The new age of E-Commerce: Key factors that will drive sustainable growth

Australia’s e-commerce landscape has undergone rapid transformation, moving from early adoption to everyday habit.

In Aden Advisory’s 2025 National E-Commerce Outlook, new data from thousands of online shoppers reveal how convenience, speed, and experience are reshaping expectations—and where brands must evolve to keep up. As online retail now accounts for 17.4% of total retail sales (up from 11.2% in 2020), the next phase of growth will be defined not by access, but by execution.

 

Packages at the Door

Convenience remains the single biggest driver, cited by 76% of consumers as their top reason for shopping online—especially among full-time workers and parents. Mobile usage has taken over as the default: more than 61% of all online purchases are now made via smartphones, highlighting the critical role of mobile-first design and app-based engagement.
 

Beyond convenience, other key motivators include variety (63%), instant price comparison (51%), personalized shopping journeys (46%), and faster fulfillment (44%). Shoppers are not just browsing—they’re benchmarking, curating, and expecting delivery within days, if not hours.
 

However, the online shopping experience is still far from seamless. Nearly half (49%) of consumers report frustration with delivery delays, while 32% cite unclear or restrictive return policies as a reason to abandon a purchase. Unexpected shipping fees are another sticking point, with 27% of shoppers admitting to abandoning their cart when costs appear late in the checkout process. Among those who experienced delivery delays over five days, 61% said they were unlikely to repurchase from the same retailer.
 

The rise of mobile commerce is accelerating these expectations. Gen Z and Millennials are 2.5 times more likely to complete purchases via mobile apps, and mobile-exclusive flash sales drive conversion rates up by 17%. With 80% smartphone penetration in Australia, retailers must prioritize responsive, frictionless mobile experiences to stay competitive.
 

Different generations bring different behaviors to the e-commerce table. Gen Z is influenced by TikTok ads, social commerce, and user reviews—mobile-native and fluid in brand loyalty. Millennials remain price-conscious but reward sustainability and loyalty programs. Gen X focuses on reliability and delivery guarantees, while Boomers are growing users of voice search and click-and-collect services.
 

User experience has become the linchpin of conversion. One in three users abandons checkout due to slow-loading pages or confusing design. Features like auto-fill and one-click checkout boost conversions by 21%, and live chat integrations drive a 12% higher post-purchase satisfaction score. Seamless UX is no longer a luxury—it’s a necessity.
 

Subscription models are also gaining traction. In categories like health, pet care, and skincare, over 29% of consumers now subscribe to at least one product or service. They value convenience, predictable delivery, and discounts for recurring orders. These models reduce shopping friction and create stickier customer relationships.
 

Returns remain a major hurdle. Forty-two percent of online shoppers say unclear return policies deter them from trying new brands. Retailers that offer free returns, instant refunds, and flexible drop-off options report up to 35% higher retention metrics. As online competition intensifies, removing post-purchase friction is essential to long-term loyalty.
 

Environmental concerns are also shaping purchase decisions. Nearly half of consumers (48%) prefer retailers offering carbon-neutral delivery options, and 33% are willing to wait longer for eco-friendly shipping. Packaging waste, in particular, is a growing concern—especially among Gen Z and younger Millennials.
 

To remain competitive, retailers must focus on five strategic priorities:

  • Invest in Last-Mile Logistics: Delivery speed and reliability are critical to differentiation.

  • Simplify Returns: Clear, flexible return policies build trust and reduce barriers to trial.

  • Optimize for Mobile: Responsive mobile design and app-based perks drive engagement.

  • Embrace Personalization: Dynamic recommendations and tailored experiences improve basket size.

  • Integrate Sustainability Messaging: Environmental values resonate deeply with younger buyers.
     

Looking ahead, technologies like AI-powered personalization, social commerce, and augmented reality will redefine the e-commerce experience. Brands that combine innovation with empathy, transparency, and seamless execution will lead the next chapter of digital retail.
