Australian households are navigating significant shifts in their electricity bills this July, following the annual reset of the Default Market Offer (DMO) by the Australian Energy Regulator (AER) and the Victorian Default Offer (VDO) by the Essential Services Commission (ESC). While many regions, particularly New South Wales and South East Queensland, are seeing notable reductions in benchmark electricity prices, South Australia faces a modest increase for flat-rate residential customers. Crucially, a new ‘Solar Sharer Offer’ has also launched, providing an innovative pathway for smart meter households to access free daytime electricity.
The AER’s final determination for DMO 8, effective from July 1, 2026, confirmed price falls for most households and all small businesses in New South Wales, South East Queensland, and South Australia. Similarly, Victoria’s ESC announced average reductions for both residential and small business customers. These changes are largely driven by a reduction in wholesale electricity costs, attributed to Australia’s ongoing build-out of renewable energy infrastructure, including wind and large-scale battery storage.
“This is a positive outcome with prices coming down for the majority of households and all small businesses across the three regions where the DMO safety net applies,” said AER Chair Clare Savage. “The reductions compared to last year reflect easing costs across most components of the DMO, particularly in wholesale energy, where we’ve seen lower electricity contract prices, reduced spot price volatility, and increased output from wind and battery generation during evening peaks.”
State-by-State Breakdown: July 2026 Price Changes
The impact of the DMO and VDO resets varies considerably across states and distribution zones. These figures represent changes to standing offers, which act as a price cap for customers who haven’t actively chosen a market offer.
| State/Region | Residential Flat Rate Change (Annual) | Residential TOU Change (Annual) | Small Business Flat Rate Change (Annual) | Small Business TOU Change (Annual) |
|---|---|---|---|---|
| New South Wales | Down 3.4% to 5.0% (saving $58-$226) | Down 3.7% to 7.7% | Down 9.0% to 11.3% (saving $432-$705) | Down 9.4% to 20.9% (saving up to $1,303) |
| South East Queensland | Down 7.2% (saving $155-$216) | Down 10.7% (saving $229) | Down 10.4% (saving $445) | Down 10.4% to 14.0% (saving up to $601) |
| South Australia | Up 1.4% (increase of $33) | Down 1.1% | Down 6.8% (saving $379) | Down 6.8% to 12.1% (saving up to $673) |
| Victoria | Down average 5% (saving $84) | New ‘Solar Soak’ tariffs introduced | Down average 6% (saving $241) | N/A (New TOU caps) |
| Regional Queensland | Down around 6.9% (saving $151 for Tariff 11) | N/A | N/A | N/A |
| Western Australia | Up 2.75% on daily supply charge | N/A | N/A | N/A |
It is important to note that while flat-rate residential customers in South Australia face a slight increase, those on time-of-use tariffs in SA will see a small reduction. Small businesses across all DMO regions are set to experience significant price drops.
The New Solar Sharer Offer: Free Midday Power for Smart Meter Homes
One of the most innovative additions from July 1, 2026, is the Solar Sharer Offer (SSO). This opt-in default offer is designed for eligible households with smart meters in DMO regions (NSW, South East Queensland, and South Australia). It provides three hours of free electricity daily during the peak solar generation period – typically 11 am to 2 pm in NSW and SE QLD, and 12 pm to 3 pm in SA.
The SSO has a daily cap of 24 kWh, which is sufficient to meet the needs of an average five-person household. Crucially, this offer is available to both homeowners and renters, even if they do not have their own rooftop solar panels. This initiative aims to encourage consumers to shift energy-intensive activities like running washing machines, dishwashers, or charging electric vehicles into the middle of the day, leveraging abundant and often low-cost solar energy.
Retailers with over 1,000 customers in DMO jurisdictions are now required to offer the SSO. The pricing outside the free window is regulated, mirroring the time-of-use DMO tariff, ensuring transparency and preventing excessive charges.
Why Your Bill Might Still Differ and What to Do
While the DMO and VDO determine the maximum prices for standing offers, the majority of Australian households are on competitive market offers. These market offers are set by individual retailers and may not always align perfectly with the default offer changes. Some reports indicate that while usage rates might fall, some retailers are increasing daily supply charges, which could impact low-usage customers.
This discrepancy underscores the importance of actively comparing electricity plans. The federal Energy Bill Relief Fund, which provided universal rebates, concluded on December 31, 2025, meaning households are no longer receiving automatic federal credits. What remains are state and territory-specific concessions for eligible groups.
Consumers are urged to review their current energy plans and compare them against new offers available in their area. Websites like Energy Made Easy (for NSW, QLD, SA, TAS, ACT) and Victorian Energy Compare are valuable tools for this. Choosing a more competitive market offer could still lead to significant annual savings, potentially hundreds of dollars beyond the default offer reductions.

Furthermore, understanding different tariff structures, such as Time-of-Use (TOU) and controlled load tariffs, can help households optimise their energy consumption. For those with smart meters, the Solar Sharer Offer presents a new opportunity to reduce bills by strategically shifting energy use.

The Role of Renewables and Future Outlook
The reduction in wholesale electricity costs is a direct result of increased renewable energy generation and battery storage capacity entering the National Electricity Market (NEM). As renewables now constitute over half of Australia’s national grid generation, their impact on lowering energy prices is becoming increasingly evident.
This shift highlights the ongoing transition of Australia’s energy landscape. While network charges, covering the poles and wires, have seen increases in some areas (e.g., Ausgrid NSW up ~10%, Energex SE QLD up ~12%), the overall downward pressure from wholesale costs has generally prevailed for default offers.
For households considering solar or battery storage, these price shifts, coupled with the new Solar Sharer Offer, reinforce the value of maximising self-consumption and leveraging peak solar generation periods. Exploring options like home batteries can further enhance savings, as detailed in our comprehensive resource on the Best Home Batteries in Australia 2026: Models, Costs & Up To $7,500 Rebates.
