How we worked this out
South East Queensland saw the largest fall in the country from 1 July 2026, down 7.2%. These figures cover the Energex network in the south east, where the retail market is competitive. Regional Queensland is supplied by Ergon Energy on a separate regulated tariff with no retail competition.
Typical bills use average single-rate residential rates for 2026–27 (effective 1 July 2026), from the AER Default Market Offer and ESC Victorian Default Offer determinations, reviewed 20 July 2026. Cheapest plan figures come from live retailer plan data published under the Consumer Data Right, refreshed weekly. Your bill depends on your retailer, tariff type, meter and usage pattern. This is a guide, not a quote.

Our take on electricity in Mackay
Ergon is the sole retailer. Tariff optimisation is the main path to savings. Mining shift workers on time-of-use tariffs can save significantly by running appliances during daytime off-peak.
