Benefits of contributing
You’re probably already growing your retirement savings through the 12% compulsory Super Guarantee or SG contributions made by your employer.
But these employer contributions alone, might not be enough for you to continue doing the things you love when you're no longer working.
To afford a ‘comfortable’ lifestyle when you retire, and have access to things such as private health insurance, internet at home, going out for dinner or taking holidays, you might want to think about boosting your savings by making extra contributions to your super account, starting today.
There are benefits to making extra contributions
- It’s cost-effective to add money to your account with us, as there’s generally no cost to do so
- It’s easy - you can boost your super by making payments through BPAY, by cheque or even by money order
Please note: we are required to send you confirmation every time you make a contribution using BPAY. - If you’re a WA public sector employee, you can make extra contributions through your employer
- If you work outside of the WA public sector, you may be able to make extra contributions through your employer, depending on their arrangements
- You have the flexibility to start, stop, or change how much you want to add, whenever you like
- There could be tax benefits as super is generally taxed at 15%, when you make your contributions, which is generally less than the tax you pay on your income, or your ‘marginal tax rate’
- Your investment option could also be more tax-effective.
If you have a GESB Super account, your earnings are only taxed at 15% when compared to investments outside of super which may be taxed at up to 49%
How to make extra contributions
There are several ways you can make voluntary contributions. You can make them:
Via your employer

Make an after-tax payment of $20 or more using BPAY. All you need is your BPAY reference number and our biller code.
These details are available in Member Online.
