Cairns homes can use more electricity for air conditioning, pool pumps and hot-water systems, particularly during hot or humid weather. Check your bill against previous usage in kilowatt-hours, confirm the meter read is actual rather than estimated, and review your retailer’s tariff and supply charges. Simple steps such as raising the air-conditioner setting, cleaning filters and using appliances outside peak periods may help, depending on your plan. Compare available offers through the Australian Energy Regulator’s Energy Made Easy website, and contact your retailer if the bill seems incorrect or you need a payment arrangement.
