About NetActuary

NetActuary has a focus on both traditional actuarial consulting tasks and supplying technical/computational support to advisers, accountants and lawyers. We are totally independent of any financial organisation and we work exclusively on a fee for service basis.

To ensure that there is no potential conflict of interest we don't accept financial planning requests directly from a member of the public, but through an AFSL licensed adviser.

As can be seen from the level of academic qualifications of our consultants, we believe passionately in the value of research, innovation and the use of technology to facilitate optimum solutions and services.
