Australian households and small businesses are navigating a varied landscape of electricity price changes this July, following the implementation of new Default Market Offer (DMO) and Victorian Default Offer (VDO) determinations. While many in New South Wales, South East Queensland, and Victoria will see their annual bills decrease, some in South Australia and the ACT face modest increases. A significant new development is the rollout of the ‘Solar Sharer Offer’, providing three hours of free midday electricity to eligible smart meter customers in DMO regions.
These price adjustments, announced by the Australian Energy Regulator (AER) and the Essential Services Commission (ESC) in late May and early June 2026, took effect on 1 July 2026. They reflect a complex interplay of falling wholesale electricity costs, largely driven by increased renewable energy generation, alongside rising network charges and other regulatory costs in specific areas.
Default Market Offer Delivers Mixed Outcomes
The AER’s DMO 8 determination applies to residential and small business customers on standing offers in New South Wales, South East Queensland, and South Australia. For the majority, this means a reduction in benchmark prices.
In New South Wales, residential flat-rate standing offer prices are projected to fall between 3.4% and 5.0%, equating to annual savings of approximately $66 to $137. Time-of-use customers in NSW could see even larger reductions, ranging from 3.7% to 7.7%, or up to $211 annually.
South East Queensland customers are experiencing some of the most substantial relief. Residential flat-rate standing offers have dropped by 7.2%, saving a typical household around $155 per year. For those on time-of-use tariffs, the reduction is even greater, at up to 10.7%, translating to annual savings of approximately $229.
However, the outlook is not uniform. South Australia residential flat-rate standing offer customers will see a slight increase of 1.4%, adding about $33 to their annual bills. This rise is attributed to wholesale and network costs not falling in the same manner as other regions. Despite this, South Australian time-of-use customers will still benefit from a 1.1% decrease, saving around $25 annually.
Small businesses across all DMO regions are generally receiving more significant reductions, with price drops ranging from 6.8% to 20.9% depending on their location and tariff type.
Victoria and Regional Queensland See Reductions
Victoria, which operates under its own Essential Services Commission (ESC) and the Victorian Default Offer (VDO), has also seen price reductions. From 1 July 2026, the VDO has decreased by an average of 5% for residential customers, saving a typical household approximately $84 per year. Small businesses in Victoria will see an average reduction of 6%, or about $241 annually.
In regional Queensland, regulated electricity prices, set by the Queensland Competition Authority (QCA), have also fallen. Households on Tariff 11 can expect to save around $151 per year, representing a 6.9% decrease. Small businesses in regional Queensland will see reductions of over 8%.
ACT Households Face Modest Increase
In contrast to many other states, the ACT’s regulated standing offer tariffs for ActewAGL customers have increased by an average of 2.7% from 1 July 2026. This translates to an annual bill increase of approximately $64 for an average residential customer consuming 6,500 kilowatt-hours (kWh) per year. The ACT’s economic regulator noted that while wholesale electricity purchase costs decreased, these savings were offset by a 15% increase in network costs and a 90% rise in costs associated with government large-scale feed-in tariff schemes.
“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,” AER Chair Clare Savage said regarding the DMO 8 determination.
Solar Sharer Offer: Free Midday Power
A notable addition to the energy landscape is the new Solar Sharer Offer, introduced as part of the DMO reforms. This innovative scheme provides eligible households with smart meters in NSW, South Australia, and South East Queensland three hours of free electricity every day during the midday solar peak.
The offer, typically running from 11:00 AM to 2:00 PM in NSW and SE QLD, and 12:00 PM to 3:00 PM in SA, includes a daily usage cap of 24 kWh. This is designed to encourage consumption when solar generation is abundant, helping to balance the grid and potentially reduce bills for customers, even those without their own solar panels. Renters with smart meters are also eligible.
This initiative presents a new opportunity for households to actively manage their energy consumption and reduce costs by shifting high-demand activities like running washing machines, dishwashers, or charging electric vehicles and home batteries to these free periods.

Understanding the Underlying Drivers
The primary driver behind the overall downward trend in electricity prices across most regions is a significant reduction in wholesale electricity costs. This is largely due to the rapid expansion of renewable energy generation, particularly solar and wind, coupled with increased grid-scale battery storage. This influx of cheaper, cleaner energy has reduced reliance on more expensive gas and coal-fired generation, especially during peak demand periods.
Conversely, rising network costs, which cover the maintenance and upgrade of poles and wires, continue to exert upward pressure on bills in some areas. The increase in ACT prices, for instance, was primarily offset by a 15% rise in network costs.

It is crucial for consumers to remember that the DMO and VDO represent a safety net – the maximum price a retailer can charge for standing offers. Competitive market offers from retailers are often priced significantly below these benchmarks. Therefore, actively comparing and switching electricity plans remains the most effective way for households and small businesses to secure the best possible energy deal and maximise savings in this dynamic market.

What This Means for Your Energy Bill
While the overall trend is positive for many, the variations mean that reviewing your specific energy plan is more important than ever. If you are on a standing offer in NSW, SE QLD, or Victoria, your bill should automatically reflect the new lower prices. However, if you are on a market offer, your rates are governed by your contract terms and may not change automatically. For those in South Australia on flat rates or in the ACT, understanding the reasons behind the increases and actively seeking competitive market offers is crucial to mitigate rising costs.
