The credit limit change process

Credit limit increases

For credit card limit increase requests, you’ll be asked to provide information on:

  • current employment
  • income (before and after tax)
  • assets, liabilities and expenses.

This will include providing proof of income documentation (e.g pay slips). We use this information to make sure the increased credit limit suits your circumstances.

We’ll then verify the information and assess your request. That usually takes a few days.

Once we've done an assessment, we may need to call you for more information or check the information you already gave us. We'll do our best to let you know the outcome within a week.

Credit limit decreases

You can decrease your credit limit instantly using the NAB app or NAB Internet Banking. If you visit your local branch or call us to request the change, this may take longer.

If you’re decreasing your credit limit, you can't go any lower than your current outstanding balance or the minimum product limit:

  • Signature cards: $15,000
  • Platinum/Premium cards: $6,000
  • other cards: $1,000.

Who can change a credit limit

A credit card account only has one credit limit which applies to all cards and cardholders. Only the primary cardholder can apply to change the credit limit of their credit card account.

Changing a business credit card limit

If you have a business or corporate card, you can contact the Corporate and Business Servicing team.

Or speak to your relationship manager, if you have one.

Tips to manage your credit limit

Your credit card offers great flexibility: flexibility to manage your cash flow, purchases and repayments. But, like all debts, you have to repay it by maintaining the payments outlined in your contract.

Let us know if you'd like another copy of your credit card contract by contacting us.

Pay more than your minimum payment

We set a credit limit based on your circumstances and ability to pay. It's used to help you avoid overspending.

It's important to make sure you manage your balance so the repayment you choose to make is within your budget.

The minimum payment amount due on your statement is just that - it's the least you must pay to keep your account in order.

You have the option of paying more than the minimum payment amount due. By paying more you'll reduce the amount of interest you accrue on the amounts owing, e.g. individual purchases and cash advances, until they are repaid in full.

Stop and call us if you get into trouble

If you find you're unable to make repayments within your budget or foresee changes in your personal circumstances that may affect your ability to make your repayments, the first thing to do is stop using your card immediately.

Then, please contact us. We may be able to restructure your payments or work out a repayment plan to help you manage and ultimately clear your debt. You might also want to consider reducing your credit limit.
