Australian saltwater crocodiles were once hunted so mercilessly that fewer than 3,000 existed in the Northern Territory. Then, in 1970, crocodiles were given a protected status in the area, an act that has seen their numbers skyrocket to 100,000. Similar population growth has occurred in Queensland although the exact numbers aren’t known.
Thankfully, attacks on humans by salties are relatively rare. However, the sheer number of crocodiles and their increasing contact with humans means that on average there are one or two fatalities every year. 2014 was an especially bad year, with four people losing their lives.
