There were once only about 5,000 crocodiles in the Northern Territory. The population was decimated in the late 1940 and 1950s by hunters. A ban was placed on hunting and the exportation of skins in the early 1970s. Croc numbers have bounced back and are now estimated at 70,000.
I took this photo of a crocs eye today in Darwin –

Dr Grahame Webb was involved with the program to rebuild croc numbers. He told me the following three principles were promoted:
1. public education;
2. a program to contain problem crocs including trying to keep crocs out of Darwin harbour;
3. ensuring crocs had a commericial value – so landholders saw them as an economic asset rather than a pest.
About 20,000 eggs and 600 crocs are harvested from the wild each year under a permit system. Eggs sell for about $40 each while crocs sell for perhaps $500.
Many locals wish there weren’t so many… so they could swim at the beach again.
