What Is Refinancing? The Complete Australian Guide | Broker360

Refinancing your home loan can save thousands in interest, reduce monthly repayments, or unlock equity for your next goal. Yet many Australian borrowers stay on outdated rates because they do not understand the process, costs, or whether it makes sense for their situation. With the RBA cash rate at 4.10 per cent in 2026 and lender competition intensifying, refinancing activity has reached record levels. This guide explains exactly what refinancing is, how it works, what it costs, and how to calculate whether the savings justify the switch. Whether you are looking to lower your rate, consolidate debt, or access equity, you will find clear, actionable answers here.

What is refinancing a home loan

Refinancing means replacing your existing home loan with a new loan, either from your current lender or a different one. The new loan pays out your old loan in full, and you begin making repayments under the new terms.

Borrowers refinance for several reasons:

• Lower interest rate: Reduce monthly repayments and total interest paid over the loan term
• Access equity: Borrow against the portion of your property you own outright
• Consolidate debt: Roll multiple high-interest debts into your home loan at a lower rate
• Switch loan types: Move from variable to fixed rate or vice versa for better financial stability
• Improve features: Add an offset account, redraw facility, or other beneficial features

Example: If you currently have a $500,000 home loan at 5.8 per cent and refinance to a new loan at 5.2 per cent, you could save approximately $2,500 annually in interest repayments.

Refinancing applies to home loans primarily, though car loans and personal loans can also be refinanced. This guide focuses on home loan refinancing as it represents the largest financial decision most Australians make.

How refinancing works step by step

The refinancing process follows a clear sequence. Understanding each step helps you prepare and avoid delays.

1. Assess your current loan: Review your interest rate, remaining balance, fees, and any fixed rate expiry dates. Obtain a copy of your loan contract and recent statements.
2. Check your borrowing capacity: Use a borrowing power calculator or speak with a broker to understand how much you can borrow under current serviceability rules.
3. Compare loan options: Research lenders and products. Consider interest rates, fees, features, and lender policies. A mortgage broker can scan 30 plus lenders on your behalf.
4. Submit application: Complete the application with your chosen lender. Provide income verification, bank statements, identification, and property details.
5. Property valuation: The new lender orders a valuation. Many refinances use desktop valuations that require no physical inspection.
6. Receive approval: Once the valuation and assessment are complete, you receive formal approval with loan terms.
7. Settlement: Your new lender coordinates with your old lender to pay out the existing loan. The mortgage discharge registers electronically, typically within 21 to 30 business days from application.
8. Begin new repayments: Start making repayments under your new loan terms. Set up direct debits and any linked offset or redraw accounts.

Timeline: Most refinances complete within 4 to 6 weeks. Broker-assisted refinances often settle faster due to streamlined document collection and direct lender relationships.

What does refinancing actually cost

Refinancing involves several potential costs. Understanding each one helps you calculate whether the switch makes financial sense.

Variable rate loans: If you are on a variable rate, you will not pay break costs. Your total switching costs typically range from $300 to $800 including discharge and any application fees.

Fixed rate loans: Break costs apply only if you exit before the fixed term expires. Break costs are calculated based on the interest rate differential between your fixed rate and current wholesale rates, multiplied by your remaining term. These can range from a few hundred dollars to $15,000 or more on large loans with significant rate differences.

Important: Your current lender must provide a written break cost estimate before you commit to breaking a fixed term. Never rely on verbal quotes. Request this in writing and factor it into your decision.

The break-even calculation

The break-even point tells you how many months it takes for your refinancing savings to exceed your switching costs. This is the most important calculation in your refinancing decision.

Break-even formula:

Example 1: Variable rate refinance with no break costs

• Current loan: $500,000 at 5.8 per cent
• New loan: $500,000 at 5.2 per cent
• Monthly interest saving: $250
• Switching costs: $350 discharge fee plus $200 application fee equals $550
• Break-even: $550 divided by $250 equals 2.2 months

This is a clear win. You recover your costs in just over 2 months, then save $250 every month after that.

Example 2: Fixed rate refinance with break costs

• Current loan: $600,000 at 4.2 per cent fixed, 18 months remaining
• New loan: $600,000 at 5.4 per cent variable
• Monthly interest increase: $600 (you would be worse off)
• Break costs: $8,500
• Break-even: Never (you lose money)

This refinance does not make sense. You would pay more in interest plus $8,500 in break costs. Wait until the fixed term expires.

Example 3: Fixed rate nearing expiry

• Current loan: $550,000 at 6.1 per cent fixed, 3 months remaining
• New loan: $550,000 at 5.3 per cent variable
• Monthly interest saving: $367
• Switching costs: $400 discharge fee (no break costs in final 3 months)
• Break-even: $400 divided by $367 equals 1.1 months

This makes sense if your fixed rate expires soon. Many lenders waive break costs within the final 3 to 6 months of a fixed term.

Rule of thumb: If your break-even point exceeds 24 months, refinancing typically does not make sense unless you plan to stay in the property long term. If break-even is under 12 months, refinancing is usually worthwhile.

When should you refinance (And when should not you)

Refinancing makes sense in specific situations. It does not make sense in others. Use this framework to evaluate your position.

When refinancing makes sense:

• Rate differential exceeds 0.35 per cent after accounting for all costs
• Break-even point is under 18 months
• Your fixed rate expires within 6 months
• You need features your current loan lacks (offset account, flexible redraw)
• You want to consolidate high-interest debt above 8 per cent
• Your lender relationship has deteriorated (poor service, unexpected fees)

When refinancing does not make sense:

• Break costs exceed 18 months of potential interest savings
• You plan to sell the property within 12 months
• Your current rate is already market-leading (below 5.5 per cent variable in 2026)
• Refinancing triggers LMI that erodes net benefit
• You would fail serviceability assessment under current APRA buffer rules

Strategic insight: Refinancing is a strategic tool, not a universal solution. The goal is not to refinance frequently, but to refinance strategically when genuine value exists.

Common refinancing myths debunked

Misconceptions about refinancing prevent many borrowers from making informed decisions. Here are the five most common myths and the facts.

Myth 1: Refinancing always saves money

Fact: Refinancing only saves money when the net present value of future savings exceeds total switching costs. A borrower with $8,500 in break costs accessing a rate only 0.4 per cent lower may be worse off for years. Always calculate your break-even point before proceeding.

Myth 2: You need perfect credit to refinance

Fact: Perfect credit is not required. Minor defaults under $150 paid within 90 days, single late payments in the past 12 months, and even discharged bankruptcies after 3 to 5 years can still access refinancing options. Current repayment capacity matters more than historical blemishes.

Myth 3: Refinancing resets your entire loan term

Fact: You maintain complete control over your repayment timeline. You can request the new loan match your remaining term (for example 25 years instead of restarting at 30 years) or even accelerate payoff. Explicitly state your preference during application.

Myth 4: My current lender will match any competitor offer

Fact: Lenders occasionally match rates for valuable customers, but this is not guaranteed. New customers often receive better deals than existing borrowers. Always obtain a written competitor offer before negotiating. Without concrete alternatives, retention teams lack incentive to deliver genuinely competitive terms.

Myth 5: You must have 20 per cent equity minimum

Fact: Refinancing remains possible below 80 per cent LVR. Most lenders permit refinancing with LMI capitalised into the loan amount up to 90 to 95 per cent LVR. However, factor LMI costs explicitly into your break-even calculation. For marginal rate improvements, waiting until you reach 80 per cent LVR often proves financially superior.

Ways to use refinancing

Refinancing serves multiple purposes beyond lowering your interest rate. The right strategy depends on your financial goals.

1. Lower your interest rate: The most common reason. Even a 0.5 per cent reduction on a $500,000 loan saves $2,500 annually.

2. Consolidate debt: Roll multiple high-interest debts (credit cards at 18 to 22 per cent, personal loans at 10 to 15 per cent) into your home loan at 5 to 6 per cent. This simplifies repayments and reduces total interest costs. Learn more in our dedicated guide: Refinancing for Debt Consolidation.

3. Access equity: Borrow against the portion of your property you own outright. Use funds for renovations, investment property deposits, or major expenses. Equity release requires careful structuring for tax efficiency. Learn more in our dedicated guide: Refinancing for Equity.

4. Switch loan types: Move from variable to fixed for certainty, or fixed to variable for flexibility. Some borrowers split their loan across both types to hedge against rate movements.

5. Improve loan features: Add an offset account, unlimited redraw, or flexible repayment options. Feature improvements can deliver value beyond rate reductions alone.

6. Remove cross-collateralisation: If multiple properties are secured against one lender, refinancing can separate them into standalone loans, giving you flexibility to sell or restructure individual assets without bank permission.

Australia’s refinancing market in 2026

Understanding current market conditions helps you time your refinance strategically. Here is the national refinancing landscape as of April 2026.

RBA cash rate: 4.10 per cent following two consecutive hikes in early 2026. The next RBA board meeting is scheduled for May 2026.

Rate dispersion: The difference between the lowest and highest variable rates for identical borrower profiles reached 1.65 percentage points in January 2026. This creates significant opportunity for borrowers on outdated rates.

Refinancing volume: $65.8 billion in home loans refinanced during the September 2025 quarter, a record-breaking figure according to ABS data. Refinancing activity remains elevated as borrowers seek relief from rising repayments.

Lender competition: Non-bank lenders now represent 24 per cent of new residential lending, driving aggressive pricing for borrowers with clean credit histories. Major banks have responded with retention offers and cashback incentives ranging from $2,000 to $4,000.

Serviceability: APRA’s 3 per cent serviceability buffer remains in effect. Lenders assess your ability to repay at your actual rate plus 3 per cent. This affects borrowing capacity more than interest rates alone.

Average refinancing saving: Nationally, borrowers who refinanced in 2025 saved an average of $3,200 annually in interest repayments. Western Australian borrowers saved slightly more ($3,600 average) due to stronger property appreciation creating equity buffers.
