General Banking

  • Misplaced your card?

    Introducing Big Sky’s new block card feature

    If you’ve lost your card, you can block it temporarily via the app while you look for it. When you find it, you can unblock it just as easily.

    To use this feature log into your Big Sky internet banking app, select the card you want to temporarily block by scrolling and tapping the desired card, then use the toggle to block (red) or unblock (green).

    Note: Direct debit, recurring and scheduled payments associated with account linked to a card will still be processed successfully if a temporary block is placed on the card. All other transactions will be declined. The temporary block will remain until modified by the user via the app or by a customer service operator.

  • Electronic Banking Security

    Electronic Banking

    Customers are encouraged to be aware of any fraudulent activities targeting financial institutions. This activity can often take the form of bogus emails and telephone calls, purporting to come from your financial institution, and asking for personal account details. These are communications designed to enable fraudulent activity on your bank accounts and as such you should not provide any personal account details. Big Sky will never ask you to provide sensitive information such as passwords or log ins. 

  • Passcode Security

    Passcode security

    Pass code means a password or code that you must keep secret, as it is usually required to perform a transaction. A pass code may consist of numbers, letters, a combination of both, or a phrase.

  • Telecode


    Telecode is an additional way of indentifying you so that you can perform certain banking functions over the phone. Through the establishment of a verbal password, customers can be verified and able to speak with one of our Customer Services Consultants during business hours.

    To request a Telecode authorisation, call Big Sky on 1300 654 321 or download the Telecode Application form, complete and return to us.

    Without a Telecode your access may be restricted to making general enquiries to protect your privacy. 

    Your Telecode will be separate from any other "Access Code" or "Passwords". Please note that your Telecode is similar to a PIN and as such, should not be disclosed to anyone. Avoid nominating obvious words or number sequences e.g. Names, Birthdays, Postcodes.


    SMS One Time Password (OTP)

    Big Sky uses SMS OTP as an extra validation point for functions within internet banking. An SMS OTP is a randomly generated 6 digit code, valid for one session or transaction and delivered via text message to a registered Australian mobile phone number.

    Big Sky recommends customers register and use SMS OTP as an additional layer of security for internet banking payments. 

    A standard daily account limit of $1,250 applies. Up to this limit, SMS One Time Password (OTP) is optional. However if you require a non-standard daily account limit above $1,250 you will be required to register for SMS OTP – click the link below to find out how to register. Once registered for SMS OTP, you can add new payees to your list of saved ‘Personal Payees’, removing the need for using SMS OTP next time you want to make a payment.

Card Security

  • Keeping cards secure

    Tips to keep your cards secure

    • Monitor your quarterly statements, especially after an overseas trip.
    • Check all transactions, even the small ones, because criminals try "testing out" stolen accounts by buying inexpensive items rather than large ones.
    • Protect your cards as if they were cash - always keep them in a secure place.
    • Report lost and stolen cards immediately and arrange for a replacement card to be issued to you.
    • Do business with reputable merchants or vendors only.
    • Notify Big Sky on 1300 654 321 if you detect anything unusual.
    • Ignore unsolicited emails or phone calls seeking your personal or account information. We will only contact you to confirm details we currently have.
    • Memorise your PIN (Personal Identification Number) - never write it down, and never leave a written copy with the card or in an easily identifiable location.
  • Verified By Visa

    Verified By Visa

    Verified by Visa is a service designed to ensure you are protected whilst shopping online with your Big Sky Visa Card (debit as well as credit cards). All Big Sky Visa cards (new and existing) are automatically registered for Verified by Visa.

    As you make purchases online, Big Sky  assesses the risk of the transaction based on a number of factors. In some instances, you may be asked to confirm some personal details, for example date of birth or address, so Big Sky can be sure the card isn't being used without your permission.

    Verified by Visa can be used in most browsers however if you are using Microsoft Internet Explorer you will need version 5.5 and above or Netscape Navigator 7.1 and above.

    Each time you make an online purchase, Big Sky assesses the risk level of the transaction to identify if certain activity may seem out of the ordinary, maybe because it is a high dollar value, or a retailer you have never purchased from before.

    If Big Sky is concerned a transaction may be fraudulent, we will prompt you to confirm your identity, and you will be requested to enter some personal details unique to your account with us. If the transaction is considered high risk, you may be requested to confirm several details before the transaction is approved.

    This additional security benefit is provided to you free of charge.

  • Vigil


    With fraud on the rise, Big Sky is always looking at new ways to counter issues and threats to our Customers Visa cards. We have implemented a service that provides 24 hour monitoring of  cards 24 hours a day, 7 days a week, 365 days a year. This new service is known as ‘Vigil’ and is provided by our industry partners CUSCAL, within a new division created called the ‘Fraud Bureau Service’. Customers can now be even more confident in the fraud prevention services Big Sky provides.

    What does this mean for customers?

    If there is suspicious activity on your VISA card you may receive a call from the Fraud Bureau Service (Vigil) on weekdays, weekends or even public holidays, to discuss any transactions or attempted transactions that could be fraudulent. You will be asked by Vigil to identify yourself as the account holder with some simple identity questions, then some questions regarding the suspicious transactions that may be occurring. Big Sky will then take action to stop any fraudulent transactions.

    The Vigil Team will provide a valuable resource in spearheading Big Sky’s defence against fraud. If you have any questions about this service, please contact us.

    When you are heading overseas, contact us to let us know. This will prevent VISA cancelling any payments they think might be 'suspicious'.
