G+T has confirmed that Mr Boot is no longer at the firm; however, it is unclear whether he has started in another role at this stage.

“Michael moved on to explore new opportunities internationally and is currently undertaking consulting engagements,” the firm said in a statement.

Mr Nickless was a partner at global management consulting firm McKinsey & Company for five years. He has also held executive roles at National Australia Bank, Aristocrat Leisure Limited and, more recently, real estate investment trust GPT Group.

G+T managing partner Danny Gilbert said Mr Nickless brings significant commercial and operational experience to the role.
