DMO 8 Explained: Electricity Prices Are Falling. Is Your Retailer Passing It On?

Good news: electricity prices are falling for most Australians from 1 July 2026. The Australian Energy Regulator handed down its final DMO 8 determination on 26 May 2026, and the numbers are a meaningful step down from last year.

The catch: whether you actually see that saving depends entirely on your retailer and your contract. For many households on market contracts, the cut won't arrive automatically. And alongside the price changes, a significant new tariff type has become mandatory — one that's particularly relevant if you have solar panels on your roof.

Here's what changed, who it affects, and what to do about it.

Figures from the AER's final DMO 8 determination, 26 May 2026. Verify your current rates with your retailer — market contract prices vary independently of the DMO.

What the DMO Actually Is

The Default Market Offer (DMO) is the AER's annual price determination for standing-offer residential customers in NSW, SE Queensland, South Australia, the ACT, and Tasmania. Think of it as a regulated price ceiling: retailers can't charge standing-offer customers more than the DMO rate.

Most Australians aren't actually on standing offers — they're on market contracts, which can be above or below the DMO. But the DMO matters because it anchors the entire market. It's the comparison reference point retailers are required to use on your bill and in their advertising.

Victoria operates separately, under the Victorian Default Offer (VDO) set by the Essential Services Commission — not the AER. More on that below.

What Changed Under DMO 8

After a difficult 2025–26 year — DMO 7 raised standing-offer prices by 8.3–9.7% in NSW, 2.3–3.2% in SA, and 0.5–3.7% in SE Queensland — DMO 8 reverses course.

From 1 July 2026:

• NSW: prices fall 3.4–5% depending on distributor network area
• SE Queensland: prices fall 7.2%
• South Australia: prices rise 1.4% (the exception — SA is moving in the opposite direction this year)
• ACT and Tasmania: also covered by DMO; check the AER's published determination for your specific area

For a typical NSW household paying around $1,500 a year, a 4% reduction is about $60 a year. Not transformative — but meaningful, and in the right direction after last year's increases.

In Victoria, the VDO 2026–27 saw approximately a 3% reduction, equivalent to around $46 a year for a typical household.

The Part Most People Miss

Here's where it gets important. If you're on a market contract — which most households are — your electricity price does not automatically drop when the DMO drops.

Market contracts are set by your retailer and governed by the terms of your specific agreement. Some retailers will pass through the reduction. Others may not. Your contract renewal terms, any conditional discounts you're on, and how your retailer prices their market offers all determine what you actually pay.

The DMO change is a moment to check, not a guarantee of savings.

If your bill arrived recently and you're still trying to work out whether you've benefited: look for a letter or email from your retailer about price changes, or check the Price Fact Sheet for your current plan on the AER's Energy Made Easy site.

The Solar Sharer — A New Mandatory Tariff

Alongside the price changes, DMO 8 introduces a requirement that affects every solar household in the NEM: from 1 July 2026, all retailers must offer a Solar Sharer tariff.

A Solar Sharer plan provides free or heavily discounted electricity during a three-hour midday window — the period when solar panels generate the most power and the grid is typically awash with rooftop solar. The idea is to give solar households a more favourable structure: instead of exporting cheap solar at a low feed-in rate and buying it back at a high peak rate later in the day, you can use electricity freely during peak solar hours.

Two things to understand clearly:

This is a retailer obligation to offer the tariff — it is not automatic. You will not be moved to a Solar Sharer plan without requesting it. You need to actively ask your retailer whether you're eligible and what the plan looks like for your usage profile.

Not every solar household will benefit. The value of a Solar Sharer plan depends on when you actually use electricity. If you're out during the day and your solar is mostly being exported anyway, a Solar Sharer may not add much. If you're home during the day, running appliances in the midday window, it could be significant.

What To Do Now

The DMO 8 determination is a natural check-in moment. Prices have moved. A new tariff type has arrived. The question is whether your current plan is still the best available for your household.

Three steps worth taking:

First, find your current tariff type and rate. Look for the Price Fact Sheet on your latest bill or on your retailer's website. Note your usage rate (c/kWh) and supply charge ($/day).

Second, check whether your retailer has communicated any changes from 1 July. If they haven't, contact them and ask what's happening to your plan from that date.

Third, run a comparison. The AER's Energy Made Easy (energymadeeasy.gov.au) is free and covers the full market for NSW, SE QLD, SA, ACT, and TAS. Victoria has its own tool at compare.energy.vic.gov.au. Or use our lazy-tax check below to get a quick estimate of whether your plan is still competitive.
