CROCO-METRE - SOME OF THE WORLD'S LARGEST CROCODILES
* Cassius, the 5.48m giant holds the Guinness World Record for being the largest croc currently in captivity. Housed on Green Island in far north Queensland, he weighs more than one tonne and is believed to be more than 110 years old.
* The world record was previously held by Lolong in the Philippines. Lolong measured a massive 6.17m before died in 2013.
* Gustave, who resides in the Ruzizi River in Burundi, is thought to be the biggest crocodile currently alive. He's estimated to be 6m long and is rumoured to have killed more than 100 humans in his time near Lake Tanganyika.
* Polish immigrant Krystina Pawlowski claims she shot an 8.6m crocodile on the Norman River near Queensland's Gulf of Carpentaria in the 1950s. It's Australia's largest known crocodile but its size has never been verified.
* Australian outback wrangler Matt Wright is thought to have caught the country's second-largest crocodile in the Northern Territory in late 2015. It measured 5.58m.
* Well-known Northern Territory reptile Brutus, located in the Adelaide River, is estimated to be about 5.5m in length.
* Brutus has even even bigger nearby neighbour. Dominator has never been officially measured but it's estimated he measures up to 6.1m.
* A 5.2m saltie was found floating in the Fitzroy River near Rockhampton on Thursday with a gunshot wound to its head. Local croc farm owner John Leaver says a beast that size has not been caught in Queensland for 30 years.
