where i live you can get it for 0.09 AUD for about 9 hours per day (10pm to 7am) which is an off-peak price.
during the other 15 hours of the day it's 0.22 AUD.
I thought you weren't able to connect anything but hot water systems to Off peak power? That doesn't make sense as EV's should recharge then, but that's what I'd heard.
