re "good beer can be made from bad tasting water"

Trust me.

I was taking liberties with the "bad tasting" bit - really was only referring to "fresh" water (as opposed to salty water) with relatively high content of dissolved salts. Good beer is often a product of "hard" water and, in particular, that with an elevated content of calcium - like that in Adelaide (and some parts of Perth where the supply comes from calcium rich groundwater).
