Here is an Australian centipede, the Orange-footed Centipede Cormocephalus aurantipes which I photographed in Morwell National Park, near here. This one is not as big, only growing to about 2.5 inches. I don't know whether this one has a nasty bite or not. I have seen quite a lot of them and have never been troubled by them.
Ooooo I've got you all beat. LOL Here in Israel we've got this long pure black centipede that I've seen sometimes more than 5 inches long. They are often seen around my kids' preschool, so when school starts, I'll see if I can get a photo.
