Mortgage Refinancing: Is Switching Lenders Worth It Right Now?
Interest rates in Australia went up three times this year. Not down. If your home loan is more than a year or two old and you haven't touched it since settlement, there's a fair chance your bank is charging you more than it offers some new borrowers today. Mortgage refinancing means replacing your current home loan with a new one, ideally at a rate, structure, or lender that suits where you are now, not where you were when you signed. At Noor Finance, we run that comparison across a panel of more than 50 lenders and, wherever your situation allows it, we keep the paperwork to what a lender genuinely needs rather than what's simply "standard".
What's Driving Mortgage Refinancing Right Now
The Reserve Bank held the cash rate at 4.35% in June 2026, after three increases earlier in the year pushed it there. You'd think that would slow refinancing down. It hasn't. Owner-occupiers switched close to $43 billion worth of loans to new lenders in the March 2026 quarter alone, according to ABS data, near a record for that measure. The gap between what new customers are offered and what existing customers remain on has never really closed. Banks compete hard for new business and do very little, unprompted, for the loan you signed three or five years ago.
Canstar's analysis of the same ABS figures gives a sense of scale: a borrower who took out a loan five years ago and hasn't renegotiated since could still be sitting on a variable rate above 7%. Refinancing to something closer to 6% on a 600,000 loan could save well over 11,000 across two years. That's a general market illustration, not a promise, since your actual saving depends on your rate, loan size, and lender. But it's the kind of gap worth checking rather than assuming your current deal is still competitive.
There's a real downside too: APRA's service ability buffer still requires lenders to test new applications at your rate plus 3 percentage points, which has left a genuine number of borrowers unable to refinance externally even though a cheaper rate exists elsewhere. Brokers sometimes call this "mortgage prison." It's a real constraint, not a scare tactic. It's exactly the kind of thing worth checking with a broker before you assume refinancing either will or won't work for you.
What Refinancing Can Change
Refinancing isn't just about chasing a lower headline rate, even though that's usually the starting point. Depending on your situation, it can also let you:
- Switch from a variable rate to fixed, or the other way around, as your risk appetite or plans change
- Release equity for renovations, a second property, or something else entirely
- Consolidate credit cards, car loans, or other debt into your mortgage at a lower blended rate
- Shorten your loan term so you own the place outright sooner, or extend it to free up monthly cash flow
- Move to a lender that offers a feature yours doesn't, like a proper offset account

Easy Refinance Options When Your Income Doesn't Look Like a Pay slip
This is where most of the anxiety around refinancing sits. If you're self-employed, a company director, or your income runs through a trust or multiple ABNs, the idea of gathering two full years of tax returns and notices of assessment just to refinance a loan you already have can feel like more trouble than it's worth. It's also the exact scenario where good tax planning works against you: a trade earning 180,000 a year might have a tax return showing 90,000 after legitimate deductions, and a mainstream bank will assess the smaller number.
Low-doc and alt-doc lending still exists. It's just more clearly regulated than it was before 2008. "No-doc" loans, where you simply declared your income, don't exist anymore; every lender still wants evidence. But that evidence can be your last six to twelve months of Business Activity Statements (BAS), business bank statements, or a letter from your accountant confirming your actual trading position, rather than a full personal and business tax return package. For a straightforward refinance (same loan amount, an established repayment history, no major changes to your circumstances), some lenders may be able to assess an easy refinance with minimal documentation. It still comes down to the individual lender's policy and your specific file, which is exactly what a broker checks before you apply anywhere.
Our low doc home loans and self-employed loans pages go into more detail on which lenders on our panel are genuinely flexible here, because it varies more between lenders than most people expect.
What Switching Costs
Lender exit fees were banned on all new home loans from 1 July 2011, so if your current loan was written after that date, you won't be charged a penalty simply for leaving. What can still apply: a discharge fee (typically 150-500) to close out the old loan, a break cost if you're on a fixed rate and leaving before the term ends, and Lenders Mortgage Insurance if your new loan sits above 80% of the property's value. There's also the standard valuation and settlement cost any new loan carries.
None of that should be a mystery going in. A proper cost-benefit comparison (including the comparison rate, not just the headline rate) is the first thing we work through with you before recommending anything.
If you're refinancing out of an interest-based loan altogether and want to move towards a Shariah-compliant structure instead, that's a separate conversation worth having early. Our halal home loan page explains how that works in practice.
Is Refinancing Worth It for You?
Refinancing makes sense for a lot of homeowners right now, and it makes no sense at all for some. The only way to know which camp you're in is to run your current loan against what's on offer today. Bring your most recent loan statement and either your last two pay slips or your BAS if you're self-employed. Our founder Ali can review your current loan, income documents, and goals, then explain whether refinancing may be worth pursuing.
