The Default Market Offer (DMO) is a government-set benchmark and maximum price for certain electricity standing offers in New South Wales, south-east Queensland and South Australia. It gives households a reference bill based on typical usage, but your actual bill depends on your retailer, plan, location and electricity use. Market offers can be cheaper or more expensive than the DMO, so compare the estimated annual cost, usage rates and supply charges rather than assuming the DMO is the best deal. Victoria uses a similar benchmark called the Victorian Default Offer, while other states and territories have different arrangements.
