Australian electricity consumers are set to experience varied changes to their power bills from July 1, 2026, as regulators in Victoria, New South Wales, South East Queensland, and South Australia finalise their annual default offer determinations. While many households and small businesses will see reductions, particularly in Victoria and Queensland, South Australian residential customers on default offers face a modest increase.
The Essential Services Commission (ESC) in Victoria and the Australian Energy Regulator (AER) for NSW, South East Queensland, and South Australia, released their final decisions in late May 2026, setting the benchmark prices for default or standing offer contracts for the 2026-27 financial year. These regulated prices serve as a safety net for customers who do not actively shop for market offers and act as a reference point for all retail energy plans.
Victoria Leads with Average 5% Household Drop
Victorian households on the Victorian Default Offer (VDO) will see their annual electricity bills decrease by an average of 5%, equating to approximately $84 in savings. Small businesses are set for even greater relief, with an average 6% reduction, saving around $241 annually.
This marks a positive shift for Victorians, driven primarily by a reduction in wholesale electricity costs, lower network charges, and decreased environmental scheme costs. The ESC confirmed its final decision on May 20, 2026, with the new rates commencing July 1, 2026.
“On average, households on the Victorian Default Offer will save $84 a year and small businesses on the offer will save $241 a year.”
The savings for residential customers will vary across the state’s five distribution zones, ranging from approximately $50 in the United Energy area to $160 in the AusNet services zone. Approximately 512,000 Victorian households and 62,000 small businesses are currently on these default contracts and will benefit directly from the price cuts.
For the first time, the ESC is also introducing a reference price for time-of-use (ToU) tariffs, offering greater transparency for consumers with smart meters who can manage their consumption during off-peak periods.
Mixed Fortunes for DMO States: QLD Sees Largest Time-of-Use Cut
The Australian Energy Regulator’s (AER) final Default Market Offer (DMO 8) determination, released on May 26, 2026, outlines varied outcomes for NSW, South East Queensland, and South Australia.
New South Wales (NSW) customers on flat rate standing offers can expect reductions between 3.4% (around $66 annually) and 5.0% (up to $137 annually), depending on their distribution zone (Ausgrid, Endeavour Energy, Essential Energy). Those with smart meters on time-of-use tariffs will see even larger drops, ranging from 3.7% (approximately $72) to 7.7% (up to $211). Small businesses in NSW are poised for significant savings, with reductions between $432 and $1,303 annually.
South East Queensland (SEQ) households in the Energex zone will benefit from a 7.2% reduction on flat rate standing offers, saving approximately $155 per year. The region also boasts the largest residential time-of-use (ToU) reduction nationally, with prices falling by 10.7%, translating to about $229 in annual savings for eligible customers. Small businesses in SEQ can anticipate reductions ranging from $445 to $601 annually.
South Australia (SA), however, presents a mixed outcome. Residential customers on flat rate standing offers will face a 1.4% increase, adding approximately $33 to their annual bills. Conversely, SA households with smart meters on time-of-use tariffs will see a modest 1.1% decrease, saving around $25 per year. Small businesses in SA will experience reductions between 6.8% ($379) and 12.1% ($673). The increase for SA residential flat rates is attributed to higher transmission costs that did not fall in line with other DMO regions.
Wholesale Costs and Renewables Drive Down Prices
The overall trend of falling default offer prices in most regions is largely attributed to easing wholesale electricity costs. Increased renewable energy generation, particularly from wind and solar, coupled with expanded battery storage capacity, has helped to reduce reliance on more expensive gas and pumped hydro during peak demand periods. This has contributed to greater market stability and lower spot prices.
New Solar Sharer Offer to Boost Savings
In a significant new development, the AER’s DMO 8 determination introduces the Solar Sharer Offer (SSO), available from July 1, 2026. This opt-in offer provides households with smart meters up to three hours of free electricity during midday solar peak hours, with a daily cap of 24 kWh. Crucially, the SSO is available even to homes without rooftop solar panels, including renters.
This initiative aims to help households reduce their power bills by shifting energy use to periods of abundant solar generation, while also supporting a more reliable and efficient grid.

Regional Queensland and Western Australia Updates
Outside the AER’s DMO regions, Regional Queensland (Ergon Energy zone) will also see price adjustments. The Queensland Competition Authority (QCA) announced that residential bills on Tariff 11 will decrease by 6.9%, saving approximately $151 annually. Small businesses on Tariff 20 will see an 8.1% decrease, equating to about $212 in annual savings. However, the solar feed-in tariff in regional Queensland will decrease from 8.660 cents per kWh to 6.006 cents per kWh, reflecting lower daytime wholesale costs.
In Western Australia, where electricity prices are regulated by the State Government, most households will experience an increase from July 1, 2026. The standard residential tariff (Synergy Home Plan A1) will rise by 2.75%. This includes an increase in the daily supply charge from 116.05c to 119.24c per day and the usage rate from 32.37c to 33.26c per kWh. Time-of-use tariffs are also set to increase. These increases are attributed to rising costs of generating electricity and maintaining network infrastructure.
What This Means for Your Bill
While default offer prices provide a benchmark, it’s important to remember that most Australian households and businesses are on market offers. These offers are typically more competitive than standing offers, often providing larger discounts. Customers on standing offers will see the changes automatically applied from July 1, 2026. However, even those on market offers should review their current plans. The downward pressure on wholesale prices and the introduction of new offers like the Solar Sharer Offer mean there could be further savings available by comparing plans.
