Choosing the length of a fixed rate term involves more than picking the lowest rate on offer.
The term you lock in determines how long you're protected from rate rises, how much flexibility you retain, and what happens when that fixed period ends. A two-year fixed rate might offer the lowest initial rate, but a longer term could provide more certainty if you value stability over savings. Your decision depends on whether you expect to sell, refinance, or access equity before the fixed term expires.
What a Fixed Rate Term Actually Locks In
A fixed rate term locks in your interest rate for a set period, usually between one and five years. During that time, your repayments remain unchanged regardless of movements in the variable rate market. The fixed term begins at settlement and ends on the agreed date, at which point your loan typically reverts to the lender's standard variable rate unless you choose another fixed term or refinance.
Consider a scenario where someone purchasing in Camberwell locks in a three-year fixed rate at settlement. For the next three years, their repayments remain constant. If variable rates rise during that period, they continue paying the lower fixed rate. If variable rates fall, they remain locked in at the higher rate. At the end of the three years, the loan reverts to the variable rate unless they act before expiry. The term you choose determines the length of that protection and the length of that constraint.
Most lenders allow you to make extra repayments on a fixed rate loan, but only up to a certain limit each year, often around $10,000 to $30,000 depending on the lender and loan structure. If you exceed that limit, break costs apply. If you sell the property, refinance, or pay out the loan entirely before the fixed term ends, break costs could also apply depending on how far rates have moved since you locked in.
Two-Year Fixed Terms: Lower Rates, Less Commitment
Two-year fixed terms typically offer the lowest fixed rates available. Lenders price shorter terms more competitively because they carry less long-term risk. If you expect to sell, upgrade, or refinance within a couple of years, a two-year term gives you rate protection without locking you in beyond your likely horizon.
In our experience, buyers in Camberwell who are purchasing an apartment as a stepping stone before upgrading to a larger home often favour a two-year fixed term. They get the certainty of fixed repayments without the exposure to break costs if they sell within that timeframe. The downside is that two years pass quickly, and when the fixed term expires, you're back to managing rate movements sooner than you would be with a longer term.

If variable rates rise sharply in year three, you're exposed. If you intended to refinance to a lower rate before expiry but miss the window, you could end up on a higher revert rate until you take action. Shorter terms require more active management.
Three and Four-Year Terms: The Middle Ground
Three and four-year fixed terms balance rate competitiveness with a longer period of certainty. Rates on these terms sit slightly higher than two-year fixes but lower than five-year locks. They suit borrowers who want protection beyond the immediate term but don't want to commit to a full five years.
If you're buying in a suburb like Camberwell where property values have historically appreciated steadily, and you intend to hold the property for the medium term, a three or four-year term gives you breathing room. You're not constantly monitoring rate movements, and you're not locked in so long that life changes become difficult to accommodate.
The trade-off is that rates on three and four-year terms don't offer the rock-bottom pricing of a two-year fix, and they don't provide the extended certainty of a five-year term. You're in the middle, which works well if your circumstances align with that timeframe, but less so if you're trying to optimise for either cost or certainty at the extremes.
Five-Year Fixed Terms: Maximum Certainty, Highest Rate
Five-year fixed terms offer the longest period of rate protection available in the Australian market. Your repayments remain unchanged for five full years, which provides certainty for household budgeting and insulates you entirely from rate volatility during that period. The cost is that five-year fixed rates are typically the highest of all fixed terms, and you're committing to that rate for a long stretch.
If you're confident you'll stay in the property, won't need to access equity, and value certainty above all else, a five-year term removes rate risk from your financial planning. But if circumstances change and you need to sell, refinance, or access equity before the five years is up, break costs on a five-year fixed loan can be significant, particularly if rates have fallen since you locked in.
Lenders calculate break costs based on the difference between your fixed rate and the current wholesale rate for the remaining term. On a five-year fix with three years remaining, that calculation can produce a substantial cost if the market has moved against you. It's not a reason to avoid five-year terms, but it is a reason to be certain about your plans before committing.
Split Loans: Fixing Part, Not All
You don't have to fix your entire loan. A split loan structure allows you to fix a portion of your borrowing while keeping the rest variable. You might fix 50% for three years and leave 50% variable, or fix 70% for two years and keep 30% on variable. The split gives you some protection from rate rises while retaining flexibility on the variable portion.
In a scenario where someone buying an investment property in Camberwell wants certainty on most of their repayments but also wants the ability to make unlimited extra repayments or access an offset account, a split structure works well. They fix the majority of the loan to stabilise cash flow and keep a smaller portion variable to retain those features. The variable portion also acts as a buffer if they need to access equity or pay down the loan faster without triggering break costs.
Split structures do require you to choose a fixed term for the portion you're locking in, so all the same considerations about term length apply. The difference is that you're only applying them to part of your borrowing, which reduces the stakes if you get the timing wrong.
What Happens When Your Fixed Term Ends
When your fixed rate term expires, your loan reverts to the lender's standard variable rate unless you take action. That revert rate is typically higher than the lender's advertised discounted variable rate for new borrowers. If you do nothing, your repayments could increase significantly.
Most lenders contact you 30 to 90 days before your fixed term ends to offer you the option to refix or switch to a different product. At that point, you can choose another fixed term, move to a variable rate, or refinance to another lender entirely. The key is to act before expiry, not after.
If you're planning to refinance at the end of your fixed term, allow at least six to eight weeks for the process. Applications, valuations, and settlement all take time, and if your fixed term expires before your refinance settles, you'll spend some period on the higher revert rate. Planning ahead avoids that gap.
How to Choose the Right Fixed Term for Your Situation
Start with your expected holding period. If you're likely to sell or upgrade within two to three years, a longer fixed term introduces unnecessary risk of break costs. If you're planning to hold the property long-term and value certainty, a longer term makes sense.
Consider your need for flexibility. If you expect a windfall, inheritance, or bonus that you'd like to put toward the loan, a variable rate or split structure gives you more room to make extra repayments without penalty. If your income is stable and predictable, and you'd rather set and forget, a fixed term with modest extra repayment allowances could work well.
Think about the rate environment. If variable rates are rising or expected to rise, locking in a fixed rate now provides protection. If rates are falling or stable, a shorter fixed term or variable rate keeps your options open. You're not trying to pick the market perfectly, but you should have a view on whether you're locking in at a reasonable point in the cycle.
For clients in suburbs like Camberwell, where property values support strong borrowing capacity and buyers often move through the market progressively, we regularly see split structures with a two or three-year fixed component. It's not the only approach, but it tends to suit buyers who want some certainty without locking themselves in beyond their likely horizon.

Frequently Asked Questions
What is the difference between a two-year and five-year fixed rate term?
A two-year fixed term typically offers a lower interest rate but provides protection for a shorter period. A five-year term locks in your rate for longer, giving you more certainty, but usually at a higher rate and with greater exposure to break costs if you need to exit early.
What happens when my fixed rate term expires?
When your fixed term ends, your loan reverts to the lender's standard variable rate unless you choose to refix, switch to a discounted variable rate, or refinance. Most lenders notify you 30 to 90 days before expiry so you can take action before the revert rate applies.
Can I make extra repayments on a fixed rate loan?
Most lenders allow limited extra repayments on fixed rate loans, often between $10,000 and $30,000 per year depending on the lender. If you exceed that limit, break costs may apply. A variable rate or split loan structure offers more flexibility for larger extra repayments.
What are break costs on a fixed rate home loan?
Break costs are fees charged by the lender if you pay out, refinance, or sell your property before the fixed term ends. They're calculated based on the difference between your fixed rate and the lender's current wholesale rate for the remaining term. Break costs can be significant if rates have fallen since you locked in.
Should I fix part of my loan or all of it?
A split loan allows you to fix a portion of your borrowing while keeping the rest variable. This gives you some protection from rate rises while retaining flexibility on the variable portion for extra repayments or offset account access. The right split depends on your need for certainty versus flexibility.
