Comparing my energy usage in Victoria (Jemena) and 1st Energy comes up on top. Hopefully, this is helpful for others.
Discounts:
Unconditional (15%): Percentage of usage
15% guaranteed discount off the market contract usage rates set out below.
A $275 credit, which will be applied to your next bill issued after 11 months of being billed by 1st Energy. The $275 credit will be applied every 12 months thereafter. Your entitlement to the credit is withdrawn if you transfer to a new retailer prior to the initial 11 months of billing or prior to the anniversary date every 12 months thereafter.
You are doing it so wrong if you stick with the same energy provider for 12 months without comparing price.
I compare price regularly every six months or so. I can always find something cheaper everytime. Don't pay the loyalty tax.
