The tourists had paid for a close-up view of crocodiles – and when this beast burst from the water they certainly got their money’s worth.
For when it comes to crocs, they don’t come much bigger than Brutus.
Lured by a tour guide dangling kangaroo meat from a pole, the 18ft, two-ton monster was, er, snapped by photographer Katrina Bridgeford, who was on the Adelaide River cruise with her family.
‘It got the adrenaline going,’ Australian Mrs Bridgeford said. ‘It was so close you could almost touch it.’
She recalled that when her son Dylan, 11, saw the massive creature rise out of the water he had only two words to utter - 'Holy crap!'
Brutus is missing his front leg following what is believed to have been a confrontation with a shark in the river's estuary - leaving many people to wonder just how big the shark was.
'When it came up out of the water there were a lot of "Oos" and "Ahs",' said Miss Bridgeford.
'I wasn't expecting anything like this. I couldn't believe how close it got to us.
'If you had put your hand out you would have been able to touch it - if you'd dared.'
Jumping crocodile cruises are a major tourist attraction in the Northern Territory, where the Crocodile Dundee movies, starring Paul Hogan, were shot.
Thousands of the monsters live in waterways around the Darwin region, resulting in the local government erecting signs in tourist areas warning people not to swim or wash their vehicles in the water.
They are also told not to camp near rivers because crocodiles roam up to a mile inland.
Several people have been killed by the reptiles over the years.
Three people were taken by crocodiles in northern Australia in 2009 alone, including an 11-year-old girl who was playing with friends in the Black Jungle Swamp near Darwin.
