Ha! I don't want mislead you, in that I'm also a 'local' albeit from several thousand kilometers south of Cape Tribulation (Australia is a very big place). Thus, I'm familiar with much of the flora and fauna that seems to terrify people from other parts of the world (it's just that this was my first visit to these parts).
The Emmagen Creek 'local' was someone who I already knew, he used to work for me in electronics but chucked it in to 'go bush' with his better half and ended up taking over a disused tin-mining lease under the pretext of prospecting for tin but in reality he did little other than to loll around eating papaya which grew everywhere around his dwelling.
Somehow or other he invited me and another colleague to visit him and we agreed although it was very inconvenient for me at the time. (I had university assignments to complete—so when not trekking about in the bush you can picture me doing formal logic assignments sitting on a stump in that wilderness. Getting the assignments back to the uni in a timely manner was a somewhat fickle hit-and-miss process—I had to pay the local hippies who lived on the beach some miles away rather handsomely to take them to Cairns to post whenever they went there to collect their dole payments.)
Australia isn't really that bad, not that many of us fall victim to or are gobbled up by the wildlife every year but it does happen. We locals are rather blasé about wandering in the 'bush' without much protection—hazmat suits would be deemed totally unnecessary. Though the Daintree Rainforest probably has more to be concerned about than many other areas, there are crocodiles in the larger rivers and you'd be advised not to swim in them, also the cassowarys can be quite aggressive, especially so when nesting (see heading 'Attacks'): https://en.m.wikipedia.org/wiki/Cassowary.
I got a bit of a scare myself when at Cape Tribulation. Emmagen Creek is just that, a small permanently-flowing creek with a few good swimming holes about two minutes walk from where we were camping. As was my wont, first thing of a morning I'd go to the creek to wash up and bush my teeth at its bank. One morning I sensed the presence of something nearby and to my right less than 18" away was a yellow-bellied black snake of a type I wasn't familiar with (like those I know from down south). Like me, it was hanging from bank and drinking the water (it seemed totally obvious to my presence). No worries, one keeps
perfectly still in those situations. When it finished drinking it just slid away.
Oh, that wasn't as nearly scary as when I accidentally stood on one of these critters close to where I lived as a kid (it was sunning itself on a bush path just around a bend that I couldn't see around): https://en.m.wikipedia.org/wiki/Eastern_brown_snake.
This is one truly nasty bugger that one doesn't want to mess with. I felt this squish under my foot, fortunately it took of at great speed in one direction and I did the fastest back-flip of my life in the opposite direction.
See, there are hazards here, but one usually survives.
