General enquiries - Default Market Offer


The Default Market Offer (DMO) came into effect on 1 July 2019. The DMO is a new rule that limits the price that retailers can charge electricity customers on default contracts, known as standing offer contracts.

The AER’s role is to determine the maximum price that a retailer can charge a standing offer customer each year. 

It applies to small business and residential customers on flat rate tariffs in areas where there is no other retail price regulation – South Australia, New South Wales and south-east Queensland.

The DMO price for each area also acts as a ‘reference price’ for residential and small business offers in that area. When advertising or promoting offer pricing, retailers must show the price of their offer in comparison to the DMO/reference price. This aims to help customers more simply compare the price of different offers.

On 19 September 2019, we published our Position Paper as the first step in our process to determine the maximum DMO price for standing offer customers for the 2020-21 year.

The Competition and Consumer (Industry Code – Electricity Retail) Regulations 2019 (Regulations) sets out the legislative framework for the DMO.
