The Parks Victoria board forced Bradley Fauteux's hand after he had served less than a year in the job.

The case is to be referred to the Independent Broad-based Anti-Corruption Commission.

Minister for Environment Lily D'Ambrosio said while the matter was under investigation, the behaviour had breached public service standards.

"That's a matter that's under investigation at the moment, but certainly one that has breached the various standards of the public service board, and also behaviours that are appropriate to a CEO of such an important organisation," she said.

Parks Victoria confirmed Mr Fauteux's employment had "concluded" today.

Parks Victoria chairman Andrew Fairley said the termination resulted from "unacceptable conduct" that breached Parks Victoria's values and ethics policy and the Victorian public sector code of conduct.

"We are determined that this matter will not interrupt the excellent progress that Parks Victoria has been making," Mr Fairley said.

Mr Fairley, however, praised Mr Fauteux as an "outstanding communicator" of the importance of Parks Victoria.

Mr Fauteux commenced work as chief executive in November last year, having served as managing director of Ontario Parks.

Parks Victoria's chief legal counsel Margaret Gillespie has been appointed acting chief executive.

The search to find a replacement for Mr Fauteux will begin immediately.
