Key Takeaway

Refinancing your Australian home loan means switching to a new loan (often with a different lender) to secure a lower interest rate, access better features, or tap into your equity. Even a 0.5 per cent rate drop can save thousands in interest over the life of the loan. The process takes two to six weeks, but watch for break costs if you are leaving a fixed-rate loan early, and compare the total cost using the comparison rate, not just the advertised rate.

When Refinancing Makes Sense

Refinancing is worth considering when your current home loan rate sits well above the market average. According to ASIC MoneySmart, rate movements and competition among lenders mean you may find a better deal after holding your current loan for two or more years. If the Reserve Bank of Australia cash rate has shifted or new products offer offset accounts, redraw facilities, or lower fees, refinancing can align your loan with your current financial goals.

Other triggers include wanting to consolidate debt, switching from a fixed-rate loan to a variable-rate loan (or the reverse), or accessing equity for renovations or investment. The comparison rate, which factors in most fees and charges, is the clearest measure of true cost. As outlined in foundational finance texts such as Principles of Finance, the effective interest rate (which the comparison rate approximates) reveals the real repayment burden over time.

Steps to Refinance

Start by comparing offers from multiple lenders using a broker or comparison site like Finder. Request a refinance pre-approval to confirm serviceability (your ability to afford the new loan). Lenders assess your income, expenses, credit history, and the loan-to-value ratio (LVR) of the property.

Once approved, the new lender arranges a property valuation, prepares loan documents, and handles the discharge of your old loan. You sign the new contract, the settlement occurs, and the new loan pays out the old one. The whole process typically takes four to six weeks. Expect to pay an application fee (usually a few hundred dollars), a valuation fee, and possible discharge fees from your old lender. Some lenders offer cashback incentives (commonly A$2,000 to A$4,000) that offset these costs.

Watch for Break Costs and Fees

If you hold a fixed-rate home loan and refinance before the fixed period ends, the original lender may charge break costs (also called early exit fees or economic costs). These fees compensate the lender for lost interest and can run into thousands of dollars, especially if rates have fallen since you locked in. Variable-rate loans generally have lower or no break costs, but check your loan contract.

Add up all refinancing fees, the comparison rate of the new loan, and any break costs, then compare the total against your projected interest savings. If you save more than you spend within 12 to 24 months, refinancing usually makes financial sense. Rates as of August 2026 vary by lender and product, verify current terms with a licensed mortgage broker or lender before deciding, as advertised rates differ from comparison rates.

Next Step

Request a refinance quote from at least three lenders or speak with a licensed mortgage broker to compare your options. Run the numbers (new rate, fees, break costs) against your current loan to confirm the benefit. Once the savings are clear, lodge a formal application and let the new lender guide the discharge and settlement process.
