Aussies Are Opening Their Wallets for AI: A Subscription Boom
More and more Australians are discovering the tangible benefits of artificial intelligence, to the point where they’re not just using it, but actively paying for premium AI services. Recent analysis of a staggering 8.3 billion Westpac customer transactions paints a clear picture: AI subscriptions are no longer a niche interest, but a rapidly growing segment of consumer spending.
In March alone, over 150,000 Westpac retail customers shelled out for at least one AI subscription, averaging a monthly spend of $37 per user. This figure represents a dramatic surge, a nearly 14-fold increase from the mere 11,000 Australians who subscribed to AI services in March of the previous year. This also marks a substantial 145 per cent jump in paid AI usage compared to the same period a year prior.
The Accelerating Pace of AI Adoption
Dan Jermyn, Westpac’s Chief AI Officer, highlighted the exponential growth trajectory. “Year-on-year, the pick-up is accelerating, not just progressing at the same rate,” he stated. “So I think we’re really just at the start of this.” Westpac, with its extensive retail customer base of approximately 10 million across brands like St.George, BankSA, and Bank of Melbourne, is uniquely positioned to observe these consumer trends.
The collective monthly spend of $5.6 million on AI services, while a fraction of the $6.7 billion Westpac customers annually dedicate to subscriptions, is a telling indicator. Mr. Jermyn drew a compelling parallel to the evolution of streaming services.

“Not too long ago such services didn’t exist,” he remarked, referencing Netflix’s Australian launch in 2015. “But now it and similar services are household staples.” He believes AI tools are on a similar path to becoming a “mainstream utility,” moving beyond a “niche extra.”
Beyond the Headlines: What’s Driving the Surge?
Westpac’s transaction data specifically identified spending on popular AI services such as ChatGPT, Claude, and Perplexity. It’s important to note that this analysis did not include services like Google’s Gemini, where premium chatbot access is bundled within larger productivity suites. Mr. Jermyn also acknowledged that a significant number of Australians are likely utilising free AI services, meaning the actual adoption rate could be even higher.
The substantial increase in paid subscribers is, according to Mr. Jermyn, likely fuelled by the growing demand for specialised AI tools. Services like Claude Code and OpenAI Codex, which act as AI-powered coding assistants for software engineers, are believed to be significant drivers of this trend.
Internal AI Adoption Mirrors Consumer Enthusiasm
The burgeoning interest in AI among Westpac customers is mirrored internally within the banking giant itself. In a significant move, Westpac rolled out the Microsoft 365 Copilot service to its employees in February, becoming the first major organisation in the region to do so.
“We now have more than 35,000 users of that, and the uptake has been incredible,” Mr. Jermyn reported.

The impact of AI within Westpac is multifaceted:
- Enhanced Customer Service: Employees are leveraging AI to automate routine tasks, freeing up valuable time to engage more meaningfully with customers and exercise their creativity.
- Accelerated Product Development: AI software tools are empowering Westpac engineers to rapidly prototype new product designs and features, streamlining the innovation pipeline.
“It’s really empowering our people to serve customers in a way that goes beyond what was possible before we gave them access to some of this tooling,” Mr. Jermyn concluded, underscoring the transformative potential of AI in both consumer and corporate spheres.
