From Anz warns businesses about sophisticated AI-enhanced scams ahead of Black Friday

How could the rise of AI-driven sophisticated scams affect Westpac?

Possible What happens if… A possibility worth considering, not a forecast.

Westpac may face higher security costs from AI-driven fraud The increasing sophistication of cybercrime, driven by artificial intelligence, presents a growing operational risk for major financial institutions like Westpac. Scammers are using AI to create convincing deepfake videos, clone voices, and generate perfectly worded emails for attacks like Business Email Compromise (BEC). This allows criminals to exploit trust within legitimate businesses and financial systems, as noted by ANZ. To counter this evolving threat, banks must continuously upgrade their cyber security practices, which translates into higher operational and defensive costs for Westpac.

The facts so far

As reported. Each one links to where it comes from.

  • AI is helping fraudsters impersonate trusted colleagues, businesses and even family members with a level of sophistication that can be almost impossible to detect.sbs.com.au
  • Identity fraud was the most common scam reported in 2025.sbs.com.au
  • ANZ customer scam losses fell by 24 per cent between October 2025 and June 2026 compared with the same period the previous year.sbs.com.au
  • ANZ prevented and recovered more than $100 million in scam and fraud-related funds during that period.sbs.com.au

Why it matters

For Westpac, the primary stake is maintaining customer trust and managing financial exposure. As AI makes scams harder to detect and hides them within legitimate transactions, the bank faces a continuous 'arms race' against criminals. This requires significant, ongoing investment in cybersecurity infrastructure and staff training to mitigate the risk of losses from BEC, payment redirection, and identity fraud.

This threat is systemic across the Australian financial sector. ANZ, a major competitor, has already seen its scam losses fall by 24 per cent while recovering over $100 million, demonstrating that coordinated action works. However, experts warn that the technology is evolving rapidly, meaning that the need for robust, proactive defense mechanisms will only increase for all large financial institutions.

What we don't know yet

  • How quickly will new AI-driven scam techniques become routine across the industry?
  • What specific regulatory changes might be required to manage the risk posed by deepfake fraud?

What would change this answer

Criminals widely adopt real-time deepfake video calls for scamsThe risk to Westpac would increase significantly, as human judgment, currently cited as a strong defense, would become much harder to rely upon.
Banks and telcos successfully deploy new AI tools to detect and prevent cybercrimeThe operational costs associated with fraud could stabilize or decrease, reducing the long-term pressure on the bank.
