Enjoy lower rates while lowering the emissions of your home
What is a green loan?
A green loan is a personal loan that’s used to buy products that reduce your home’s emissions. What does “green” mean to Great Southern Bank?
When tackling climate change, we believe individual efforts should be rewarded.
Our green loans offer personalised rates lower than our standard unsecured personal loans, making it easier and more affordable to make your home improvements. Plus, you’ll get all the clever features our personal loans have to offer, such as $0 monthly fees, unlimited extra repayments and a free redraw facility to help you save some money while you reduce the emissions from your home.
What can I use a green loan for?
If you're considering solar panels or battery packs for your home, a green loan could help make these items more financially friendly on your pocket.
Eligible green purchases**
Must be a 3-kilowatt (kW) system or above and purchased from a New Energy Tech approved seller
Must be a 5-kilowatt (kW) system or above and purchased from a New Energy Tech approved seller
Must be eligible for Small-scale Technology Certificates
Keep in mind your green purchase must be installed by an accredited installer. This helps ensure your home improvements meet all relevant Australian standards.
Estimate your personalised rate* and repayments
repayments
Your estimate repayments are calculated based on the loan type, loan amount, loan term and your credit score entered. The calculations do not include upfront or continuing credit fees and charges. Lending is to approved applicants only. All lending is subject to a detailed credit assessment, the results from this calculator do not constitute a loan application or variation to an existing facility, loan offer or loan approval.
Your contracted personal loan repayments will be set to a monthly frequency, meaning you will need to meet the agreed repayment amount by the due date stated on your loan contract each month. To meet this minimum monthly amount, you can however make repayments weekly or fortnightly.
This calculator provides general information only and should not be relied on to make a decision about a financial product. You should consider obtaining advice from an appropriately licensed financial services professional before making any financial decisions.
A secured loan is 'secured' against the asset you are borrowing for, such as a car. If you are unable to repay the loan, the lender can sell the asset to cover the costs of the loan.
An unsecured personal loan is a loan that does not require an asset as security. Your income and ability to repay the loan is still assessed, however you don't need an asset to secure the loan.
Your credit score is a number used by lenders to assess how likely you are to repay a loan. Your score is based on the information in your credit report, including:
- How you've managed previous loan and credit card repayments.
- How many loan applications you've made in the past.
- The age of your credit file.

Unsecured Green Loans explained
Have a question? Find the answers explained in easy-to-understand terms here.
In line with Great Southern Bank’s 2022-24 Climate Action Plan, and our goal of achieving net zero emissions by 2040, we have developed a range of green loan products to support our customers who share our values and want to contribute to a better future, while continuing to meet their financial needs.
To be considered green, products financed through our green loans must be:
- Hybrid and electric vehicles (via a car dealer and private seller)
- Home charging stations (for electric and hybrid motor vehicle charging) - only when purchasing a hybrid or electric vehicle
- Solar panels
- Battery packs
- Hot water heat pump
- Solar hot water system
As part of the application process, you will be asked to provide reasonable evidence (including a tax invoice) to show that the loan will be used to buy an eligible product. The documentation can vary depending on what you are buying and installing; however, we’ll help you with this step and supply the relevant information during the approval process.
The New Energy Tech website has a list of approved sellers for solar panels and home batteries .
You can check installer accreditation status at the Solar Accreditation Australia website.
A personalised interest rate is determined in large part by your credit score. This is based on a range of factors including your history of repaying loans, credit cards, and other bills. In short, the better your credit score, the lower the interest rate you’re likely to be offered.
Speaking of which, it's worth noting that while submitting a full application will likely result in a small, temporary dip to your credit score, simply getting your estimated personalised rate will not impact it.
The rate you are offered is calculated on your personal circumstances and credit history. A few different factors are considered, including:
- your credit score
- information provided in your application
- existing loans
- the loan amount and your perceived ability to repay the loan.
Don't forget the starting rate for our Unsecured Green Personal Loan is lower than our traditional Unsecured Personal Loan, so if you have a good credit history you could be rewarded with a low competitive rate.
