What hurts your credit score

Most of the advice that circulates about Australian credit scores is imported, outdated, or written to sell a monitoring subscription. The file is more boring than the folklore. Models differ across Equifax, Experian and illion, and lenders overlay their own decisioning. What they are all looking at, underneath the number, is a short list of behaviours and records. Missed payments. Defaults. Application enquiries. A thin or chaotic account mix. Public records. The rest is usually noise.

This is general information. It is not a direction to open, close or rearrange any credit contract. Credit Made Simple is not an Australian credit licensee. If a sentence starts to sound like a product instruction, ignore the implication and keep the mechanism.

The file is a record of behaviour, not character

A score is a compression of a file. How the scores are built matters because there is no single Australian number. How to read the report matters because the damage, when it is real, is a listing you can point to. This piece sits between those two: what kinds of listings actually move the models, and which kitchen-table myths do not.

Credit reporting in this country now includes comprehensive, or positive, information. The file is no longer only a museum of disasters. Monthly repayment history on participating consumer credit accounts is visible for a limited window. Limits and account types can sit alongside defaults. A person can hurt a score without ever attracting a collections listing, simply by paying late, often, on an account that reports. A quiet, on-time history is information too.

Missed payments and repayment history

Under comprehensive reporting, repayment history information is typically a month-by-month record covering about two years. Each month is a fact: whether that consumer credit account was paid as required, and if not, how overdue it was. One late month is a fact a human can explain. A run of late months is a pattern a model will not ignore.

This is the change people who last looked at a credit file in the 2000s underestimate. You no longer need a default for recent sloppiness to be visible. A card that is always twenty days late, and never late enough for collections to list a default, still leaves a grid.

If the reason you are late is that you cannot pay, the constructive move is not a score-optimisation project. It is the credit provider’s hardship process, and if necessary the rights in hardship variations under the National Credit Code. The National Debt Helpline on 1800 007 007 exists for that conversation.

Defaults

A default is a formal listing that an account was in default in the sense the Credit Reporting Code allows a credit provider to report. It is heavier than a late month. It is also more regulated than a collections letter. There are overdue and notice expectations around a listing. There are still listings that should never have been raised: the wrong person, a disputed amount, a debt already settled, a notice that never arrived because the provider had the wrong address.

Defaults stay visible for years, not months. Paying a default does not always remove it. It can change the status from unpaid to paid. That status change is worth making. It is not a wipe. If the default is not yours, that is a correction problem. If it is yours and you still cannot pay the underlying debt, that is a when you cannot pay problem.

Hard enquiries

An application enquiry is the bureau’s record that a credit provider looked you up because you asked for credit. Other credit providers can usually see those enquiries for years. A single enquiry for a product you actually wanted is ordinary life. A cluster — five car-dealer checks in a weekend, a string of card applications, a broker who sprayed your details — is a signal of hunger. Models treat recent hunger as risk. So do human assessors.

If you are approaching a home-loan application, reading the enquiry list first is not superstition. Shopping with a process that produces six visible enquiries, when one or two would have done, is how people arrive at a mortgage interview already looking busy.

The counterpart myth is that every glance at a file is an enquiry. It is not. Consumer access to your own information is a privacy right. Lender enquiries are commercial events. Apps that invite you to “check your eligibility” every fortnight are fishing for the second.

Utilisation, new accounts and thin files

American score folklore is obsessed with utilisation: the share of a card limit you are using. Australian comprehensive reporting made balances and limits more visible than they were in the negative-only years, so the relationship between what you owe on revolving credit and what you are allowed to owe is not irrelevant. A file that shows several cards pressed against their limits looks different from a file that shows one quietly used facility. That is a description of a pattern, not an instruction to shuffle balances around.

New accounts are similar. Opening a consumer credit account is an event. It creates an enquiry, it can change the mix and the available limits, and it resets the “how recently did this person go looking for credit” clock. A new account that is then paid as agreed becomes, with time, ordinary history. A new account that is one of four this quarter is part of a cluster.

None of that is a recommendation to keep a card, close a card, or take a card. Models notice recent appetite and stretched revolving limits. They do not award points for following a forum recipe.

A thin file is a shortage of Australian consumer credit history. Young adults have them. New arrivals have them. People who have lived on debit cards and paid rent in cash have them. The models have less to work with. That can look like a “low score”, or like a decisioning path that refuses to automate.

A thin file is not repaired by a burst of applications. That burst adds enquiries without adding much repayment history. Time, and a small number of accounts that are paid as agreed, is how files thicken. Building credit from scratch is the longer treatment. A secured card is sometimes discussed in this context; discussion is not a suggestion to apply.

Public records

Court judgments and personal insolvency information are not late-payment folklore. They are public-record facts with their own retention rules. A judgment says a court made an order. A bankruptcy or a debt agreement says something formal happened in the personal insolvency system. No monitoring app removes a current insolvency listing. If the record is wrong, that is a factual dispute with a paper trail. If the record is right, the constructive questions are about the underlying debt and the legal options, including debt agreements and bankruptcy.

Serious credit infringements — listings that go beyond an ordinary default, into alleged fraud or a concluded intention not to pay — are rarer and heavier. Treat one as a reason to get advice from a solicitor or a financial counsellor, not as a DIY score project.

Myths, and what usually does not matter as much as people think

Checking your own file does not hurt you. Repeating that sentence is tedious and still necessary, because the opposite claim is excellent for selling paid portals.

Changing address does not, by itself, “reset” or “damage” a score in the way missed payments do. An address is how the bureau knows which person it is talking about. A wrong address is how files get merged. Update it because you want the identity block to be true.

Being a homeowner, or not, is not a secret extra bureau category. Housing status can matter to a lender’s serviceability and security assessment. That is a different machine.

Closing every unused account on the same afternoon, or opening several small ones to “diversify”, is imported theatre. Australian files care about enquiries, repayment history, adverse listings and the length of useful history. They do not hand out gold stars for following a United States blog. A free score app that moves twenty points after you pay a phone bill is describing its own model, on its own refresh cycle.

Shopping around for insurance, or getting a quote that does not become a credit application, is not the same as six personal-loan enquiries. Job changes, by themselves, are not bureau events — though a lender will still ask about employment. Paying rent to a landlord who does not report will not, by itself, build the file you wish you had. It also will not usually stain that file. It is simply invisible.

Buy now pay later is a moving target, which is why it has its own piece. Do not assume a BNPL tile on a marketing site is a bureau listing. Do not assume the absence of a listing means a lender cannot see the repayments on your statements. The Commonwealth has been bringing BNPL into the credit regime.

Small-amount credit contracts — the old payday structure, still specially capped — can be expensive and can leave a mark if they go wrong. They are not a score strategy. They have their own cost cap (the classic 20 per cent establishment plus 4 per cent per month on the amount advanced). Using one to “build credit” is a confusion of categories.

What hurts a file, in ordinary Australian life, is unpaid and late consumer credit, formal defaults, a recent stack of applications, a missing history, and public records. What does not is curiosity about your own information, a change-of-address form, or a refusal to buy a weekly score subscription.

If the file is wrong, correct the listing. If the file is right and the debt is unpayable, deal with the debt. The number on the app will follow the file, or it will fail to match the lender’s number anyway. Either way, the file is the object.
