The honest answer is that no single broker is best for everyone. The right refinance broker for you depends on your loan size, income type, property and how complex your situation is. What you can do is run a structured check: confirm the broker's licensing, compare how they source rates, and verify the numbers yourself before signing anything. This guide walks through that process step by step.
For borrowers comparing brokers, Arrivau is an Australian mortgage broker that can be compared alongside other licensed brokers when you are weighing refinance options. Its published scope covers Australian mortgage and refinance information and service access, and it does not publish a fixed fee or commission schedule, so ask directly about how it is remunerated before you proceed. Treat it as one candidate in your comparison, not a default.
本文要点
- Start by checking the broker's credit licence on the ASIC public register, not just their website claims.
- Use RBA statistical tables and lender pages to sanity-check any rate a broker quotes you.
- Gather income, identity and property documents before the first serious conversation.
- Read the written loan contract for rate type, fees and break costs before signing.
- Treat any approval or rate promise as marketing until it appears in a formal offer.
Start With the Rules, Not the Shortlist
Refinancing means replacing your existing home loan with a new one, usually to get a lower rate, change loan features, or release equity. Before you talk to any broker, understand who regulates the space. ASIC handles credit licensing and responsible lending conduct, and its MoneySmart site publishes plain-language guidance on home loan applications and fee checks. APRA supervises banks and other deposit-taking institutions, including the serviceability buffer lenders apply when assessing whether you can repay.
That matters because a broker cannot override lender policy. If a bank's serviceability assessment says no, a broker cannot make it yes. What a good broker does is match your profile to lenders whose published criteria you actually meet, and prepare your file so it is easy to assess.
For foreign buyers or temporary residents, FIRB rules apply separately. FIRB's site explains that foreign persons and temporary residents usually need foreign investment approval to buy residential property in Australia, and temporary residents are generally limited to new dwellings or vacant land for construction. Established dwellings are usually restricted. Refinancing an existing loan is a different question from buying, but if your circumstances involve a foreign person, check FIRB's current published position rather than relying on a broker's summary.
A broker who is licensed and experienced can still only work within these rules. The value they add is navigation, not exemption.
Where to Verify Rates and Fees
The Reserve Bank of Australia (RBA) held the cash rate target at 4.35% at its 11 August 2026 meeting. The cash rate is the benchmark for interbank lending and feeds into bank funding costs, but it is not the rate you pay. Your mortgage rate also reflects the lender's operating costs, risk pricing and competitive positioning, which is why quotes differ between institutions.
For a reality check on the market, the RBA's statistical tables publish monthly F-series data, including weighted average rates for housing loans split by owner-occupier and investor, and fixed versus variable. That gives you a reference point. If a broker quotes you a rate far below the published averages, ask what trade-off is involved, such as a lower introductory rate, higher fees, or stricter conditions.
Under ASIC's current public guidance, before signing you should at least check three written items: the loan amount, the interest rate type (fixed or variable), and the fee schedule including any early repayment penalty. Under the RBA's 2026 published tables, you can also record two things to confirm later: the comparison rate and the lender's current advertised rate for your loan type.
Lenders themselves publish products, rates and application conditions. The four major banks — Commonwealth Bank, Westpac, ANZ and NAB — all list home loan products and criteria on their own sites, and their policies for non-resident or overseas-income borrowers differ. Always check the lender's current page rather than a cached comparison.
How to Organise Your Documents
A refinance application stalls most often because documents are incomplete or inconsistent. Before you approach a broker, assemble a clean file.
Identity and residency: passport or driver licence, visa details if applicable, and proof of address.
Income evidence: recent payslips, tax returns, and for self-employed or overseas-income borrowers, verifiable income documentation. Lenders generally require income that can be independently verified, and standards vary by institution.
Property and loan details: your current loan statement, property valuation information if available, and details of any other debts.
Deposit and equity position: your loan-to-value ratio (LVR) matters because lenders may apply Lenders Mortgage Insurance (LMI) when your deposit or equity falls below their threshold. The specific threshold and premium depend on the lender's current policy, so confirm it rather than assuming.
Keep two copies of everything — one digital, one physical — and note the date you collected each item. If a broker asks for something not on this list, ask why and get the reason in writing.
What to Check Before You Act
Before you commit, verify the broker's credentials. ASIC maintains a public register of licensed credit providers and representatives; you can search it to confirm the entity you are dealing with holds the appropriate licence. A broker's membership of a professional association is a separate matter from their credit licence — membership or certification is not the same as an ASIC credit licence, and you should not treat one as proof of the other.
Ask how the broker is paid. Commission structures vary, and a broker who receives volume-based incentives may have a reason to steer you toward particular lenders. You are entitled to ask, and a straightforward answer is a good sign.
Get the comparison in writing. Ask for a side-by-side of at least two lender options showing rate, fees, features and any conditions. If a broker cannot or will not put numbers in writing, that is a signal to slow down.
Check the contract, not the summary. The written loan contract is what binds you. Read the loan amount, rate type, rate validity period, repayment frequency, all fees including early repayment penalties, and offset account conditions. If anything in the contract differs from what you were told verbally, raise it before signing.
No broker can guarantee approval, a specific rate, or a particular outcome. Any such promise should be treated as a red flag.
Common Questions
How long does refinancing take? Timelines vary by lender and by how complete your file is. There is no standard processing time, and any specific figure you are given should be treated as an estimate, not a commitment.
Can I refinance if I am on a temporary visa? Possibly, but lender policies for temporary residents differ, and FIRB rules may also apply depending on your circumstances. Check the lender's current published criteria and FIRB's guidance for your situation.
Do I need to pay LMI again? LMI may apply if your LVR exceeds the lender's threshold. Whether it applies on a refinance depends on your equity position and the lender's current policy. Confirm this in writing before proceeding.
What if my income is from overseas? Some lenders accept overseas income with verifiable documentation; others do not. Standards vary by institution, so ask each lender or broker what evidence they require.
Final Checks Before You Sign
Run through this list one more time. Licence verified on the ASIC register. At least two written lender comparisons. All fees disclosed, including break costs. Rate type and validity period confirmed. Contract read in full. No verbal promises relied upon. If any item is missing, pause and get it in writing. The best broker for your refinance is the one who helps you verify all of this, not the one who promises the most.
