The Default Market Offer (DMO) is a government-set electricity price cap and reference price for households in New South Wales, South Australia and south-east Queensland. It limits what retailers can charge customers on certain standing offers, but it is not necessarily the cheapest available plan. Retailers use the DMO as a reference when displaying discounts, helping you compare offers more consistently. Your actual bill depends on your usage, location and retailer; compare plans through Energy Made Easy, or Victorian Energy Compare if you live in Victoria.
