What Does It Actually Cost to Refinance a Home Loan in Australia?

Refinancing isn't free, but the fees are usually smaller than people expect — and smaller than the amount most established homeowners can save by getting their loan structured properly.

Here's exactly what you're likely to pay, and the one question that actually matters more than any of it.

The Costs You'll Actually See

Most refinance costs fall into two categories: what your current lender charges you to leave, and what your new lender charges you to join.

Neither is usually large enough on its own to make refinancing not worth it — but they add up, and it's worth knowing them before you compare rates.

The Costs You'll Actually See

  • Discharge fee: Typically $150–$450. This covers the administration of releasing the mortgage.
  • Fixed rate break costs: Only applies if you're leaving a fixed rate early. This can range from a few hundred dollars to several thousand, depending on how far rates have moved and how much time is left on the fixed term. Get this figure from your current lender before you commit to anything.
  • Government discharge fee: Around $100–$300, paid to your state's land titles office.

Entry costs (your new lender)

  • Discharge fee: Typically $150–$450. This covers the admin of releasing the mortgage.
  • Valuation fee: Frequently free with major and mid-tier lenders when refinancing; otherwise, $200–$300.
  • Mortgage registration fee: A government charge, typically $150–$250 depending on the state.
  • Lenders Mortgage Insurance (LMI): Only relevant if your equity has dropped below 80% of the property's value since you took out the original loan. This is the one cost that can genuinely change the maths — see what happens to LMI when you refinance for the full breakdown before you go further.

All up, most straightforward refinances land somewhere between $800 and $1,200 in direct costs if you're not breaking a fixed rate and not triggering LMI. That's the number worth anchoring to.

The Cost Question That Actually Matters

Fees are a known, one-off number. The real decision is whether the change is worth making at all — and that's not just about the interest rate.

A lower rate with a poorly structured loan can still cost you more over time than a slightly higher rate with the right splits, offset structure, and repayment strategy.

Before comparing costs against savings, it's worth asking three questions:

  • How long do I realistically plan to stay in this loan? (Costs matter less over a longer horizon.)
  • Am I refinancing to reduce repayments, access equity, or restructure — because each changes what "worth it" looks like.
  • Is my current lender's retention offer actually competitive, or just enough to keep me from checking?

A Realistic Example

On a $500,000 loan, moving from a rate that's 0.50% higher than market to a more competitive one saves roughly $2,500 in interest in the first year alone — against total refinance costs that typically sit around $800 to $1,200 when no fixed break or LMI is involved.

The break-even point in most cases is measured in months, not years. The exception is when a fixed-rate break fee or LMI is triggered — which is exactly why it's worth checking those two line items first, before assuming the maths works.

Work Out Your Actual Numbers

Every loan is different, and the fee estimates above are general ranges — not what you'll necessarily pay.

The only way to know your real break-even point is to look at your current loan, your equity position, and your goals together.
