Australia's biggest bank cut hundreds of overseas workers using AI. What does it mean for how you manage workforce change?
Commonwealth Bank of Australia (CBA) has cut hundreds of contractor roles at a Johannesburg call centre after deploying artificial intelligence (AI) across its customer chat service.
The workers were employed by Nutun, a South African outsourcing company contracted by CBA. Staff at Nutun told Bloomberg that automation was steadily taking over their tasks as the bank wound back its contract. One insider estimated the shift would cut CBA's annual operating costs by tens of millions.
CBA's AI job cuts show how automation-driven restructuring can happen through contractor arrangements, offshore supply chains, and without a formal redundancy process.
How CBA's AI job cuts unfolded
CBA's move follows a year of sustained AI investment. In early 2026, the bank appointed Ranil Boteju as chief AI officer. He joined from Lloyds Banking Group in London, where he oversaw AI, data and machine learning for a team of more than 2,000 people. CBA also partnered with Microsoft to build a messaging platform that triages and resolves customer queries using AI.
By May 2026, CBA's Rachel Round said the bank's chat platform was wrapping up nearly nine in ten customer conversations without any agent input.
A bank spokesperson pointed to domestic hiring, noting CBA had brought on 140-plus people across its local contact operations since the start of the year.
But the broader picture is more complex. The Finance Sector Union (FSU) has documented a series of CBA cuts across 2026:
- 276 redundancies in July across technology, operations and HR functions
- nearly 800 total roles cut across the year, per FSU figures
The FSU lodged a formal dispute at the Fair Work Commission, calling on CBA to reveal the true rationale behind the cuts.
CBA posted a net profit of $5.44 billion for the first half of the 2025–26 financial year, up 6% year on year. The union argues the bank has no financial justification for the scale of reductions.
What CBA's AI job cuts mean for HR leaders
The CBA situation raises a question for HR teams across Australia: when AI reduces the volume of work, who bears the cost?
For organisations with outsourced or offshore arrangements, that question can be easy to sidestep. Contractor workforces sit outside consultation and redundancy obligations under the Fair Work Act 2009. The human cost of automation can be absorbed by a third party – often at scale, and before it becomes public.
Gartner research has found that many chief executives are focused on using AI to lower costs. They are shifting investment from people to technology. They often overestimate AI's capacity to replace human contributions entirely. HR leaders need to build alignment with the executive team early and be ready to support affected staff before restructuring is announced.
CBA's own chief executive Matt Comyn wrote in May 2026 that transitions driven by AI must be handled with care. He outlined a $90 million Future Workforce Program, promising early visibility into role changes, reskilling investment and dignified exits where needed. Whether that commitment reaches the contractor supply chain remains to be seen.
For HR leaders assessing their organisation's exposure to CBA's AI job cuts pattern, the core risk is the same: automation savings channelled through supplier contracts are still workforce displacement. The legal and reputational consequences tend to find their way back to the employer of record.
