Queensland Energy Affordability Bill 2026 to Limit Electricity Price Rises for Cairns Households
Cairns residents using air conditioning through the wet season will face capped annual price increases under the new state legislation that takes effect in October.
How we reported this
The Queensland Energy Affordability Bill 2026 received royal assent on 3 July and introduces a 3 per cent annual cap on regulated electricity tariffs for households in regional postcodes north of Mackay. The measure applies to customers of Ergon Energy, which supplies most of far north Queensland including Cairns.
Why the legislation was introduced now
State treasury documents tabled with the bill cite the Productivity Commission report on household energy costs released in May 2026. The report identified that tropical climate zones experience above-average summer demand. The legislation states that the cap will remain in place for three years and will be reviewed by the Queensland Competition Authority each December.
Cairns households typically face higher consumption from cooling equipment between November and March. Local advocates note that many tourism and agriculture workers are employed on casual or seasonal contracts, making quarterly bill fluctuations difficult to absorb.
Direct effects on household budgets
A single-person unit in Cairns suburbs such as Manunda or Earlville can expect the regulated component of its bill to rise by no more than the prescribed percentage each July. Families with pool pumps or multiple split-system units will see the same percentage limit applied to the usage charge. The bill also extends an existing $120 annual rebate for concession card holders living in postcodes 4870 to 4879.
The explanatory memorandum attached to the legislation projects that the cap will reduce the average annual outlay for a Cairns household by between $85 and $140 compared with uncapped tariff paths. These figures are calculated from 2025 consumption data held by the Australian Energy Regulator.
Implementation begins on 1 October 2026. Ergon Energy must publish updated tariff schedules by 15 September. The Queensland Competition Authority will publish its first compliance report in December 2026, covering the initial three months of operation.
