The Latest Crocodile Attack Is Tragic But The Northern Territory Doesn't Have A Croc Problem


Author: Brandon Michael Sideleau

(MENAFN- The Conversation) Late last week, the remains of a missing 12-year-old girl were found after she was taken by a saltwater crocodile in the Northern Territory.

The incident occurred in a waterway known as Mango Creek near the community of Nganmarriyanga/Palumpa in the remote and sparsely populated West Daly region, about 350 kilometres southwest of Darwin.

Understandably, the tragedy elicited a strong reaction from the public – including debate about crocodile numbers in the wild.

I am based in the Northern Territory and have worked extensively in the field of human-crocodile conflict management, including establishing CrocAttack , a global open-source database of crocodilian attacks. Amid the emotion surrounding this latest incident, it's important to remember fatal crocodile attacks are extraordinarily rare in Australia – and there is no evidence to suggest their numbers are too high.

Saltwater crocodiles in NT number about 100,000 (excluding those just hatched). Research shows about five crocodiles, on average, for every kilometre of waterway in the territory.

Fatal crocodile attacks in the NT peaked in 2014 when four people died. Prior to the latest incident, the last fatal attack in the NT occurred in 2018 when an Indigenous ranger was killed while fishing with her family.

The fatality rate is far lower than elsewhere in the saltwater crocodile's range. In Indonesia, for example, at least 85 people were killed last year alone . What's more, crocodile incidents in Indonesian Papua are believed to go largely unreported, so the number of actual deaths is likely much higher.

Despite this, there appear to be vastly fewer crocodiles in Indonesia. Most surveys reveal densities of significantly less than one individual per kilometre in waterways.

There are several theories on why saltwater crocodile attacks are comparatively rare in Australia.

First, Australians generally have access to fresh water in their homes. Unlike people in, say, Indonesia, they do not need to travel to waterways to bathe, carry out domestic chores and collect drinking water. That means they are less likely to encounter crocodiles.

Second, Australians have access to fishing equipment which does not require them to submerge themselves in waterways to fish , and safer fishing vessels which, unlike in Indonesia, are not prone to capsizing .

The Northern Territory is also more sparsely populated and developed than other areas where saltwater crocodiles live. That means less habitat destruction, more natural prey for crocodiles, and fewer people in crocodile habitat.

Importantly, the Northern Territory also has an extensive crocodile safety education program in the form of the CrocWise campaign , as well as a robust management plan .


The NT has an extensive CrocWise campaign. Crocs don't need culling

The NT crocodile management plan was recently amended to increase the territory's crocodile removal quota from 300 to 1,200 a year, stopping short of a widespread cull.

However, each time a croc attack is recorded in Australia, it provokes debate about whether tougher management of croc numbers is required.

Following the latest crocodile attack, NT Chief Minister Eva Lawler told the ABC:

Claims that crocodile populations need“controlling” make little sense. Research shows apex predators such as crocodiles do not overpopulate. Crocodile numbers in the Northern Territory have never been, and will never be, out of control.

This is particularly true for the saltwater crocodile, for which less than 1% of hatchlings survive to adulthood . It is also a fiercely territorial species , and conflict between males often results in death.

A 2015 Australian study found removing all crocodiles from a location was not a practical option, given the species' mobility and dispersal across a range of habitats. It said culling programs would not ensure the absence of crocodiles in a targeted area and swimming activities would remain unsafe to the public.

Other Australian research has found crocodile numbers would have to fall by 90% to prevent one annual attack.

Preventing crocodile attacks in the Northern Territory requires more community education, more signs warning of the crocodile danger, and tougher fines for people wilfully engaging in unsafe behaviour.

New tools are also being developed. This includes detecting crocodiles with multi-beam sonar in areas where the attack risk is high, and attaching magnets to crocodiles while moving them to disrupt their natural homing instinct. These methods require further studies.

Ultimately, through public education and management, it is possible for humans to live alongside crocodiles with minimal conflict.
