Your Australian credit score while overseas: keep the file alive

Your Australian credit file doesn't freeze when you leave. It slowly goes quiet, and a quiet file is not what a lender wants to see when you come back for a home loan.

The short version

• Australia now has two main credit reporting bodies, Equifax and Experian. illion's consumer bureau merged into Experian from 1 April 2026 [1].
• Lenders see only the last 24 months of your monthly repayment history [2]. Close everything when you leave and that record runs dry.
• One small, forgotten bill can become a default that sits on your file for five years [3].
• Credit history built overseas doesn't transfer to Australia, and your Australian history doesn't travel with you either [4].
• You can check your report free every three months from each bureau, from anywhere with internet [5].

How Australian credit reporting works now

A credit report is the record. A credit score is a number a bureau calculates from it. Lenders use both.

Your report holds your identity details, the credit accounts you've held, their limits and open and close dates, your monthly repayment history, any defaults, hardship arrangements, court judgments and insolvency, and a list of who has looked at your file [3]. Scores run from 0 to 1,000 or 0 to 1,200 depending on the bureau, and a higher score means a lender sees you as less risky [3]. Equifax, for example, uses 0 to 1,200 [4].

Australia uses comprehensive credit reporting. That means "positive" data is recorded too: not just the times you missed a payment, but the months you paid on time [2]. Banks, credit unions and licensed finance companies report repayment history. Phone, internet, gas and electricity accounts don't report repayment history [2].

One bureau fewer in 2026

Until this year there were three bureaus. From 1 April 2026, illion and Experian became a single Experian bureau, so lenders checking your "Experian" report now see a combined file [1]. Some lender letters may still say illion for a while. If your Experian score shifted around April, that's not unusual, because the scoring calculation changed; a big jump is still worth a look at the report itself [1].

What happens to your file while you're away

Here's how long each type of information stays, according to Equifax [6]:

Put that together and you can see the problem. Say you close your credit card and pay off your car loan before you move to London. Two years later, those accounts drop off. Your repayment history is already gone. You come home after four years with a file that shows your name and old addresses, and not much else. Your London credit history doesn't help, because overseas history doesn't transfer into Australian reporting [4].

A thin file isn't a black mark. But it gives a lender less to go on, right when you're asking for the biggest loan of your life.

How to keep your file healthy from overseas

Keep one account ticking over

The simplest move is to keep one Australian credit product open and in use:

1. Choose a low-limit credit card. Lenders can treat a large limit as potential debt even if you never use it, so smaller is better [7].
2. Put one small regular charge on it. A streaming subscription or an insurance premium is enough to create monthly activity.
3. Set a direct debit for the full balance from your Australian bank account, so it's paid on time every month without you remembering.
4. Make sure the account can live with you being overseas. Before you go, tell the bank you're moving and check that it's happy to keep the card open with an overseas address. Policies differ between banks and products, so ask rather than assume.

If you keep an Australian mortgage on a property you rent out, that loan already builds repayment history every month. Make sure the repayments come from an account that always has money in it.

Close the small stuff properly

The default that wrecks an expat's file is almost always something tiny: a final electricity bill, the last month of a phone contract, a gym membership, a toll account. A provider can list a default for an unpaid debt of A$150 or more once it's 60 days overdue, as long as it has notified you [3]. If the notice goes to your old address, you'll never see it.

Before you leave:

• Close utility, phone, internet and subscription accounts in writing, and ask for a final bill.
• Pay final bills by direct debit or card, not by "I'll sort it when I get there".
• Give every remaining provider an email address and an overseas or trusted Australian postal address.
• Keep your Australian mobile number alive if your bank or lenders use it for security codes.

A default stays for five years even after you pay it; the report will simply show it as paid [3].

Check your report every few months

You're entitled to a free copy of your credit report every three months from each bureau, plus another free one if you've been refused credit in the past 90 days [5]. Experian's consumer report is available online after you answer a few identity questions [8]. Put a reminder in your calendar for each quarter and check:

• addresses and personal details
• accounts you don't recognise
• enquiries you didn't make
• defaults, especially from old utility or phone accounts

Correcting a genuine error is free. Only wrong information can be removed, so be wary of anyone charging to "repair" your file [3]. If you suspect fraud, you can ask the bureaus to place a temporary ban on your file [3].

Why it matters when you buy back home

Any Australian lender will pull your credit report when you apply for a home loan, whether you apply from abroad or after you land. What they want to see:

• Recent, clean repayment history. That's the 24-month window [2].
• Few recent applications. Each one is an enquiry that sits on the file for five years [6]. Applying to five banks in a fortnight looks like desperation, even when it's just shopping around.
• Modest existing limits. Unused credit card limits can count against how much you can borrow [7].
• No defaults. One unpaid phone bill can turn a straightforward application into a hard one.

Your foreign income, deposit and residency status matter at least as much as the credit file, and expat lending has its own rules. We cover those in the property section. The credit file is the bit you can quietly look after from day one, at almost no cost.
