Found an old link from my work that seems to be updated with new offers, I don't know if these represent good value but in NSW Alinta's rates seem pretty good. You can do it all online so no proof required for "Cricket Aus". I signed up previously to a 30% off deal and the process to change has been easy.
YMMV
NSW - https://www.alintaenergy.com.au/nsw/cricketaus
VIC - https://www.alintaenergy.com.au/vic-family-friends
SA - https://alintaenergy.com.au/sa-family-friends
seems to be usage only.
so what is the final price? is this actually a bargain?
