When you decide to take the plunge into the property market, your mind naturally floods with the big numbers. You think about the size of your deposit, your annual salary, and the price of that dream home.

But what if we told you that a single, almost invisible habit—something you do on your phone while sitting on the couch—could be silently chipping away at your ability to buy a home?

There is a massive misconception around how credit scores and “borrowing power” actually work in Australia. Today, we are busting the most common credit myths and exposing the tiny habit that is holding back everyday Aussies from achieving their property goals.

The Big Myth: “I Don’t Have Debt, So My Credit Score is Perfect”

Many prospective buyers believe that if they don’t owe thousands of dollars on a personal loan or have a roaring credit card balance, their financial profile is spotless.

In the lending world, having no debt does not automatically translate to a high credit score or maximum borrowing power. Under Australia’s Comprehensive Credit Reporting (CCR) system, lenders don’t just look at what you owe today; they look at your exact history of how you interact with credit lines over a rolling 24-month period.

Your credit score is a reflection of trust. If a bank looks at your file and sees zero history of managed credit, you are a blank canvas—and to a conservative risk assessment algorithm, a blank canvas can look surprisingly risky.

The Silent Killer: The “Just Browsing” Habit

So, what is the tiny habit that’s tanking your borrowing power? It’s the habit of indiscriminate credit clicking.

Think about how easy it is to shop online today. You see a pair of shoes or a new appliance, and at the checkout, you casually select a “Buy Now, Pay Later” (BNPL) service. Or maybe you’re shopping around for a new car loan, so you hit “Apply Now” or “Check My Rate” on three different comparison sites just to see what happens.

To you, this feels like smart consumer research. To a credit reporting agency like Equifax, every single one of those clicks can trigger a “hard enquiry” on your credit file.

How Hard Enquiries Squeeze Your Borrowing Power

Every time you formally submit an application for credit—whether it’s a $10,000 credit card, a phone contract, or a BNPL account—it leaves a permanent footprint on your credit history.

If a lender logs onto your file and sees four, five, or six hard enquiries spaced closely together, a red flag goes up. The algorithm doesn’t see a savvy shopper; it sees a borrower who might be under financial stress and desperately hunting for cash injection.

• The Result? Your credit score drops.
• The Knock-On Effect: Lenders reserve their absolute best interest rates for “excellent” credit tiers. A lower score can push you into a higher interest rate tier or cause a lender to heavily reduce the total amount they are willing to lend you. Just like that, your borrowing power takes a massive hit.

Other Credit Habits to Clean Up Before You Apply

If you want to maximize your borrowing capacity, you need to treat your credit file like a garden that needs regular weeding. Beyond stopping the casual credit applications, make sure you address these two major areas:

1. The Credit Card “Ghost” Limit

Did you know that if you have a credit card with a $10,000 limit, banks assess your borrowing capacity as if that card is completely maxed out—even if your balance is zero? Lenders must factor in the risk that you could spend that money tomorrow. Dropping your limits or cancelling unused cards is one of the fastest ways to give your borrowing power an instant boost.

2. The 5-Day Grace Period Oversight

With CCR, a late payment on a utility bill or mobile phone plan that drifts too far past the due date can be logged onto your credit report and stay there for two years. Automating your bills via direct debit is a micro-habit that shields your score from accidental human error.

The Verdict: Don’t Guess Your Borrowing Power

Navigating the hidden tripwires of credit scores doesn’t mean you have to figure it out alone. Navigating online calculators will only give you a generic, simplified estimate that doesn’t account for your actual credit behavior or specific lender policies.
