There's water crisis in Australia, but it's the amount of water that's the problem (currently going through a drought) and not the quality. Our water's fine; my science teacher warns us not to wash our hands in the taps, even if it's crystal clear, only because the stainless taps are old. Like 30 years old.
The taps are clean too. Only thing unclean around here is the local river... which is green. Most likely because it's full of algae...
