Aussie Launches Rate Radar to Alert Borrowers on Refinancing

The Lendi Group brokerage Aussie has launched a mortgage-monitoring tool that pings borrowers and brokers the moment a better rate becomes available.

Refinancing at the right moment is one of the biggest financial opportunities available to Australian mortgage holders — and one of the most consistently missed. Most borrowers only think about their rate when a lender sends a letter or a broker makes a scheduled check-in call. Major brokerage Aussie, part of the Lendi Group, has launched a tool designed to change that dynamic: a mortgage-monitoring feature called Rate Radar, announced on 4 June 2026.

As The Adviser reports, Rate Radar is now available to Aussie app users and represents a meaningful shift in how clients can track refinancing opportunities without doing any of the legwork themselves.

How Rate Radar Works

The setup is straightforward. Borrowers connect their existing home loan to the Aussie app — either by linking their loan account directly or entering their loan details manually. Once connected, they set a specific annual savings target that would prompt them to consider refinancing — for example, $1,000 per year.

From that point, Rate Radar scans the market continuously against the borrower's current loan credentials. It tracks variable-rate options and can set reminders for fixed-rate loans approaching their expiry date. When a market alternative reaches or exceeds the borrower's preset savings threshold, both the borrower and their broker receive a notification simultaneously. The client can then schedule an appointment with their broker directly through the app.

The system replaces traditional manual follow-up processes — the calendar reminders and periodic check-in calls that have been the broking industry's standard workflow for years.

Aussie CEO Sebastian Watkins, quoted by [The Adviser](https://www.theadviser.com.au/tech/48515-aussie-launches-rate-radar-tool-for-borrowers), described Rate Radar as a "passion project" that solves one of the central problems in mortgage broking: what happens to the client relationship between transactions. "Today, most brokers stay in touch through periodic reviews and health checks. Every six months. Maybe every 12 months. But the reality is that customers don't become ready on a schedule," he said.

Watkins also highlighted one of Rate Radar's more underrated features: its ability to flag borrowers who cannot be helped yet — those who lack sufficient equity, have no matching market options, or for whom a refinance doesn't stack up financially right now. Historically, those clients would be diarised for a callback six or twelve months away, with brokers hoping to catch them at the right moment. Rate Radar removes that guesswork by monitoring each client's position continuously and triggering action only when the conditions actually align.

"The second a savings opportunity appears, or their equity position improves enough to act, we'll know," Watkins said. "The customer gets the good news, the broker gets the opportunity, and the conversation happens at exactly the right time."

The Rate Radar launch is part of a broader technology push. The Lendi Group has set a target of having artificial intelligence extend into all areas of its business by the end of June 2026. Over 1,350 Aussie brokers across 220 stores are expected to use AI throughout the home loan process, with agentic AI — systems designed to autonomously perform tasks when instructed — being rolled out to assist brokers with tasks ranging from email responses to administrative duties. Further digital updates to the Aussie platform are scheduled for next month.

What This Means If You're Sitting on an Old Loan

For borrowers, Rate Radar is a useful prompt to reflect on something important: most of us are passive when it comes to managing our mortgage. We sign up, we set up a direct debit, and we largely forget about it. In a market where variable rates have moved materially over the past few years, that passivity can quietly cost thousands of dollars a year.

The core principle Rate Radar is built on — that your loan should be monitoring the market for you, rather than you needing to remember to check — is sound regardless of which broker or lender you use. If your home loan hasn't been reviewed in the past twelve months, there is a reasonable chance you are not on the most competitive rate available. Our [refinance savings calculator](/calculators/refinance-savings) is a fast way to get a ballpark sense of what switching could mean for your monthly repayments.

Rate Radar also highlights a structural gap in how borrowers and brokers currently connect. Typically, that connection happens only when the borrower initiates contact or a lender's promotional offer arrives in their inbox. Automating that trigger point — as Aussie has done — should mean better-timed conversations and better financial outcomes for borrowers who might otherwise drift on an uncompetitive rate for years.

It is worth noting that Rate Radar is specific to Aussie's platform and its broker network. But the principle it embodies — regularly benchmarking your loan against what the market is offering — is something every borrower should be doing, whatever tools they have access to. [Exploring your refinancing options](/home-loans/refinance) with a broker who can compare across a broad range of lenders and loan structures is always a worthwhile exercise.

Other major brokerage networks have been moving in a similar direction. Mortgage Choice has integrated buyer and seller intent scores from PropTrack into its CRM, giving its more than 1,100 brokers a clearer picture of where customers sit in their property journey. Loan Market has also rolled out AI assistant tools to its brokers. These developments collectively point toward an industry moving to more proactive, data-informed client management — and for borrowers, that shift can only be a good thing.
