New research from Mandala Partners and Amazon Australia shows online retail is saving the average Australian household $1,414 in 2026, the equivalent of six weeks of groceries. The data makes a cost-of-living argument for e-commerce that beats any tagline.
Online retail isn't just competing with physical stores. It's competing with inflation.
The second edition of the Surf, Shop, Save report was released on 27 May at Parliament House in Canberra. Produced by Mandala Partners and commissioned by Amazon Australia, it analysed the prices of more than 95,000 products sold through online channels and compared them against equivalent categories tracked in the Consumer Price Index. The headline figure is $1,414 in annual household savings from the competitive and efficiency effects of online retail.
What online retail competition saves the average Australian household in 2026, equivalent to six weeks of groceries
The number comes from two trends running in opposite directions. Since 2019, the Online Channel Index developed by Mandala Partners has deflated by 6 percentage points. Over the same period, CPI for comparable product categories has risen by 8 percentage points. The gap between what Australians pay online and what they pay in-store for similar products is now 14 percentage points.
The macroeconomic impact is not marginal. The report estimates that online retail reduced annual inflation by 0.8 percentage points in the year to March. In an environment where cost-of-living pressure is a top political and consumer concern, that's a structural deflationary force with a number attached.
Lower-income households benefit most in relative terms. As a share of household income, the savings are proportionally higher for households spending a larger fraction of income on consumer goods. That changes the social framing of e-commerce from a convenience layer to a cost-of-living relief mechanism.
For marketers in retail and e-commerce, the data point is an argument that has been sitting in plain sight. The value proposition of online channels has usually been pitched around range, convenience and speed. This research puts a dollar figure on the competitive pricing effect. For a consumer stretched on cost of living, $1,414 a year is more legible than "best price guarantee".
Amazon commissioning this research is not neutral. The report creates a political narrative, timed for Parliament House, that frames Amazon's scale as a public benefit. That framing will enter policy conversations around competition and retail regulation. Whether the methodology holds up to independent scrutiny matters, but right now the $1,414 figure is in the news cycle and it's the number that will stick.
