Westpac: 12,500 banker hours saved in the first month of operation, July 2026

Westpac (banking) reported this on 5 Aug 2026 in company self-report (source). It belongs to the agents, traceability and evals layer.

What they built

Five specialist agents on Amazon Bedrock AgentCore that classify and read payslips and bank statements, run serviceability calculations and verify them against lending policy, then hand the banker a result to review for mortgage and credit-card applications.

The result

12,500 banker hours saved in the first month of operation, July 2026, annualised at 150,000 hours (AFR, 5 August 2026).

The number covers lending assessment work across mortgage and credit-card applications; first month of operation.

Guardrails

Specialist agents each handle one step (bank-statement scrutiny, payslip extraction, policy verification); a verification agent checks payslip details against policy and required calculations; the banker reviews the output and continues the application.

The layer: agents, traceability and evals

Each agent has one narrow task, a named owner and an action log.

  • Agents with one narrow job and an identity
  • A trace of every tool call and decision
  • Eval sets that gate every change
