Trespassers, beware

A few weeks back, Roger Henry posted this to one of the mailing lists I'm still gettting caught up on reading:

In tropical, North Queensland, the Barron River plunges over an escarpment (See http://en.wikipedia.org/wiki/Barron_Falls ) A diversionary weir sends most of the water off to a hydro-plant and only a trickle tumbles down the rocks. Being more of a slope than a cliff the rocks are very tempting to rock-climbers, despite numerous warnings that operation of the power plant may, without notice, cause water to be restored to the falls. A siren alerts people that this is about to happen.

I asked a tour guide about the siren and if it was to give any climbers time to escape.

"No" he laughed "The water would arrive in a minute or two and climbers would not be able to get clear. The purpose of the siren is to give tourists a chance to prepare their cameras"

"And the climbers?" I enquired.

"Ahh. They would be swept away and certainly killed. No concern of ours. There are warning signs everywhere. The climbers have to get over a fence and trespass. Up to the police and relatives if they want to search for bodies".

That was many years ago™. Doubt if such candor would be PC today.
