How Often Can You Refinance Your Home Loan in Australia?

There’s no legal limit on how often you can refinance your home loan in Australia. Technically, you could refinance as soon as your current loan settles. But just because you can doesn’t mean you always should – and understanding the difference is where real savings are made.

So, how often can you refinance your home loan, and when does it actually make sense to do it?

Key Takeaways:

• There is no legal limit on how often you can refinance your home loan in Australia
• Most borrowers benefit from reviewing their loan annually and refinancing every 2–3 years
• Refinancing costs money upfront – those costs need to be weighed against potential savings
• Refinancing too frequently can affect your credit file
• A mortgage broker can help you assess whether the timing is right for your situation

How Often Can You Refinance a Home Loan in Australia?

There are no hard rules around the number of times you can refinance your home loan in Australia. Essentially, you just need to meet the lender’s credit requirements to be approved.

That said, a few practical factors can shape how refinancing can make sense:

• Fees add up. Every refinance involves costs – discharge fees on your current loan, establishment fees on the new one, and potentially a property valuation fee.
• Your credit file takes a hit (temporarily). Each application triggers a credit enquiry, and too many in a short period can affect your score.
• Some lenders have waiting periods. It’s worth checking your current loan terms before assuming you can switch freely.

It’s generally best to review your home loan once a year and consider refinancing every 2–3 years. That rhythm gives enough time for meaningful savings to accumulate – and enough market movement to make the switch worthwhile.

How Often Should You Refinance Your Mortgage?

Many people wonder how often they should refinance their mortgage. But the answer really depends on whether it genuinely puts you ahead.

Refinancing every six months might sound like savvy money management, but the maths rarely stacks up. You’re paying exit and entry fees each time, adding enquiries to your credit file, and spending weeks in paperwork – all for savings that might take years to recoup.

Refinancing more than once within 6–12 months is generally too frequent unless there is a significant financial benefit.

On the other hand, leaving a loan untouched for five or six years without reviewing it is how many Australians end up paying a loyalty tax – sitting on a rate that’s well above what the market offers to new customers.

The sweet spot for most borrowers is a proper review every 12 months and a serious refinancing conversation every 2–3 years. That’s when it’s worth checking whether your rate is still competitive, whether your fixed or variable home loan structure still fits, and whether your loan features match your current life.

What Does Refinancing Actually Cost?

This is the number most people underestimate. According to data from Canstar, taking out a new mortgage in Australia can cost anywhere from $750 to $2,108, depending on your loan refinance terms.

That range is wide, but the fees you’re most likely to encounter include:

• Mortgage registration fee, charged by the state government
• Discharge fee, charged by your current lender to close the loan
• Break costs if you’re leaving a fixed-rate loan early – these can be substantial
• Establishment/application fee charged by your new lender
• Property valuation fee, required to assess your current LVR
• Lenders Mortgage Insurance (LMI), payable again if your equity has dropped below 20%

Understanding your loan-to-value ratio (LVR) matters here. If you’ve built up solid equity, you’re in a much stronger position to refinance without triggering additional costs. If your LVR is still above 80%, you may need to factor in Lenders Mortgage Insurance on top of everything else.

The key question is simple: do the long-term savings outweigh the upfront cost? A good mortgage broker will run the numbers with you before you commit to anything.

When Does Refinancing Make Sense?

These are some of the situations where switching could deliver real value:

1. Your rate is no longer competitive. Lenders routinely offer sharper rates to new customers than they give existing ones. If you feel the current interest rate on your home loan isn’t competitive, it may be time to refinance.Many Australians are avoiding home loan rip-offs by reviewing their mortgage regularly rather than assuming their bank will pass on rate cuts automatically.
2. Your fixed-rate term is ending. When your fixed-rate term ends, your loan typically reverts to your lender’s standard variable rate, which is often much higher than the most competitive rates available. That’s a natural trigger point to shop around.
3. Your financial situation has improved. A higher income, lower debt levels, or an improved credit score can open the door to better loan terms than you qualified for originally.
4. You want to access equity. Refinancing lets you access equity to fund a renovation, take a holiday, or even buy another property.
5. You want to consolidate debt. Rolling high-interest debt into your mortgage can simplify repayments and reduce overall interest costs – though it’s worth getting advice before doing this, as you’re spreading short-term debt over a longer loan term.

When Refinancing Might Not Be Worth It

Not every situation calls for a switch. If you plan on selling your home in the next year or so, refinancing may not be an ideal choice – you might not stay in the loan long enough to recover the upfront costs.

Similarly, if your income has recently dropped, you’ve taken on new debt, or your LVR has worsened, lenders may offer you less competitive terms than you’re expecting – or decline the application altogether.

Refinancing frequency also matters from a lender’s perspective. Switching every few months can raise flags, as it may signal financial instability to new lenders assessing your application.
