How to Refinance a Home Loan in Australia: The Smart Guide
Did you know one-in-four Aussie homeowners refinance their mortgage within just five years? With interest rates still elevated and personal finances under pressure, refinancing may be one of your smartest moves.
In Q1 of 2025 alone, 65,030 home loans were refinanced between lenders, a 5.1% jump on the previous period. Refinancing activity hit an 18-month high as rate competition intensifies and borrowers hunt for savings. Meanwhile, the average variable home loan rate for owner-occupiers sits around 6.15% as of August 2025.
This guide is your blueprint for navigating refinancing in Australia — from reducing interest costs and unlocking equity to knowing when and how to switch.
Whether you’re a homeowner down the street or an expat managing property from abroad, we’ll walk you through the process, hidden costs, common mistakes — and how to make the right move at the right time.
What Is Refinancing a Home Loan and Why Consider It?
Refinancing a home loan means replacing your current mortgage with a new one—either from your existing lender or a new one. This is usually done to get a better deal or match your changing financial situation.
Many Australians and expats refinance their home loan to access equity, cut costs, or restructure their loans. But refinancing isn’t just about switching loans—it’s a smart financial strategy that can significantly impact your long-term wealth.
This process can occur in two main ways:
- External Refinancing: Switching the home loan to a completely different lender.
- Internal Refinancing: Moving to a different home loan product offered by the existing lender.
According to the Reserve Bank of Australia, refinancing activity has surged in recent years as borrowers chase better refinance rates and lower repayments
Refinancing can help in several ways:
- You may reduce your interest rate and save thousands over the life of your loan.
- You might unlock equity in your property for renovations or investments.
- Or you could restructure your loan for better cash flow or debt management.
Let’s break down the real benefits of refinancing so you can decide if it’s the right move for you.
Saving Money with a Lower Interest Rate
Switching to a lower interest rate is the most common reason Aussies and expats refinance. A small rate drop—even by 0.5%—can save you tens of thousands over your loan’s lifetime.
Let’s say you have a $600,000 loan at 6.5%. If you refinance to 6.0%, your monthly repayments drop, and you could save over $20,000 in interest across 30 years.
Many lenders offer sharper rates to new customers compared to existing ones. Refinancing lets you tap into those deals. This is especially important for expats, as some banks offer better terms depending on how your foreign income is assessed.
Accessing Home Equity
If your property has grown in value, refinancing lets you unlock some of that growth as cash. This is also called cash-out refinance. It’s a powerful way to leverage your existing assets for future growth.
Make sure to consult a broker about Loan-to-Value Ratio (LVR) limits and equity release conditions, especially if you’re earning overseas income.

Consolidating Debt
If you have multiple high-interest debts like credit cards or personal loans, refinancing can help you combine them into one mortgage with a much lower rate.
By consolidating debt through home loan refinancing, you simplify repayments at a lower rate. You only need to make one repayment at your home loan rate (around 5–6%) instead of multiple repayments at 15–20% interest. This can simplify your finances and reduce your total interest, but you must manage the longer loan term carefully.
Switching Loan Features or Types
Your current loan may lack features that could improve your cash flow or reduce your interest over time.
With refinancing, you can:
- Add an offset account to lower interest on your principal.
- Switch from fixed to variable (or vice versa) for more flexibility.
- Choose redraw facilities that let you access extra repayments.
These features can make a big difference for Aussie expats managing foreign income and savings across currencies.
Paying Off Your Mortgage Faster
Refinancing isn’t just about reducing payments—it can also help you pay off your loan faster.
You could switch to a shorter loan term, increase repayments, or find a lender with fewer restrictions and better repayment flexibility.
For instance, moving from a 30-year to a 20-year loan term can save thousands in interest, even if monthly payments are slightly higher.
Finding Flexible Options & Competitive Rates
Banks change their offerings frequently. The deal you signed up for five years ago might not suit you today.
Refinancing opens the door to more competitive rates, flexible features, and lenders who may be more expat-friendly.
With access to various lenders, a broker can compare multiple offers to find the best home loan refinance for your needs—especially if you’re overseas or have complex income streams.
Exploring Different Types of Home Loan Refinancing
Refinancing isn’t one-size-fits-all. There are many types of refinance you can choose depending on your financial goals—whether you want to lower your rate, access equity, or shorten your loan term.
Each option has its own benefits, risks, and best-use scenarios. Understanding the key differences between refinance home loan types will help you make the right choice when talking to lenders or your mortgage broker.
Let’s explore the most common types of home loan refinance available for Aussies and expats.
1. Rate-and-Term Refinance
Rate-and-term refinance is the most straightforward type of refinancing. You keep the same loan amount but change the loan term or interest rate—or both.
For example, you may switch from a 6.5% variable rate over 30 years to a 5.9% fixed rate over 25 years. This can help you lock in savings and adjust your monthly repayments.
Most borrowers choose this refinance to cut costs or gain more control over their cash flow. It’s especially useful if you’re no longer on a competitive rate.
2. Cash-Out Refinance
A cash-out refinance allows you to tap into your home equity by borrowing more than what you currently owe and taking the difference in cash.
Let’s say your property is worth $850,000 and your remaining loan is $500,000. You could refinance for $600,000 and take the $100,000 difference in cash.
This is ideal for large expenses—like renovations, investments, or major life events—but comes with increased debt, so it should be used wisely.
Cash-out refinancing is becoming more popular as property values rise.
3. Cash-In Refinance
Unlike cash-out, cash-in refinancing means you pay extra upfront when refinancing to lower your loan balance.
This is helpful if your Loan-to-Value Ratio (LVR) is too high or you want to qualify for a better interest rate. Lenders usually give better rates when your LVR drops below 80%.
Expats could use refinancing to strengthen their application—especially when foreign income policies are strict.
4. Debt Consolidation Refinance
A debt consolidation refinance rolls multiple debts—like personal loans, credit cards, and car loans—into your home loan.
It simplifies your repayments and usually reduces your interest rate significantly. But be careful: turning short-term debt into long-term debt may increase the total amount you repay over time.
Make sure to plan repayments carefully to avoid racking up debt again.
5. Rapid Refinance
Also called fast-track refinance, a fast refinance is designed to move your loan to a new lender quickly—often within 5–10 business days.
It’s ideal if your current lender is slow or if you need to access new funds urgently (such as to meet an investment deadline).
But keep in mind, not all lenders offer rapid refinancing, and some may still require full documentation.
How to Refinance a Home Loan in Australia: The 9 Step Home Loan Refinance Process
Refinancing might feel overwhelming—but it doesn’t have to be. If you follow a clear process, you’ll know exactly what to expect at each step.
Below is a simple, 10-step guide to the home loan refinance process. It applies whether you’re an Aussie resident or an expat living overseas.
Step 1: Figure Out Why You Want to Refinance
Start by clarifying your goal. Are you trying to refinance your home loan to save on interest? Unlock equity? Consolidate debt?
Being clear about your reason helps you—and your broker—find the right refinance type and lender.
👉 Helping you decide:
Step 2: Comparing Lenders and Refinance Offers
Once you know your goal, compare offers. Don’t just look at interest rates—check features, fees, and flexibility.
- Interest Rates: Look beyond the advertised rate and check the comparison rate. This includes fees and charges. Online Comparison Rate Calculator can help.
- Loan Features: Consider features such as offset accounts, redraw facilities, split loans, fee waivers and cashback deals.
- Loan Terms: Calculate the total amount you will be paying over the life of the loan and compare the amount when switching versus not switching. This can be tricky. For example, if you switch to a new 30-year loan, your monthly repayments might decrease. But you will pay less principal and more interest leading to increased total repayments. On the other hand, a shorter loan term of 15-20 years means higher monthly payments with more principal and more/same interest, but you’ll pay off your loan faster, and save on total interest leading to decreased total repayments.
- Fees and Costs: Assess potential costs, including break fees (for fixed loans), discharge fees, valuation fees, and application fees of new lenders.

Step 3: Talk to a Mortgage Broker
A mortgage broker simplifies the home loan refinance process. They’ll assess your financials, recommend lenders, and handle the paperwork.
They’re especially helpful for expats who may need to meet extra requirements around income, documentation, and tax status.
Mortgage brokers are paid by lenders through commissions, so you do not pay anything extra. They are legally required to act in your best interests, which is great for you. Just be sure to ask if they work with all lenders or only a few select ones, so you know you’re getting the best options.
Step 4: Calculate Costs and Fees Associated with Refinancing
Refinancing isn’t free. You may face exit fees, new lender fees, valuation costs, and more.
Common refinance costs include:
- Discharge Fees: $200-900
- Application Fees: $150-1,000
- Valuation Fees: $200-500
- Ongoing Costs: $300-400 per year
- Break Costs: If you are on a fixed-rate loan
- Stamp Duty: $0 – $15,000+
If your new loan results in an LVR above 80%, you may need to pay Lenders Mortgage Insurance (LMI) again. This can add thousands of dollars to your costs. For example, LMI for a $500,000 loan with 85% LVR can exceed $10,000.
Make sure the savings from refinancing your home loan outweigh the costs. Pro tip: Ask your broker for a break-even analysis to see how long it will take before you’re actually ahead.

Step 5: Calculate How Much You Will Save by Refinancing
Use a home loan refinance calculator to check how much you’ll save monthly and over the life of your loan. Just plug in your current loan, interest rate, and new rate to see your savings.
If the total saving is significant and the break-even period is short, refinancing is likely worth it.
Step 6: Get Your Documents Ready
Lenders will want documents like:
- Your ID (passport or driver’s license)
- Income proof (payslips or tax returns)
- Details of your existing loan
- Living expenses and liabilities
- Property information
Expats may also need:
- Foreign income statements
- Overseas employment letters, and
- Translated documents
👉 More details in Documents required for refinancing
Step 7: Submit Your Application
Once your documents are ready, your broker or lender will submit the refinance application.
They may also request additional information, especially if you have complex income or live overseas. Quick responses help avoid delays.
Step 8: Valuation and Assessment
The lender will order a valuation of your property to confirm its current market value.
This helps determine your new LVR and loan approval. If your property value has gone up, you might unlock equity and avoid LMI.
Step 9: Approval and Settlement
After valuation and assessment, the lender will assess your application. Here’s what you can expect:
- Loan Assessment and Approval: The lender reviews your financial documents, credit score, and property valuation to assess your eligibility. If everything meets their criteria, they issue formal loan approval or unconditional approval.
- Loan Contract Signing: You will receive a loan contract outlining your new loan terms that include repayment schedules, interest rates, and loan features. Carefully review, sign, and return it to the lender.
- Discharge of Existing Loan: Your new lender will pay off your old loan by working with your old lender. This can take a few days/weeks.
- Settlement and Transition: Once the old loan is closed, you begin making repayments under the new terms.
Your broker will arrange a settlement with your current lender. Maintaining communications with your lender or mortgage broker throughout this process will help avoid delays.
Once settled, you’ll receive formal approval and your new home loan refinancing terms begins. And any extra cash (if doing a cash-out refinance) is transferred.
This concludes the main steps on how to refinance a home loan in Australia.
How Long Does Refinancing Take?
Typically, refinancing takes 2–6 weeks, depending on your lender, how quickly you provide documents, and your property valuation.
- Fastest (2–7 days): Some lenders offer quick services for eligible borrowers.
- Average (4–6 weeks): Most applications take this long due to assessments and property valuations.
- Longer (6+ weeks): Missing documents or complex finances can cause delays.
Some lenders offer rapid refinance in under 10 days, but this may come with stricter conditions.

How Can You Calculate Your Repayments?
Use a loan repayment calculator to estimate your monthly payments based on the loan amount, interest rate, and loan term. Most banks and brokers offer these free tools online.
For example, if you’re borrowing $700,000 over 25 years at 6.0%, your monthly repayment is around $4,510. If you refinance at 5.5%, it drops to $4,300—saving you over $2,500 a year.
The Value of a Mortgage Broker
You could refinance on your own—but working with a mortgage broker can save you serious time, money, and stress.
A good broker will:
- Compare dozens of lenders for you.
- Recommend options that suit your goals.
- Help with paperwork and follow-up.
- Provide insider tips for refinancing, especially for expats.
If you’re living overseas or earning foreign income, some lenders won’t deal with you directly—but brokers can still access those deals.
Most brokers are paid by lenders (not you), so you won’t pay anything extra.

Common Refinancing Mistakes to Avoid
Refinancing is powerful—but done wrong, it can backfire. Here are some common mistakes Aussies and expats should watch out for:
1. Not Shopping Around
Many borrowers just take the first offer they see—or stay with their current bank. This means missing out on better deals.
Always compare multiple lenders or use a broker to see all your options.
2. Focusing Only on Interest Rate
A low rate is great—but if the loan has high fees or lacks features, it might cost more in the long run.
Look at the comparison rate, which includes fees and charges, and consider features like offset accounts. Avoid focusing only on rates when refinancing a home loan—compare fees and features too.
3. Ignoring Fees and Costs
Some people refinance for a slightly lower rate—only to find the switch costs more in fees than it saves.
Always calculate your break-even point and total cost of refinancing before you commit.
4. Refinancing Too Frequently
Switching too often can lead to hidden costs, exit fees, and loan fatigue. Lenders might even see it as a red flag.
Aim to refinance only when it brings a clear benefit.
5. Impact on Your Credit Score
Every refinance triggers a credit check. Too many inquiries in a short time can hurt your score.

When Is the Right Time to Refinance Your Home Loan?
There’s no perfect time—but some situations make refinancing a smart move.
If interest rates have dropped, your income has improved, or your property value has gone up—it might be time to switch.
Below are some examples of good times to consider refinancing your home loan.
- Official RBA cash rate or lenders interest rates have dropped.
- Your introductory or fixed-rate period has ended.
- Your financial situation has improved.
- Accessing home equity for renovations, investments, or debt consolidation.
- You want better loan features such as an offset account, redraw facility, or split loan options.
- You want to lower monthly repayments by switching to a longer-term loan.
👉 More details in:
Should You Refinance After Interest Rate Changes?
Yes—rising or falling rates are key triggers to review your loan.
If rates are rising and you’re on variable, you might want to lock in. If they’re falling, switching lenders could unlock better deals.
How Often Can You Refinance a Home Loan?
Technically, you can refinance as often as you want in Australia. But most experts recommend waiting at least 12–18 months between switches.
This gives time to build up equity, recover fees, and make the most of your current rate.
👉 Learn more in How Often Should You Refinance Your Home Loan?
Considering Your Loan Term Reset
Refinancing often resets your loan term. If you’ve already paid off 5 years and reset to 30 years, you could pay more interest overall.
Ask your broker to shorten your new loan term to match your goals—or make extra repayments to offset the difference.

Are You Eligible to Refinance Your Home Loan?
Most Aussies and expats are eligible—but lenders have different policies.
They’ll assess:
- Your Current LVR: Lenders are more likely to approve your application if your LVR is 80% or lower. This reduces risk for lenders.
- Your Income (and Currency): Lenders want proof of steady income.
- Your Credit History: A high score (622-1200) will improve your chances for approval and better rates.
- Your repayment record
- Existing Debts: Lenders check your current debts to ensure you can afford repayments. If you have too much existing debt, it may lower your chances of approval.
If you’re an expat, make sure your income is from an accepted country and that you can provide the right documents.

Refinancing can save money and unlock flexibility—but it’s not always the right move.
Here’s how to decide if it suits you.
Weighing the Pros and Cons
| Pros | Cons |
|---|---|
| Lower repayments | Upfront fees: Discharge fees, application fees, break costs, and valuation fees |

Weigh the pros and cons when refinancing your home loan.
👉 More details in:
Does Refinancing Reset My Loan Term?
Yes, refinancing usually resets your loan to a full new term (e.g. 30 years).
But you can ask for a shorter term or make higher repayments to stay on track. This keeps you from paying more interest in the long run.

Alternatives to Refinancing
If refinancing isn’t ideal for your situation, you still have options to improve your loan setup.
Lowering Your Mortgage Payment Without Refinancing
Try these first:
- Some lenders offer repricing—where they give you a better rate without switching loans or reapplying.
- Reduce your repayment frequency
- Review your offset or redraw options
These tweaks might offer some relief without the hassle of refinancing.

Top-up Loans vs Refinancing
For smaller needs, a top-up loan might suit better than refinancing a home loan.
If you need extra cash, a top-up loan adds to your existing mortgage without changing the full loan.
It’s quick but may not have the best rate. If you’re borrowing a large amount, a cash-out refinance is usually better value.
