Why your credit score can look different elsewhere

Key points

• Australia has two credit reporting bodies, Equifax and Experian. Each holds its own file about you, uses its own scoring model, and receives information from a partly different set of credit providers.
• One person can hold two different credit scores on the same day, and both can be correct. A gap between two scores isn't evidence that one of them is wrong.
• The two scales are different, which means a number from one credit reporting body can't be read against a number from the other.
• illion's credit reporting body merged into Experian from 1 April 2026, and the calculation changed with it, so many Experian scores moved that year without anything changing in how those people were managing their money.
• The comparison worth making is a credit score against itself over time, from the same source. A change within one source is the part worth acting on.

You check your credit score in one place and see one number, then check somewhere else and see a number that's a long way off, and you may try to work out which one is wrong. Usually none of them are wrong. Two organisations can hold different information about you, run it through different models, publish the answer on different scales, and produce two numbers that are both accurate descriptions of what each one holds. So here we go through where the difference comes from, why the timing of the information accounts for a lot of it, and which number is actually worth watching.

Why are the numbers different?

Because Australia has two credit reporting bodies, and each one has its own scale, its own model and its own data (not every credit provider reports to both, so the files themselves differ). A credit reporting body collects credit information from providers, holds it as your credit report, and calculates a score from what it holds. Equifax and Experian each do that separately, and neither one sees the other's file.

Both credit reporting bodies also sort scores into bands, and each one uses its own band names with its own cut-offs. A band on one scale doesn't translate into the same band on the other, so a score of 700 doesn't mean the same thing in both places, and neither does the band name sitting next to it.

The data underneath is the other half of it. A credit provider decides which credit reporting bodies it reports to, and not all of them report to both, so an account, a credit enquiry or a repayment record that sits on one file may simply not be on the other. That isn't a fault in either file, it's how consumer credit reporting is set up in Australia.

One person can hold two different credit scores on the same day, and both of them can be correct.

Timing explains a lot of the rest

Credit providers send information to credit reporting bodies on their own cycles rather than the moment something happens. So an account you closed last month, or a repayment you made two weeks ago, may already show on one file while the other still shows the position as it was. Neither file is wrong when that happens, they're just describing different moments.

The score you're looking at works the same way. It was calculated from the information available when it was produced, so a number you saw last week and a number you're seeing today may have been built from different information even at the same credit reporting body. Two scores taken days apart aren't comparing the same information, before the difference in models is taken into account at all.

The 2026 change at Experian is the largest example of this. When illion's credit reporting body merged into Experian from 1 April, the information behind an Experian score and the calculation applied to it both changed, and plenty of people saw their number move as a result. If your Experian score shifted around then, the movement may have come from that change rather than from anything you did.

Which number should you actually use?

The one you can compare against itself – pick a source, stay with it, and watch which way it moves over time (comparing across the two credit reporting bodies tells you very little, because the scales and the models are different). A number on its own doesn't tell you much. The same score three months later, from the same place, tells you whether your position is improving.

In practice that means treating a change within one source as the signal worth acting on. If the score you follow drops, that's worth understanding. Where it drops in one place and holds steady in another, the first thing to check is whether the two are even describing the same file, because quite often they aren't. And checking a second source is completely fine, however it's worth treating that as a second file to review rather than a second opinion on the first.

Don't let a low number become a reason to do the wrong thing

A lower number in one place can become a reason to apply for something straight away, before the position gets worse. Formal credit applications are recorded as a credit enquiry or "hard check" and stay on your report for five years, and several applications close together can read as risky to a lender, regardless of why you made them. So if a score drop in one place is the only reason you're applying, the application is being made on information that may not describe your whole position.

The other reaction is to stop looking altogether. We hear from members that a number that looks bad becomes a reason not to check anything at all, so nothing gets reviewed, nothing gets corrected, and the position sits unexamined for months. That reaction rests on a misunderstanding.

Looking at your own credit report or credit score is not an application for credit. You can check your own report as often as you like without affecting your score, and what you look at isn't shown to credit providers assessing you later.

Pro tip: WeMoney only ever does soft checks, never hard checks. So checking where you stand does no damage to your credit file, and leaves no hard checks a lender can see.

What consolidating or applying actually does to a credit report is a separate question, and it's worth reading up on before an application rather than after one. The same goes for checking a credit score without affecting it, which has its own detail worth going through.

And if the information behind the number looks wrong rather than merely different, that's a different job again. An account you don't recognise, a repayment marked as missed when it wasn't, or a credit enquiry you never made, all have a correction route, and it's free to use. Working out why a score changed, and reading what your repayment history actually records, both have their own places to be worked through properly.

So pick one place to watch your score, look at it every few months rather than every few days, and pay attention to the direction it's moving rather than the number itself. You can follow it in WeMoney alongside the accounts and repayments behind it, which makes a movement much easier to explain when one turns up. Collecting numbers from several places feels thorough, however it can produce a spread you can't interpret and a decision made on the shakiest information available.
