Mark O'Brien has now left State Super to take up his new role as general manager of investments at NSW Treasury Corporation (TCorp). O'Brien's move forms part of the re-structure of TCorp's investment team following the amalgamation of the three New South Wales State funds: The Safety, Return to Work and Support Division (SRWSD), SAS Trustee Corporation (STC) and NSW Treasury Corporation (TCorp). TCorp now has over $70 billion under management.
