TDS at my tap in Willy is 81 ppm this morning, very close to previous values (it's been 78 - 80 the last few months).

 

There's no room for a significant lift in mineral content with a TDS of 80.

Not sure if Willy is short for Williamstown, but if so you would be using different water to me in Preston.

I doubt that the TDS is significantly different from yours. I can test yours if you don't believe this.

 

BTW Melbourne water deliberately raises the pH of the water supply for various reasons*, usually by calcification (liming). Maybe this was offline for a bit. If so the mineral content will have gone down, not up.

 

 

* Partly to counteract the acidification caused by chlorination and flouridation, partly to reduce corrosion on old pipework.

I also believe the merri region still has many open waterways and is therefore subjected to higher than "usual" treatment at times.  I remember a picture of one of those water ways with bags of rubbish that had been thrown in.
