If you run an online store in Melbourne, the past twelve months probably felt harder than they should have. New research helps explain why. The PayPal 2026 eCommerce Index maps the Australian eCommerce trends shaping how the country shops online — and several of its headline findings run directly against what most business owners assume is happening. Almost everyone shops online now, yet they are spending less. The youngest, most digital shoppers spend the least of all. AI has quietly gone mainstream at the checkout. Below are seven findings from the report worth a place in your 2026 planning, and a plain read on what each one means for your business.
Australians shop more, but spend less
The latest online shopping statistics from Australia tell a two-sided story. Ninety-nine per cent of Australians now shop online and 63% do it weekly — near-universal adoption. But the average monthly online spend has fallen to $881, down 29% from $1,247 a year earlier. Even the big spenders are a minority — just 23% of Australians spend $1,000 or more online each month. Baskets are shrinking even as the habit deepens.
For your business, the takeaway is blunt: winning a customer’s attention is no longer the hard part. Winning a larger share of a tighter wallet is. Cost-of-living pressure is doing the talking, and it rewards stores that make the value obvious and the buying decision easy.
The “digital natives” spend the least
Here is a finding that upends a common assumption. Rank monthly online spend by generation and Gen Z sits at the bottom, not the top. Gen X spends the most at $1,040 a month, followed by Millennials at $948 and Boomers at $789. Gen Z trails at $630. They shop more often — 3.3 times a week against a 2.4 average — but in much smaller baskets.
If your marketing budget leans towards the youngest shoppers on the assumption that they carry the most spending power, these Australian eCommerce trends suggest a rethink. Frequency and value are not the same thing.
Smartphone-only shopping has more than tripled
Mobile has crossed a line. The share of Australians who shop exclusively on a smartphone has jumped to 24%, up from just 7% a year ago. Computer-only shopping has halved to 7%. Most people (61%) still move between devices, but the direction is unmistakable — the smartphone is now the single most preferred way to shop, named by 44% of Australians ahead of laptop (30%) and desktop (16%).
For a growing quarter of your customers, your website is your mobile site. If your checkout, product images or navigation only really work on a desktop, you are quietly turning buyers away. A mobile-first build is no longer a nice-to-have in Australian online retail.
Buy now, pay later is shrinking — which makes it a differentiator
Buy now, pay later has cooled. Usage has dropped to 26% of Australians, down 11 points from 37%, and only 19% of businesses still offer it, down from 27%. On the surface that reads like a reason to drop it. Look closer.
Fewer competitors offering buy now pay later in Australia means it now works as a genuine point of difference rather than table stakes. PayPal’s research found its Pay in 4 option lifted stated purchase likelihood by 79%. If your average order value and margins support it, a well-placed instalment option can set you apart precisely because so many stores have stepped back.
The security confidence gap
This is the trend most likely to be hiding in your blind spot. Businesses believe they are handling security well: 47% rate their own cybersecurity as “very good” on at least one measure. Their customers do not agree. Only 25% of consumers trust Australian businesses to keep their details safe, and 44% think businesses are not doing enough.
That gap between how secure you feel and how secure you look is a conversion problem, not just an IT one. Visible trust signals — recognised payment logos, clear security messaging and a checkout that feels safe — close the distance.
AI shopping is already mainstream — trust is the bottleneck
AI shopping is not a future trend; it is a current one. Nearly half of Australians (48%) have already used AI to help them shop, rising to 62% of Gen Z, for tasks like price comparisons, product comparisons and visual search. But adoption has outpaced trust. A striking 93% of shoppers hold at least one concern — fraud and data security (80%), biased recommendations (78%) and overspending (59%) among them — and only 44% trust AI product recommendations.
The opportunity is not to bolt AI onto everything. It is to use it where it genuinely helps and to be open about it, because trust is the one thing customers are still withholding.
Agentic commerce is a small-business risk
One finding deserves the attention of every smaller retailer. “Agentic commerce” — AI shopping agents that browse and buy on a customer’s behalf — is arriving, and 29% of businesses are already evaluating or preparing systems for it. The catch: 35% of businesses fear those agents will favour bigger or competitor brands.
If AI becomes a gatekeeper to discovery, the shops that structure their product data clearly and build genuine search authority are the ones agents will find and recommend. For a Melbourne SMB, preparing for AI-driven discovery is a competitive issue, not a technical afterthought.
What these Australian eCommerce trends mean for your business
Pulled together, the report points to a clear set of priorities for online businesses through 2026:
- Build mobile-first, not just mobile-friendly. With smartphone-only shopping tripling, the phone experience is now the main event.
- Make the value obvious. Baskets are smaller, so reduce friction and surface reviews, shipping terms and clear pricing early.
- Show that you are safe. Recognised payment logos and plain-English security messaging help close the trust gap customers feel.
- Treat BNPL as a differentiator. With fewer stores offering it, a well-placed instalment option can stand out.
- Get discoverable by AI. Structure your product data and content so both search engines and AI shopping agents can understand and recommend you.
None of this needs a wholesale rebuild. Most of it is about tightening what you already have — the checkout, the mobile experience, the trust signals and the way your content is structured.
