Westpac is expanding its use of artificial intelligence (AI) across the business lending process, aiming to embed the technology at every stage—from credit assessment to customer engagement.

The bank’s expanded investment in AI follows similar efforts by rival Commonwealth Bank, signaling an industry-wide push to modernise business banking through advanced analytics and automation.

Westpac recently offered a behind-the-scenes look at its partnership with RDC.ai (formerly Rich Data Co), established in 2021.

The collaboration—developed alongside Amazon Web Services (AWS)—has since evolved to incorporate generative and Agentic AI capabilities, broadening applications beyond traditional credit decisioning.

According to Westpac, AI is now playing an increasing role in evaluating business loan applications and identifying new value within the bank’s data assets.

Meanwhile, Westpac introduced an AI-powered call assistant, currently in pilot with its specialist scam and fraud team, that analyses live customer calls to detect potential scams and help operators respond swiftly and consistently.

The assistant is being developed through Westpac’s broader ‘AI Accelerator’ program, which is focused on embedding intelligent automation across the bank.
