Two big-three retailers, compared fairly
<a href="/retailers/agl">AGL</a> and <a href="/retailers/energyaustralia">EnergyAustralia</a> are both members of Australia’s "big three", both retail electricity and gas nationally, and both price their market offers against the government reference price. That shared scale means they compete directly — but it does not make their prices identical. They differ in how they balance the daily supply charge against the usage rate, in whether discounts are guaranteed or conditional, in sign-up credits, and in what they pay for exported solar.
As with every retailer pairing, the honest verdict is "it depends". AGL may be cheaper for one household and EnergyAustralia for another in the same street, purely because of different usage patterns, and the answer can change when either updates its offers. The point of comparing them is not to crown a permanent winner but to find which one is cheaper for your bill, right now.
What to actually compare
Look at the daily supply charge and usage rate together. If you use little power, the fixed supply charge is the bigger share of your bill and the retailer with the lower daily charge tends to win; if you use a lot, the usage rate carries more weight. Then examine the discount: a headline pay-on-time (conditional) discount is only worth its face value if every bill is paid by the due date, whereas a guaranteed discount always lands.
Solar households should weigh the feed-in tariff, which can offset a higher usage rate. And check the benefit period on each plan plus the rates it reverts to — both retailers use time-limited offers, so today’s cheapest plan can quietly become expensive in a year. Comparing these specific fields, rather than the brand, is what tells you which retailer wins.
Who each genuinely suits
AGL suits households that want a large, established retailer with a wide plan range, solar and battery products, and app-based management, plus the option to bundle gas. EnergyAustralia suits people who want the same national reliability and dual fuel, and who prefer its particular plan mix, which at times includes fixed-rate or bill-smoothing options that appeal to households wanting predictability. Both are solid mainstream choices rather than niche specialists.
Because both refresh their offers regularly, neither holds a lasting price advantage. The cheaper of the two shifts with your usage, your network area and the calendar. So treat any blanket "AGL beats EnergyAustralia" claim with caution — it is only ever true for a particular household at a particular moment.
Let your bill decide
EnergySorted removes the guesswork. Upload a recent bill and it costs every AGL and EnergyAustralia plan against your real peak, off-peak and shoulder usage, your solar export and your gas steps, ranks them cheapest-first alongside the rest of the AER-listed market, and proves the result against your current bill in real dollars.
It takes no retailer commissions — you pay a small subscription (around $39 a year), so neither retailer can buy a higher spot — and it re-checks nightly, flagging the moment a benefit period ends or a cheaper plan appears.
