Commercial Solar PV of >100Kw Capacity

The STC rebate cap for solar PV under the SRES has been bumped up from 100kW to 1MW, which is a pretty massive jump.

The DCCEEW page says

The expanded SRES is expected to commence from 1 October 2026, subject to the necessary regulations being in place.

Anyone know if the regulations have actually been sorted yet, or is this still up in the air?

I’ve got a good quote in hand from a local installer and trying to figure out whether I should just sign now or hold off and wait for the regulations to actually come through first.
