Unsure whether to refix or refinance your mortgage? Learn the difference, when to act, and how timing can save thousands.

Understanding Refixing vs Refinancing

Many homeowners use refix and refinance interchangeably, but they mean very different things and the choice can make a big difference to your long-term costs.

Refixing means locking in a new fixed-rate term with your current lender when your existing term ends. It’s usually straightforward and doesn’t require a full application.

Refinancing means moving your loan to a different lender or restructuring your existing loan to access sharper rates or features like an offset or revolving credit account.

In simple terms:
Refix = stay with your lender.
Refinance = move to a new one.

How do interest rates fluctuations determine impact the decision to refix or refinance?

Since August last year, the Reserve Bank has eased policy several times, and the Official Cash Rate has fallen significantly, from a peak of 5.5 percent in July 2024 to 2.5 percent in October 2025.

As the OCR has fallen, so to have mortgage interest rates. Following the latest cut, which was larger than some had anticipated, it put pressure on lenders to stay competitive and we’re now seeing this flow through to mortgage rates, particularly at the shorter end of the curve. However, with rates expected to plateau and then potentially rise next year, the decisions you make about your mortgage over the coming months will be critical if you want to maxmise the potential for both short and long term savings.

What this means for your next mortgage decision

With rates falling, many banks offering cashback, and competition intensifying, the case for reviewing your loan structure (rather than simply rolling over) has strengthened.

• If your fixed term is expiring soon, it’s an ideal time to compare options and to look at whether refixing or refinancing will be more beneficial. From a rate perspective, it is likely to be better to still look at shorter terms of six or twelve months, as these may allow you to benefit if rates continue to ease through the rest of this year and in early 2026.
• If you’re mid-term on a higher rate, then it is definitely worthwhile speaking with your adviser to have them calculate whether breaking your term and refixing will make sense. Break fees can erode potential savings, but with the significant fall in interest rates over the past 12-months, the benefits may offset the cost.

Even if you’re not at renewal yet, reviewing your structure can still pay off. Many banks are actively competing for new clients, offering cashbacks, fee waivers, and even legal-cost coverage to attract refinance business.

So how do I decide whether to refix or refinance?

Refixing is a good choice when you’re happy with your lender, want simplicity, and your term is due to expire soon. It gives you certainty and helps you avoid rolling onto a higher floating rate.

However, refinancing can open better rates or loan features – it just might require a bit more effort. .

You might refinance if:

• Another lender offers a lower rate or a cashback that outweighs switch costs.
• You want to restructure to pay the loan down faster.
• You need equity for renovations, investment, or consolidation.
• Your financial position has improved since you drew the loan.

For example, the average one-year rate in October 2024 was 6.53 percent. If you had an $800,000 mortgage coming off this month, then you would be able to take advantage of a one-year rate of around 4.49 percent. This would mean your repayments would drop from about $5,072 to $4,049 per month – a saving of roughly $1,024 per month or around $61,400 over five years (based on a 30-year term). Add into the mix a potential cashback or cash retention payment and the savings could be significant.
