Australian electricity and gas retailers including AGL, Origin Energy, EnergyAustralia, and Alinta Energy — offering household and business energy plans across the National Electricity Market, regulated by the AER.
The Big Three energy retailers — AGL, Origin Energy, and EnergyAustralia — supply the majority of Australian households with electricity and natural gas. All operate websites with online account management, usage tracking, and plan comparison tools.
Smaller and challenger retailers including Alinta Energy, Lumo Energy, and Red Energy compete on price, with many offering no-lock-in plans and guaranteed savings for customers switching from incumbents.
