Welcome to Mercer Business Super

New account, same great fund


Your super is on the move


As part of Mercer Super’s ongoing commitment to make your super easier to manage, your Mercer SmartSuper Plan account will move to Mercer Business Super around 20 March 2026.

We’re moving all Mercer Super plans onto one modern technology platform. This will make it easier for you – and our 1 million plus members – to find key account information and help grow your super.

 

What does this mean for you?


Your account details will change, including your plan name, Unique Superannuation Identifier (USI) and account number. It’s important that your employer updates these details from 31 March 2026.

The good news – this move won’t impact your account balance, nominated beneficiaries, or investment options. You’ll keep benefiting from our history of positive investment performance1 and have access to help and guidance at no extra cost.

 

New plan name: Mercer Business Super

New USI: 19905422981708

  • How do I let my employer know about the changes?

    If you receive employer contributions to your Mercer SmartSuper Plan account, you need to notify your employer of your new account details to ensure contributions continue without delay.

    Let us do it for you

    We sent you a notice about the move in February 2026. This notice included a link to let your employer know about the move. If you received this notice by email, it’s saved in the ‘recent communications’ section of your online account.

    Go back to that communication and follow the link, which is personal to you. That’s why we can’t provide it here.

    If you can’t find it or need help, call our Helpline on 1800 682 525 (Monday to Friday, 8am-7pm AEDT).

    Or tell your employer directly

    If you would prefer to simply pass on the information yourself, the main things your employer needs to know are:

    • New Plan name: Mercer Business Super
    • New USI: 19905422981708
    • New account number: (we’ll send this to you in early April, shortly after the transfer is complete)

    Your employer should not use these details before 31 March 2026

  • When (and how) should I cancel scheduled BPAY® payments?

    If you have automatic BPAY® payments set up, please cancel them before Monday 16 March 2026 to avoid delays. Any contribution received using your current BPAY® details after Monday 16 March 2026 will be returned. Please note, refunds can take up to six weeks to process.

    You can stop an automatic BPAY® payment at any time until the date it’s scheduled to take place. To do this:

    • Log in to your online banking
    • Choose the BPAY® or bill payment option
    • Follow the prompts to cancel the payment.


    Steps may vary depending on your bank. Contact your bank if you need help.

    After the transfer is complete, we’ll send you your new BPAY® biller code and reference number. You can also find them by logging into your account from 31 March 2026. Use these details to make future contributions and continue to grow your super.

    If you can’t find it or need help, call our Helpline on 1800 682 525 (Monday to Friday, 8am-7pm AEDT).
