Greetings from SA (South Australia, not South Africa). Good shots of the koala. The last animal appears to be an echidna, or spiny ant-eater. We see them in my area. Running over them can ruin a car tyre, and its not much good for the echidna either!
An interesting shot. You have done well in what was probably difficult lighting. However, the picture leaves me wondering what used to drive the drill in the foreground. Obviously a belt drive from something, but what?
