Len Neist BE, MSc, FIEAust, CPEng EngExec, MAICD

Len is an experienced and capable executive leader and senior systems engineer with experience locally and internationally for both private and public enterprises.  His career, spanning some 40 years, has prepared him to identify, understand and manage the risks associated with major change, whether it is planned or unexpected.  Len’s key skill set is in providing assurance and resilience services.  He has relevant assurance experience in enterprise risk, system safety, safety assurance, asset integrity and permissioning systems.  Len has worked as a mechanical engineer, aerospace systems engineer, regulator, policy officer, safety assurance specialist, lead incident investigator, project director, project manager, capability definition and procurement specialist, Chief Executive, Board risk specialist, executive coach and trusted advisor to government.

Len is currently Chief Engineer for Public Transport Victoria following an assignment as the Shadow Operator for the Melbourne Metro Tunnel Project.  Prior to this role he was Executive Director Health &Safety for WorkSafe Victoria, Chief Executive of the NSW Independent Transport Safety Regulator and a member of an international advisory group assisting Abu Dhabi to determine a safety and security strategy for surface transport development.  Len became involved in surface transport whilst working as a principle consultant for Booz Allen Hamilton leading their Assurance & Resilience practice in Australia.  During this time, he was selected as the risk and systems advisor to the NSW Special Commission of Inquiry into the Waterfall rail disaster.  Before joining BAH, Len was senior systems engineer for a small defence systems engineering consultancy after his Air Force career as an aerospace engineer.  His last role in the RAAF involved conceptually defining and establishing the defence Airworthiness Coordination and Policy Agency (ACPA).  During his time as director of ACPA, Len was responsible for developing the defence Airworthiness Policy.


Len has built his career around defining requirements to assure the integrity of operational systems, where integrity is focused on safety, reliability, maintainability and operational effectiveness of complex technical systems.
