John Grill

John Grill (born 1945) was the CEO of Australian-based engineering company, WorleyParsons. He graduated with Honours in Civil Engineering from the University of Sydney before joining ESSO Australia in 1968. John then moved in 1971 to be Chief Executive of Wholohan Grill and Partners, a civil engineering firm. This specialised consulting practice acquired the business of Worley Engineering Pty Limited in Australia in 1987. Following group restructuring, in 2002 Worley Group Limited listed on the Australian Stock Exchange.

In 2004, Worley Group Limited acquired Parsons E&C Corporation, a US-based global project services company, and in time amalgamated with various other parties to form what is today known as WorleyParsons. He listed WorleyParsons on the Australian Stock Exchange in November 2004 and is the company's largest shareholder. An engineer by profession, the notoriously media shy Grill is nevertheless very well respected in engineering circles. He was named Engineers Australia Professional Engineer of the Year 2006.
