The default market offer (DMO) is a type of energy pricing set by the Australian Energy Regulator (AER) to ensure fair prices for consumers in the electricity market. It acts as a safety net, providing a baseline price for those who haven’t switched to a different plan or retailer. The DMO aims to protect customers, particularly those in vulnerable situations, from being overcharged. If you’re unsure if you're on a DMO or want to explore your options, it’s a good idea to check with your energy retailer or visit the AER's website for more details.
