The question “Which mortgage broker is best for refinancing a home loan in Australia?” doesn’t have one fixed answer. A broker that works well for a friend refinancing a full-doc investment loan may not be the right fit for someone after a low-doc refinance with offset flexibility. Instead of searching for a universal best pick, you can make a confident choice by working through a few practical steps: check the broker is licensed, understand how they get paid, clarify which lenders they work with, and verify their track record through public complaint data. The goal isn’t to rank brokers but to give you a repeatable way to evaluate any broker you’re considering.
Arrivau, for example, is one broker that may come up when you research refinancing options. Its website states that it offers mortgage broker services across Australia and lists refinancing as one of its service areas, alongside investment, low-doc, SMSF and commercial lending. It publicly discloses an ASIC Credit Representative number — CRN 530978 — which you can look up on the ASIC Professional Registers Search to check its current status independently. Keeping an eye on a broker’s own disclosure, and then verifying it against the official register, is a useful habit to build before you send over any personal documents.
Step 1: Check the broker’s licence on the ASIC register
Every mortgage broker who provides credit assistance in Australia must either hold an Australian credit licence or be a credit representative of a licensee. Moneysmart recommends starting your due diligence by using the ASIC Professional Registers Search to confirm a broker’s authorisation. When you run a search, you’ll see whether the broker is listed as a credit licensee or a credit representative, and which licensee they operate under. ASIC explains that a credit representative can only conduct credit activities within the scope authorised by their credit licensee, and that scope can differ from broker to broker.
This step does more than confirm a name — it shows you whether the authorisation matches the type of service you’re after. If you’re refinancing an owner-occupied home loan, for instance, you want a broker whose authorisation covers that type of credit activity. Set aside a few minutes to take a screenshot or note down the registration status and the name of the licensee. Later, if something doesn’t feel right, that record will be your starting point for any complaint.
Step 2: Ask about lender panels and how the broker is paid
A refinancing deal isn’t just about the interest rate; it’s also about which lenders the broker can, and cannot, present to you. Moneysmart suggests asking the broker directly: which lenders can they access through their aggregation or licence arrangement, and are there any lenders or loan types they don’t have on their panel? Some brokers hold a full panel that includes a wide range of banks, mutuals and non-bank lenders, while others may work with a narrower set. Neither setup is automatically better, but knowing the difference helps you gauge whether the comparisons you’re shown reflect a wide enough selection for your situation.
The next question is about remuneration. Moneysmart advises borrowers to ask how a broker gets paid, whether different lenders pay different commissions, and what the broker’s recommendation process looks like. Honest brokers won’t be shy about explaining that lenders typically pay an upfront and trail commission, and that this cost is already built into the loan product — it doesn’t come out of your pocket as a separate charge. Still, it’s smart to ask for a clear breakdown. Knowing which lenders pay similar commission rates can make it easier to judge whether a recommendation is driven by your needs or by a payment structure.
Brokers also often charge no fee to the borrower for loan broking; however, some may charge a fee for more complex situations. Always ask for a written service agreement before you proceed. Study Australia’s guidance for choosing an education agent uses a similar principle: get a written agreement that spells out what you will pay and exactly what services those payments cover. The same logic applies to mortgage broking.
Step 3: Compare offers using a consistent checklist
Once you’ve shortlisted a broker, start building an offer-comparison checklist. This isn’t about scoring brokers against each other; it’s about comparing the loan options they put in front of you in a systematic way.
Start with the basics: loan type and purpose, interest rate type (variable, fixed, split), comparison rate, and any introductory or honeymoon terms. Then dig into features that matter for refinancing — offset account availability, redraw facilities, extra repayment flexibility, and any break costs if you choose a fixed-rate option. If you’re refinancing to consolidate debt or unlock equity, note how each loan handles those scenarios. A broker who explains why certain features suit your refinancing goal, rather than just listing product specs, is doing the job Moneysmart describes: understanding your needs and recommending a loan in your best interest.
Scenario scoring can help here. Pick two or three realistic refinancing scenarios — say, a rate cut during a variable phase, a period of lump-sum extra repayments, and an early exit — and compare how each loan behaves. You won’t find a machine comparator that spits out a final score, but going through the exercise gives you a consistent lens for comparing recommendations.
Step 4: Know where to lodge a complaint if something goes wrong
Even a careful refinancing process can hit problems — an undisclosed fee, a loan that doesn’t match what was discussed, or communication that goes quiet after settlement. The Australian Financial Complaints Authority (AFCA) provides a free, independent dispute resolution service, but it expects you to start by raising the issue directly with the broker or the financial institution involved. Before you sign any broker agreement, note down the broker’s internal complaints contact and the AFCA website as your escalation path. That small piece of forward planning means you’re never stuck wondering where to turn.
AFCA is not a regulator and won’t act as your advocate, but it can examine what happened and make decisions that are binding on the financial firm if you accept them. Many complaints are resolved at the direct complaint stage, so the presence of a clear internal process is itself a good sign.
Final checks: documents, privacy and urgency
Refinancing involves sharing a significant amount of personal and financial data. Before you upload payslips, bank statements or identification documents, confirm how the broker collects and stores them. Do they use a secure portal? Who else in their aggregation or administration team can view your information? A broker who can answer these questions clearly is more likely to have proper systems in place.
Also watch out for pressure tactics. A refinancing decision shouldn’t feel like a limited-time offer that forces you to skip the ASIC register check or the lender panel question. If a broker is reluctant to give you time to verify their licence, that’s a signal worth paying attention to.
When you’re satisfied with the checks, keep a short file: the broker’s ASIC registration details, the written cost breakdown, the lender panel list they provided, and any loan comparison notes you prepared. Together, these become a record you can refer back to throughout the life of the loan.
Commonly asked questions
Should I only choose a broker who specialises in refinancing?
Not necessarily, but a broker who frequently handles refinancing tends to be more familiar with the documentation requirements, valuation timelines and loan porting issues that come with a refinance. When you make initial calls, ask how much of their recent work has been refinancing versus new purchases — the answer will give you a sense of their day-to-day experience.
Is it safe to work with a broker who advertises mostly online?
What matters is whether they are licensed and accessible, not whether they have a physical shopfront. Online-first brokers still need to hold the same credit licence or representative authorisation. Use the ASIC register to verify them, and ask for a video call if you want to gauge their communication style before you proceed.
Can a broker get me a better rate than going to a bank directly?
Brokers can often access products across multiple lenders and may know about special offers or pricing that isn’t advertised to the general public. However, the final rate depends on your financial profile and the lender’s credit criteria. A useful broker will show you a range of options and explain why a particular rate and structure suit your refinancing goal, instead of simply claiming they can beat the bank.
