As the Australian Energy Regulator’s (AER) new Default Market Offer (DMO) and the federal government’s innovative Solar Sharer Offer officially commenced on July 1, 2026, millions of households across New South Wales, South East Queensland, and South Australia are urged to critically review their electricity plans. While the DMO brings price reductions for many on standing offers, the AER and consumer advocates are reiterating a crucial message: remaining on a standing offer could still cost you hundreds of dollars more annually compared to competitive market offers.
This renewed call to action comes as customers begin to see the impact of the July 1st changes on their bills. The DMO, which acts as a price cap for residential and small business customers who haven’t actively chosen a market offer, is fundamentally a safety net, not necessarily the cheapest option available. Data from the AER indicates that market offers from retailers are often up to 20% below the DMO reference price.
The Cost of Inactivity: Why Standing Offers Lag
Approximately 8% of residential customers, or around 463,000 households, remain on standing offers across the DMO regions. These customers are automatically subject to the DMO rates. While the DMO for 2026-27 saw reductions for flat-rate standing offers in NSW (between 3.4% and 5.0%, or $66 to $137 annually) and South East Queensland (7.2%, or approximately $155 annually), South Australian residential flat-rate customers experienced a modest 1.4% increase, equating to about $33 per year.
However, the real concern for regulators is the significant disparity between these DMO-capped standing offers and the more competitive market offers available from various retailers. For customers who haven’t switched plans in over a year, the gap between their old standing offer and a new, more aggressive market offer could be substantial, potentially reaching up to $800 annually in savings. This figure represents the opportunity cost of not engaging with the market.
Adding to the complexity, some retailers have reportedly increased their fixed daily supply charges from July 1st. This means that even if per-kilowatt-hour usage rates decrease, households with lower overall energy consumption might still see their total bills rise due to higher fixed fees, offsetting any DMO-driven savings on usage.
“The DMO is not intended to be a competitive market offer — market offers from retailers are typically up to 20% below the DMO reference price.”
Solar Sharer Offer: A New Opportunity from July 1st
In tandem with the DMO adjustments, the federal government’s new Solar Sharer Offer (SSO) also became available from July 1, 2026, for eligible households in NSW, South East Queensland, and South Australia. This innovative opt-in scheme provides three hours of free electricity daily during peak solar generation times – typically 11 am to 2 pm in NSW and SE QLD, and 12 pm to 3 pm in SA.
The SSO is designed to encourage households to shift their energy consumption to periods when wholesale electricity prices are often at their lowest, or even negative, due to abundant solar generation. It’s available to residential customers with a smart meter, regardless of whether they have rooftop solar panels. There’s a daily cap of 24 kWh on the free electricity, which the AER considers ample for an average five-person household.
For those with smart meters, leveraging offers like the Solar Sharer can significantly impact annual bills. Understanding how to maximise these new tariff structures is key to unlocking further savings.

State-by-State DMO Changes (Residential Flat Rate Standing Offers from July 1, 2026):
| State | Change | Annual Impact (approx.) |
|---|---|---|
| New South Wales | -3.4% to -5.0% | -$66 to -$137 |
| South East QLD | -7.2% | -$155 |
| South Australia | +1.4% | +$33 |
Note: These figures are for typical residential flat-rate standing offers and vary by network zone. Time-of-use customers may see different impacts.
Victoria operates under its own Victorian Default Offer (VDO), which also saw average residential price reductions of 5% from July 1, 2026.
Act Now to Avoid Overpaying
The message from energy regulators and consumer groups is clear: the commencement of the new DMO and SSO on July 1st presents a prime opportunity for all Australians to review their energy plans. If you are on a standing offer, or haven’t compared plans in the last 12 months, you are likely paying more than necessary.
Comparing electricity plans is a straightforward process, often taking only minutes using independent government comparison websites like Energy Made Easy.

The Wider Market Context
The downward pressure on wholesale electricity prices, largely driven by Australia’s increasing renewable energy generation and battery storage capacity, is the primary factor enabling these DMO reductions. The Australian Energy Market Operator (AEMO) has noted that batteries are increasingly displacing more expensive gas and hydro generation during evening peaks, leading to flatter prices throughout the day. This evolving energy landscape means that actively engaging with the market and choosing plans that align with your consumption patterns is more crucial than ever to maximise savings.
While the initial DMO determinations were made in May, the July 1st implementation marks the point where these changes directly affect household bills, making a plan review an immediate priority for savvy consumers.
