Interest is paid either monthly, annually or at maturity.  Some of these rates are highly competitive, whilst those for more short term deposits aren’t such a great deal. For this reason, it’s important to compare interest rates with Savvy prior to investing. 

Platinum Plus Club Membership 

Higher interest rates (0.05% to 0.10% p.a. more than those above on average) are available for Platinum Plus Club members.  To be eligible to become a member of this club, you will need to be aged 55 years or over or to be a Trust or SMSF where the main trustee is aged over 55 years.  There are no application fees or ongoing administration fees for this club. 

Grace period 

There’s a 14-day grace period after the maturation of the term in which you can give the bank instructions about what you wish to do with your funds.  Your options are: 

  • Reinvest your funds for another specified term 
  • Reinvest for another term and increase the amount you deposit 
  • Have your funds and interest earned paid into another Great Southern bank account, which must be in the exact same name as the term deposit account 

Early withdrawal 

If you need to withdraw your funds early, an interest adjustment will be applied.  This means the amount of interest you’ll receive on your deposit will be reduced on a sliding scale according to how early you wish to withdraw your funds.  For example, if your funds have remained in place for between 40% and 60% of the original term, you’ll receive 60% of the interest which would’ve been due if you’d kept those funds in place for the full term. 

How do I open a Great Southern Bank term deposit?

You can open an account online or apply via post by downloading and printing an application form and sending it physically to the bank. You can also phone to apply or apply in person by visiting one of its branches. 

To open a term deposit, you’ll need to provide 100 points of identification.  This can be achieved by providing details of your driver’s licence and passport.

The pros and cons of Great Southern Bank term deposits


Competitive interest rates for longer terms 

Some of the interest rates on offer are highly competitive and offer great value for your nest-egg. 

Platinum Club membership boosts interest 

If you’re aged over 55, a free membership to the Platinum Club will gain you additional interest to help boost your savings. 

No setup or ongoing fees  

Great Southern Bank doesn’t charge any setup or account maintenance fees, so there aren’t any hidden charges to eat away at your savings.


Lower rates for certain shorter terms 

While some of the interest rates offered by Great Southern Bank are on a par with, or higher than, those offered by competitors, shorter term deposit rates aren’t as competitive. 

Minimum account balance of $5,000 

Unlike other smaller banks which have a minimum deposit amount of $1,000, you’ll need to have saved $5,000 to get a term deposit with Great Southern Bank. 

Balance can’t be paid to another bank 

You’ll need to have a bank account or savings account with Great Southern Bank in order to pay in and receive your term deposit funds at maturation. 

More of your frequently asked questions about term deposits

How does a term deposit work?

A term deposit works by providing a fixed rate of interest for a lump sum that is deposited with a bank or financial institution for a set amount of time. Term deposits are offered for a period of a few weeks up to five years, in which time your savings are locked away so they can’t be touched (except in an emergency or in case of severe financial hardship). The interest earned on your savings can either be paid regularly (so the interest compounds) or at the end of the term as a lump sum. If you opt to receive your interest as a lump sum, you’ll generally be offered a higher rate. 

What are the advantages of a term deposit?

The advantages of a term deposit are that you’ll have certainty. You’ll be certain exactly how much interest your savings will earn over a pre-defined period, as the interest rate paid on a term deposit is fixed for the duration of the term. As your savings are locked away for that term, the temptation to dip into your savings is taken away. You can be certain that your savings will be intact at the end of your term, and know exactly how much interest they have earned. 

How do I find the best short term deposit rates?

The best short term deposit rates for term deposits in Australia are typically offered by online financial institutions, smaller mutual banks and credit unions. This is because mutual banks and credit unions channel all profits back to their members, which means they’re able to offer more attractive interest rates. Online banks also don’t have the overheads of maintaining bricks and mortar branches, so they’re often able to offer very attractive interest rates for short-term savings too. For this reason, it’s important to compare interest rates with Savvy before making your financial investment decision. 

How can I work out how much interest I’ll earn on my term deposit?

You can use Savvy’s term deposit calculator to help you work out exactly how much interest your savings will earn over a set period. Just enter in the amount you wish to deposit, the term of the deposit and the interest rate offered, and the calculator will show you how much interest your savings will earn.
