From 1 July 2026, most Australian households on Default Market Offer (DMO) or Victorian Default Offer (VDO) standing contracts will see price reductions. Residential flat rate DMOs in New South Wales will decrease by 3.4% to 5.0% (saving up to $137 annually), and in South East Queensland by 7.2% (saving $155 annually), while South Australian households will experience a modest 1.4% increase ($33 annually). Victorian households on the VDO will see an average reduction of 5%, equating to approximately $84 per year, with savings ranging from $50 to $160 depending on the distribution zone.
The universal Federal Energy Bill Relief Fund payments, which provided up to $300 for households and $150 for small businesses, concluded on 31 December 2025 and are no longer active for the 2026 calendar year. However, state-based schemes continue, such as the NSW Low Income Household Rebate (up to $200 annually), Victoria's Solar Homes Program offering rebates for panels and batteries, and the Federal Cheaper Home Batteries Program which transitioned to a tiered rebate structure from 1 May 2026.
To reduce electricity bills in 2026, actively compare market offers against the new DMO/VDO reference prices, as many market offers can provide greater savings than standing offers. Households with smart meters in DMO regions (NSW, SEQ, SA) can explore the new Solar Sharer Offer, providing three hours of free electricity daily, while Victorians can consider the Midday Power Saver from 1 October 2026. Additionally, leveraging state and federal solar and battery incentives, such as the Small-scale Renewable Energy Scheme (STCs) and various state-specific battery rebates, can significantly cut long-term energy costs.
