Shopify has revealed what Australian shoppers were obsessing over in January.

The platform’s sales data reflects Australian merchant transactions last month compared to December 2025.

The Australian Open

Tennis ball sales skyrocketed (up 1060.2%) as the Australian Open took over Melbourne Park, marking them as the highest trending product category in Australia for January.

This momentum extended beyond tennis balls, with visors (up 153.4%) and tennis racket accessories (up 29.3%), and field and court boundary markers (up 33.7%) also seeing growth.

Fitness more broadly remained high on resolution lists, adds Shopify, with suspension handles and straps (up 181.9%) surging as Australians invest in strength training.

Cardio machine accessories (up 46%), balance cushions (up 33%) and dancing shoes (up 52.4%) also stepped up in January.

Back to school

January marked a strong return to routine. Pocket folders (up 462.1%) saw one of the biggest spikes across all categories as students and professionals embraced organisation for the year ahead.

School uniforms (up 219.6%) flew off the shelves, while lunch boxes and totes (up 102%) jumped as families prepared for the return to classrooms.

A health reset

Australians are clearly prioritising personal care in the new year, according to Shopify.

Oral health products saw standout growth, with mouthwash (up 145.4%), dental floss (up 143.4%) and toothpaste (up 74.7%) all rising month on month as shoppers prioritised white teeth.

Feet care saw growth, too, with arch supports (up 62.8%) and corn and callus care supplies (up 34.3%) seeing a rise. 

Other health tech and performance-focused products also trended upwards, from completely-in-canal hearing aids (up 62.7%) to nutrition gels and chews (up 40.2%), nutrition drinks and shakes (up 24.4%) and blood pressure monitors (up 23.9%).

Household refresh

The reset extended beyond routines and fitness, says Shopify.

Plant and flower bulbs (up 115.8%) bloomed in popularity as Australians refreshed their outdoor spaces for the year ahead.

Inside the home, practical upgrades dominated. Hand towels (up 94.4%), food container covers (up 75.3%), insulated bags (up 65.7%) and twist ties and bag clips (up 46.7%) all saw strong month on month growth.
