The captured crocodile was tightly bound to the cart.
Measuring 4.7 metres and weighing in at up to 600 kilograms, the snappy saltie was trapped by rangers in Taylor's Park, around 60 kilometres downstream from the Top End town of Katherine. At the gorge there are freshwater crocodiles, which are smaller and rarely harm humans.
Following a almost decade-long hunt, a massive saltwater crocodile has been captured in northern Australia, according to wildlife authorities.
"On record, this is the biggest saltwater crocodile removed from the Katherine management zone", Ranger John Burke said.
While the average saltwater crocodile is 17-feet-long, captures of this size are rare, wildlife authorities told CNN.
While large crocs are territorial, Webb suspected the trapped croc had moved to and from the area where it was caught during the past 10 years.
The largest crocodile caught in a "trap" was more than 16 feet (4.8 metres), and the largest one "harpooned" by rangers was also more than 16 feet (4.8 metres), it states. Satellite tracking had shown one croc tagged in a Northern Territory waterhole had swum 900 kilometers (560 miles), for unknown reasons, before returning to the same place.
Saltwater crocodiles are a protected in Australia.
"That sort of croc, in my opinion, is the most risky to people", Webb said.
"They were surprised because it's unusual to find a croc of his size in that area", she said. "This is the biggest saltwater crocodile..."
The crocodile population has exploded since they were declared a protected species in the 1970s, with the killing of an elderly woman previous year reigniting calls to curb their numbers.
