago, Crunch has spent the past few years at a farm in North Queensland. 

He was transported to Ballarat by truck.
