Electricity prices in Cairns depend on your tariff, daily supply charge, household usage, controlled-load equipment and whether you receive a solar feed-in credit or concession. Many Cairns properties are in Ergon Energy’s regional Queensland service area, where available tariffs and market offers can differ from those in south-east Queensland. Compare the estimated annual cost, not just the usage rate, using the Australian Government’s Energy Made Easy website and check your latest bill for your current tariff. The retailer ultimately confirms the price and whether its offer suits your address.
