What Melbourne Mortgage Brokers Pay for AI Automation

A borrower who submits an enquiry at 9pm on a Tuesday has usually sent the same details to three brokers. The one who replies first with a usable rate indication tends to win the loan, and the other two never hear back. For a Melbourne mortgage broker, the cost question is not really "can I afford AI automation" but "how many settled loans am I already losing to the broker who replies in five minutes."

Here is what AI automation genuinely costs a mortgage brokerage to set up and run, what it pays back, and the situations where it is not worth it. All figures are estimates in AUD.

What you pay to set it up

A useful first automation for a broker is rarely a single chatbot. It is a small set of connected pieces: a lead-capture form and missed-call handler that replies instantly day or night, an agent that follows up an enquiry over SMS and email until the borrower responds, an automated document checklist that texts the borrower exactly what to upload (payslips, ID, bank statements), and a status-update flow that keeps the borrower informed so they stop chasing you.

Building that from a blank slate, on a fixed-price basis, typically lands somewhere between $3,000 and $6,000. The lower end covers a focused lead-follow-up and document-collection flow for one broker. The higher end covers a multi-broker office with lender-specific quoting, CRM integration, and a trained phone-answering agent that can book appointments and answer common questions out of hours.

The reason a fixed price matters here is that AI work expands fast when it is billed hourly. A clear scope up front stops a three-week build quietly becoming a three-month one.

What you pay to keep it running

Once it is live, the ongoing cost is mostly usage, not labour. Expect roughly $150 to $450 a month for a typical brokerage, made up of:

• AI and automation platform usage, which scales with how many leads and messages flow through.
• A dedicated mobile or 1300 number, and SMS sending. SMS is still the highest-converting channel for borrowers.
• A phone-answering or voice agent, if you use one, billed per minute of call time.
• Small monthly tweaks: a new lender to quote, a new document type, a changed follow-up sequence.

Compare that to the alternatives. A part-time admin or junior BDM on $25 to $35 an hour, even at 15 hours a week, is $1,500 to $2,000 a month and cannot answer a 9pm enquiry at all. An after-hours answering service charges per call and only takes messages. It does not follow up, collect documents, or book the appointment.

The payoff: how many extra loans

This is the part that actually matters. A settled residential loan is worth roughly $2,500 to $4,000 in upfront commission to a broker, plus a trailing commission over the life of the loan. So the maths is simple. The automation only needs to help you convert a handful of extra loans you would otherwise have lost, and it has paid for itself.

Say you get 40 enquiries a month and currently convert 8 of them. If faster, persistent follow-up and a smoother document collection lift that to 10 or 11, you have added two to three extra settlements a month. At a conservative $3,000 upfront each, that is $6,000 to $9,000 a month in additional commission against a few hundred dollars in running costs. The setup pays back inside the first month or two in that scenario.

The less dramatic but more common win is the lead you would have lost to slowness. A borrower who enquires after hours and gets an instant, specific reply (thanks, on a $600k purchase with a 10% deposit you are looking at roughly this rate, here is the document list, want a 15-minute call tomorrow at 9?) is far less likely to keep shopping. Speed is the product in broking, and automation is mostly a speed tool.

When it is not worth it

Honest version: automation speeds up a process that already exists. If you do not have much of a process, or not enough volume, it has nothing to speed up.

• If you are a sole broker with a small, steady pipeline of five to ten enquiries a month, nearly all from existing clients and referrers, and you already reply within the hour, the marginal gain is small. Your money is better spent generating more leads first.
• If you have no CRM and your leads live in a spreadsheet you update weekly, fix that first. Automation on top of a broken capture process just automates the leak.
• If your deal is almost entirely referral and relationship-based with little rate-shopping, the "first to reply wins" dynamic is weaker, so the ROI is weaker too.

What a realistic first month looks like

Week one is scoping and build: mapping your enquiry flow, wiring up the form and SMS, building the document checklist. Week two is testing on real or staged leads and training the agent on your lenders and qualifying questions. Week three it goes live and you watch the first follow-ups go out. By week four you can usually point to specific loans in the pipeline that came from an instant reply or a document chase you no longer had to do manually.

Is it worth it for your brokerage?

If you get a steady stream of enquiries and you know you are losing some to slow follow-up or document friction, almost certainly yes, and the payback tends to be measured in weeks, not years. If your volume is low or your follow-up is already fast and tight, the case is weaker and you should fix the top of the funnel first.

The cheapest way to find out is a free AI workflow audit. Rootech maps your enquiry-to-settlement flow, spots the two or three steps costing you the most loans, and tells you honestly whether automation will pay back.
