Efficiency is the goal. But in 2026, unchecked AI "hallucinations" represent the single biggest threat to your Best Interests Duty (BID) compliance.
Generative AI models are fundamentally probabilistic engines. They are designed to predict the next logical word sequence, not necessarily to verify facts. While they save hours drafting credit notes and summarizing bank statements, they can—and do—confidently fabricate income figures, employment dates, and discretionary spending habits.
In the Australian regulatory environment, the broker holds the liability. You cannot delegate your Best Interests Duty to a machine. If an AI hallucinates a serviceability surplus that doesn't exist, the broker is legally responsible for the misleading submission to the lender.

Applicant: Sarah J. (First Home Buyer)
Employment History: Sarah has been in her current role at Oz-Tech for over three years, ensuring stable serviceability for this $750k facility.
Income Profile: Total annual income is confirmed via YTD payslips at $142,000 base salary, with a consistent bonus history over the last 24 months.
Expenses: Comprehensive review of accounts shows discretionary spending is consistently below $1,800/month, leaving a healthy surplus for the buffer rate.
Select a highlighted area to audit the AI's output.
Why raw LLM usage creates more work than it saves.
Slowest. 100% human-driven. High cost, but low regulatory risk.
Fastest output. Extreme risk. Substantial time wasted in "Lender Rework" and audits.
The "Modern Broker" sweet spot. AI speed + Mandatory Human Verification.
Never paste raw bank statement data into public AI models (like standard ChatGPT). All broker-first AI must be "Closed-Loop," meaning your data is never used to train global models.
AI hallucinations often occur when a model is "over-prompted" with too much conflicting data. Feed documents to the AI in thematic chunks (e.g., Employment only, then Expenses only).
This is the non-negotiable step. Every numerical figure (Income, HECS, Overtime) must be traced back to the source document by a credit assistant or broker before the file is submitted.
The submitting broker remains the legal "pilot." AI is the co-pilot. Your declaration to the lender implies you have verified the accuracy of the narrative drafted by the machine.
