Australian households and businesses are navigating a complex energy landscape this July 2026, marked by a significant increase in fuel prices following the partial restoration of the federal excise, alongside a mixed bag of electricity bill adjustments. While many electricity customers on default offers are seeing modest reductions, the broader picture reveals ongoing volatility.

Fuel Excise Restoration Drives Petrol Price Surge

Motorists across Australia are feeling the pinch at the bowser, with the national average retail petrol price in the five largest cities rising by 18.1 cents per litre (cpl) by 15 July 2026, compared to 30 June. This increase follows the partial restoration of the federal fuel excise tax, which took effect on 1 July. The Australian Competition and Consumer Commission (ACCC) confirmed these movements in its 19th weekly fuel price monitoring report, published on 17 July 2026.

Diesel prices have also seen a notable jump. Weekly average Gasoil 10 ppm prices reached approximately 120 Australian cents per litre by 15 July, up roughly 13 per cent from the previous week. The ACCC’s report highlighted that average retail petrol prices in capital cities and most regional locations remained relatively stable over the last week of monitoring, but the impact of the excise restoration over two weeks has been substantial. These domestic price shifts are occurring against a backdrop of rising international benchmark prices for refined petrol (Mogas 95) and diesel (Gasoil 10 ppm), further exacerbating cost pressures for consumers.

Varied Electricity Bill Changes for July 2026

In contrast to the clear upward trend in fuel prices, electricity bills for many Australian households on default standing offers have seen more varied adjustments from 1 July 2026. The Australian Energy Regulator (AER) released its final Default Market Offer (DMO) determination for 2026-27 in May, which saw benchmark electricity prices fall for most residential and small business customers in New South Wales, South East Queensland, and for small businesses in South Australia. Victoria’s Essential Services Commission (ESC) also announced reductions for the Victorian Default Offer (VDO).

However, the actual impact on individual bills can differ significantly, as highlighted in various reports published in early to mid-July. For instance:

  • New South Wales: Residential flat-rate standing offer prices decreased between 3.4% and 5.0%, depending on the distribution area, potentially saving households between $66 and $137 annually.
  • South East Queensland: Households on flat-rate standing offers are experiencing a 7.2% price decrease, equating to annual savings of approximately $155.
  • South Australia: Flat-rate residential standing offers saw a modest 1.4% increase, making it the only DMO region with a rise for these customers. Conversely, time-of-use customers in SA saw a small decrease of 1.1%.
  • Victoria: Average household bills on the Victorian Default Offer are expected to decrease by 5%, translating to an annual saving of around $84.

“For most Australians, electricity prices are actually going down this July, not up. The Australian Energy Regulator (AER) confirmed its final decision on 26 May 2026, and benchmark electricity prices are falling in NSW, South East Queensland and South Australia. Victoria is also cutting prices. Western Australia is the one exception.”

Despite these reductions in benchmark prices, some retailers have adjusted their market offers and daily supply charges differently. Reports indicate that some customers, particularly in NSW and QLD, have seen significant increases in daily supply charges, which can offset some of the savings from lower usage rates, especially for those with low consumption.

The Rise of Solar Sharer Offers and Consumer Energy Resources

A significant new development from 1 July 2026 is the introduction of the Solar Sharer Offer (SSO). This opt-in plan requires retailers in DMO regions (NSW, SA, SE QLD) to provide eligible households with smart meters three hours of free electricity daily during peak solar generation periods. This initiative aims to encourage consumers to shift their energy use to capitalise on abundant midday solar power, supporting grid stability and potentially reducing individual bills. For example, the free period is typically 11 am to 2 pm in NSW and SE QLD, and 12 pm to 3 pm in SA.

The value of consumer energy resources (CER) such as rooftop solar, home batteries, and Virtual Power Plants (VPPs) in mitigating energy costs was further underscored by the ACCC’s June 2026 electricity market inquiry report, published on 10 July 2026. The report found that households participating in VPPs recorded some of the lowest electricity bills.

This highlights a growing trend where active engagement with renewable energy technologies and smart energy management can provide substantial financial benefits.

Future Energy Costs and Data Centre Obligations

Looking ahead, the Australian government is taking steps to manage future energy demand and costs. On 15 July 2026, Prime Minister Anthony Albanese announced new legal obligations for large-scale data centres. These facilities will be required to underwrite their own new clean energy supplies, pay full grid connection costs, and reduce power consumption when needed to strengthen the grid.

The policy aims to ensure that the burgeoning energy demands of data centres, particularly those driven by artificial intelligence, do not increase power prices for Australian homes and businesses. This proactive measure signals a commitment to integrating new, high-demand industries into the energy mix without burdening existing consumers. The legislation is expected to be introduced in early 2027.

For Australian energy consumers, July 2026 presents a mixed financial picture. While regulated electricity prices have offered some relief in most states, the increase in fuel costs is a direct hit to household budgets. The emergence of the Solar Sharer Offer provides a new avenue for savings for those with smart meters, and the proven benefits of home batteries and VPPs continue to offer a pathway to greater energy independence and lower bills. Understanding these diverse price movements and leveraging available programs will be crucial for managing household energy expenses in the coming months.
