Hello,
Given that the owners of each Self Managed Super Fund are represented by their Trustee (e.g. Australian Executor Trustees Limited, Perpetual Superannuation Limited, etc) it is not actually possible to find the contact details of the owner directly. Although it IS possible to find the name of the owner, identifying exactly who this individual is would not be possible without trying to initiate contact through the Trustee.
If you wish, I could compile a list of SMSFs with the SMSF name/ABN, the owners' name, and the details of their Trustee.
Please let me know. Thanks.
