Three crocodiles relocated from their homes in Far North Queensland have been tracked swimming between 10 and 30 kilometres per day according to a collaborative research project by The University of Queensland, Australia Zoo and Queensland Parks and Wildlife Service.
Professor Craig Franklin, from the University's School of Integrative Biology, said one relocated crocodile swam around the northern tip of Australia to reach home covering more than 400 kilometres in 20 days.
We often thought crocodiles tired very quickly but here we show very clearly that they are capable of moving long distances for days on end," Franklin said.
The results come from the first satellite tracking study of wild crocodiles undertaken by the collaboration and led by Dr Mark Read (QPWS), Professor Franklin and Steve Irwin and funded in part by a generous bequest from the late Charles Tanner, a herpetologist who lived most of his life in Cooktown, and a grant from the Australian Research Council.
The crocodiles were tracked using a specially-designed transmitter attached to the back of their heads that collected the data and relayed it via satellite back to the scientists.
The results highlighted the success of satellite tracking for crocodiles allowing continuous tracking without human interference.
Professor Franklin said Satellite technology is a great way of tracking these really cryptic animals which are difficult to follow.
"The success of the study was also recognition of the skills and knowledge that Steve Irwin brought to the project."
He said Steve Irwin was a major driving force behind the study, and his intellectual and logistical support complimented the knowledge, experience and contributions made by the other team members.
"He also gave us the assistance of the croc team from Australia Zoo, who are highly skilled in the capture and care of crocodiles."
