Key Desk Findings

  • 01Since July 2026, non-bank lenders have joined authorised deposit-taking institutions (ADIs) inside Australia's Consumer Data Right (CDR) perimeter.
  • 02Underwriters can no longer treat non-bank auto, personal, and specialist facilities as opaque 'off-bureau' black boxes when consented transaction feeds are available.
  • 03The biggest operational win is not replacing bureau pulls, but reconciling CDR repayment schedules directly against bank account direct debits in under five seconds.

Why Pure LLM Transaction Categorisation Fails in Production Underwriting

Large language models excel at deciphering cryptic merchant strings, but putting them in the hot path of every transaction breaks latency, determinism, and auditability.

Core Thesis

A typical 24-month multi-account CDR payload contains 2,500 to 6,000 transaction rows—far too large for synchronous LLM inference within a 5-second SLA.

Two Borrowers, Identical 760 Bureau Scores, Opposite Default Trajectories

Why backward-looking credit bureau tradelines miss acute liquidity exhaustion—and how buffer days and payday stacking separate resilient borrowers from fragile ones.

Not every debt obligation appears on a credit bureau header. Here is how credit analysts use transaction periodicity to uncover off-bureau commitments.

Core Thesis

Several high-impact financial commitments—including ATO tax payment plans, earned wage access (EWA) advances, private family loans, and certain salary-sacrificed or novated shortfalls—frequently do not appear as standard consumer bureau tradelines.
