Any tips/links appreciated, or if anyone knows where pre-coated glass can be obtained from in Australia let me know.
No matter how you might manage to get conductive traces onto the glass
substrate there is a slight problem when trying to make connections to
items which require soldering. In my experience glass doesn't take too
kindly to sudden and localised heating as you would get from a
soldering iron.
I've never managed to damage it that way, OTOH could always use a reflow oven, or hot air.

IIRC I've see spade lugs soldered to rear window demisters.

Then there is the problem if you need holes in the
glass...
the mirror guys know how to do that, and I've seem the windscreen repairers do small holes.

You seem to have it all sorted out, go for it!

Specialised glass - no doubt with pre-cut shape & size (bugger! I
should have made that a bit smaller, now it won't fit the case)
Specialised technique for applying conductive material.
Specialised techniques for attaching connections.
Specialised hole drilling.

All in all, just the sort of facilities one would have available in a
small scale electronics production workshop.

Oh, did you say you would get these things done by outside
contractors?

I wonder how interested a company would be (ie. one which might have
similar facilities to those which make car windscreens with heated
wiring and connectors attached) would be in your project. "Sure, we
can rejig our equipment which is set up to make windscreens to
manufacture your non-standard clear glass circuit mounting substrate -
how many millions do you want?"

Bye.

Maybe a borosilicate glass (pyrex) that's silvered and then etched?
Or more likely have copper evapourated onto it as a mirror.
Won't carry much current in the traces but maybe OK low low frequency cmos
