Director General of Victoria’s Major Transport Infrastructure Authority Corey Hannett is stepping down next month to seek new opportunities.

During his time with the MTIA Mr Hannett has overseen a massive boom in construction across the state with a $100 billion pipeline of transport projects including the Metro Tunnel, Level Crossing Removals, the West Gate Tunnel and the North East Link.

After eight years of leading the state’s Big Build, Mr Hannett, formerly Chief Executive of the Regional Rail Link Authority, says it’s time to move on and seek new career challenges.

In a statement on LinkedIn, Mr Hannett said it has been the greatest privilege of his career to lead the MTIA.

“I will miss working alongside the passionate and dedicated team at MTIA, as well as our construction partners, but the time is right for me to look for new opportunities,” he said.

“It’s been a very busy and challenging eight years in this high profile and demanding role.”

He’ll be replaced by Level Crossing Removal CEO Kevin Devlin in late March.

“Since we were elected in 2014, Corey has led the historic Big Build program of works that has transformed the state and created tens of thousands of jobs,” Premier Daniel Andrews said in a statement.

“Corey’s passion for the sustainability of the construction sector, and the safety of workers on the ground, have been hallmarks of his leadership and I thank him and wish him, and his family well for the future.”

The MTIA is one of several agencies responsible for big infrastructure initiatives in the state including including the North East Link Program ($14 billion), the Level Crossing Removal Project ($17.6 billion), the Metro Tunnel Project ($12.4 billion), the West Gate Tunnel Project ($10.2 billion)  and future major projects including the Melbourne Airport Rail ($8-13 billion), the suburban rail loop ($130-200 billion) and the Western Rail Plan ($2 billion).
