Hi charliechau,
Thanks for posting in the Community!
If you haven't been able to find the super fund you're looking for first double-check the information with your employee (to rule out obvious things like typos or transposed figures) then try searching for the fund here http://superfundlookup.gov.au/. Also, you may try to check with your employee if the super fund is regulated or self-managed.
For more detailed information, you can check on this article: How to set up an Employee in QuickBooks Payroll powered by KeyPay.
