Steve makes alot of money being an "Aussie", mostly from overseas, and good luck to him but he is only working a set image and is not typical of most Aussie croc wrestlers. He is way too nice, unarmed and sober.
The outback can kill you in half a day if you do dumb things like travel with no water, spares and the like, and people keep doing this time after time. Then there are the snakes and bities not to step or sit on. If you take care and think about things you are as safe as anywhere else. Kind of like taking a hike in Northern Canada in winter and leaving your jacket home because it looks like a nice day.
In the north of W.A, Northern Territory and Queensland there are big crocs that like to eat things that swim in the water. There are even signs that say "Don't swim here or a croc will bite your arse" but this doesn't stop locals and tourists from having a dip. Then when they get taken it's all "kill the crocs" and "croc terror".
I was once in far north Queensland when after miles of dirt roads and rainforest my friend an I arrived at the beach/coast to set up camp. On our right some 100 metres were 4 topless girlies with a Kombi sunbaking on the sand. On the left some 100 metres were 3 saltwater crocs sunbaking on the sand. After eleventeen beers we did what all good Aussie boys do and kicked sand in the crocs faces. The girls were English tourists and the crocs were prettier and had better teeth
Then there are sharks, box jellyfish, dropbears and Italian Duck Hunters...
