The Systems Engineering Society of Australia (SESA) is a technical society within Engineers Australia and is also the INCOSE chapter within Australia. Candidates for CSEP and ESEP in Australia may apply through SESA and have their applications reviewed by Certification Application Reviewers within Australia. 

Candidates who already have their Chartered Professional Engineer (CPEng) have a streamlined path to CSEP through the Chartered Australian Systems Engineering (CASE) path. These individuals have reduced application documentation and references compared to those who apply directly for CSEP.
