The default market offer (DMO) is a government-set reference price for electricity in parts of Australia, designed to limit standing-offer prices and make plans easier to compare. Its cost varies by state or territory, distributor, tariff type and estimated household usage, and is usually shown as an annual estimate rather than a fixed bill amount. Your actual charges depend on your retailer’s plan, daily supply charge and electricity use. Check your bill’s reference price information and compare available offers through the government’s Energy Made Easy website.
