Understanding Your Transfer Limits
When you need to make a significant purchase, such as a vehicle deposit or a major home repair, the standard banking transfer limits can sometimes block your transaction. National Australia Bank (NAB) applies default daily transfer thresholds to protect your funds from unauthorized access. If your planned payment exceeds these default caps, you will typically need to increase your limit before the transaction can be processed.
In most cases, your default daily limit is set to $5,000 if you have SMS security activated, or $2,500 if you do not. You have the flexibility to temporarily increase this cap up to $100,000 per day for domestic payments. Adjusting this threshold requires specific authentication steps through the internet banking portal, as the bank restricts major security changes directly within the native mobile app.

Troubleshooting Limit Changes
If you encounter roadblocks while attempting to raise your transfer cap, here is how to address the common issues.
MFA / Login Issues
- Cause: You cannot authorize the limit increase because the SMS security code is delayed or not arriving to your mobile device.
- Simple Fix: Toggle your phone into airplane mode for ten seconds to reset the network connection, then request a new code.
- Fallback Action: Call the NAB personal support line on 13 22 65 to verify your identity and have a representative apply the change manually.
Browser or App Errors
- Cause: You are trying to increase the limit directly inside the NAB mobile app, but the interface redirects you or blocks the action.
- Simple Fix: Close the app and open your device's web browser (like Safari or Chrome) to log into the full Internet Banking site instead.
- Fallback Action: Move to a desktop computer to complete the limit change if the mobile browser version is not displaying the settings menu correctly.
Locked Account / ID / Access Issues
- Cause: Entering an incorrect SMS code or password multiple times will lock your digital profile to protect against unauthorized access.
- Simple Fix: Wait for the temporary security hold to expire, or use the 'Forgot password' flow to safely recover your login credentials.
- Fallback Action: Visit your nearest NAB branch with physical photo identification so a teller can manually unlock your profile and adjust your transfer limit.
Pro-Tip: To minimize your exposure to financial fraud, make it a habit to lower your daily transfer limit back to the default $5,000 as soon as your large transaction is complete. Keeping your limit artificially high when you do not need it leaves your account vulnerable if your digital banking details are ever compromised.
Frequently Asked Questions
Q: Why can't I increase my daily limit above $2,500?
If you are trying to pay a contractor and notice your limit is capped at $2,500, this is usually because your profile is not registered for SMS security. The banking infrastructure uses SMS codes as a secondary layer of authentication for high-value transactions to ensure the genuine account holder is authorizing the movement of funds. One limitation is that you cannot bypass this requirement for domestic 'Pay Anyone' transfers online. Your practical next step is to register your mobile number for SMS security within the Internet Banking settings, which will then allow you to increase the cap up to $100,000.
Q: Why am I unable to change my limit inside the NAB mobile app?
You might be standing at a car dealership trying to increase your limit on your phone, only to find the app restricts the action. To protect users from situations where a stolen, unlocked phone is used to drain an account, the bank restricts limit modifications to the web-based Internet Banking platform. This separation creates an intentional point of friction against mobile fraud. One exception is that the app will allow you to view your current limits or completely restrict payments, but not raise them. Your practical next step is to open your phone's web browser, navigate to nab.com.au, and log in there to process the increase.
Q: Does the daily limit apply when transferring money between my own accounts?
If you need to move a large sum from your savings to your transaction account to cover a bill, you generally do not need to worry about the daily transfer limit. The bank treats transfers between your own linked NAB accounts differently than external payments, meaning these internal transfers typically have no cap, provided you have sufficient funds. One limitation is that this exemption does not apply to international transfers or accounts held at different banks. Your practical next step is to simply proceed with the internal transfer via the app without adjusting your security limits.
