On rentals: Anecdata vs ABS statistics. No one is arguing that rents haven't gone up, but the rise peaked post COVID at ~8% and are now roughly reverted to the mean of 3-4% pa.
On smart meters:
Victoria has had them for 2 decades now.
If there were anti-consumer uses that our retailers or distributers took advantage of we'd know about them by now.
We've also had a fully privatized grid for quarter of a century, with generators, transmission, distribution, and retail separated.
The rorts have been by the distributors "gold plating" the poles/wires, and some machinations of the NEM by coal/gas generators.
Neither of which were caused by the smart meter rollout.
