Mandurah locals receive the highest volume of parcels in the state.
New data from Australia Post has revealed the Peel region city received more parcels than any other suburb in 2025, followed by Success and Wanneroo.
Pinjarra, Maragret River, and West Busselton were the fastest growing suburbs for online shopping.
The annual eCommerce report also revealed Western Australian's spent $9.14 billion online last year, up 18 per cent on the previous year — the strongest growth of any state or territory.
West Australian millennials are the biggest online shoppers spending $3.46 billion, followed by Gen X ($2.57 billion) and Gen Z ($1.55 billion).
Despite 9.8 million Australian households shopping online last year, their individual basket sizes continue to shrink due to cost-of-living pressures.
The average basket size is now $96, down $10 from five years ago.
Australia Post Executive General Manager Parcel, Post & eCommerce Services, Gary Starr said despite smaller baskets, overall spend continues to climb which is largely driven by an increase in purchase frequency.
“On average, Australians purchased from 16 different online brands last year, a figure that has been growing for the past decade. As they shop more online, it’s how they shop that’s continuing to evolve," Mr Starr said.
"Australians are shopping smarter, they’re comparing more brands, buying more frequently and expecting a seamless experience from checkout through to delivery."
Australians spent the most on Online Marketplaces ($18.9 billion), Fashion and Apparel ($11.6 billion) and Home and Garden ($11.4 billion).
