Pacific Hydro has some nice and easy to understand pricing and great offers for Victorians see energythatcould.com.au/energy-plans/pricing-fact-sheets/
Red Energy redenergy.com.au/epis/quoteUi/ also has some good pricing, the peak/ off-peak option is probably best avoided as peak time is defined as 7am to 11pm. Unless you are nocturnal this is unlikely to suit when you are actually awake and needing to use electricity.
