Yep, brissy tap water is ok, but you will make a better beer with some simple things,
I fill my gf's up the day before or at least several hrs before mashin to allow my mineral additions to dissolve properly,
I run my tap water slowly through one of those cheap carbon inline caravan filters, I then treat my gf with half campden tab, and the sparge water urn with half a tab crushed and stired up well.
If doing hoppy type beers, I dissolve 10 grms of calcium sulphate, 2 grms of magnesium, 4 grms of calcium chloride, into my batch.
If doing lagers or English bitters etc, I use 6 grms calcium sulphate, 2 grms calcium chloride.
These might not be perfect but gets me close. Good enough and since doing this have noticed a nice improvement to my brews.
