This sign is for a slide called "Free Fall" at Questacon in Canberra.What I'm wondering is why they think anyone with a fear of heights would close enough to a slide that involves a drop of several metres to read the sign.
Yes, Australia is a very dry continent and yes water is very precious, but "Water is like gold to us", come on. I once saw an Australian panning for gold and he left the gold and took the water home. No, not really.
