Not overly unusual. This is one reason why there is a track patrol before every single train movement on the kuranda range.
Would there be many tourists in the area with the cyclone and the rain as it is?
The Australian and International travelling public tend to have a pretty poor concept of what the Northern Wet Season is and what it entails. I doubt travel agents try to dissuade holiday makers either. There's still plenty of tourists up here regardless of the time of year, although the Winter months are usually the peak period. Cairns sees more than 3-million visits per annum.
