Michael Petrozzi






Michael completed his Bachelor’s degree with First Class Honours and the University Medal in geosciences at Sydney in 1994. His next step was to embark on a PhD in collaboration with Waste Service NSW and Australian Nuclear Science and Technology Organisation (ANSTO).

Throughout his PhD Michael worked independently which developed his skill set for the workplace. Michael explains, “It taught me how to work autonomously and have a mindset of focus and perseverance."

Michael’s research also provided him with invaluable industry connections. Michael credits his PhD as a way of fast tracking his business career.

Michael also identified niche areas where he could apply his knowledge and experience. This led him to his first role – setting up a multidisciplinary environmental, geotechnical and mining services consultancy company Consulting Earth Scientists. In July 2011, he sold Consulting Earth Scientists by means of a management buyout. This allowed Michael in his role as Managing Director of Macquarie Drilling, a drilling services business, to develop both organically and by adding bolt-on acquisitions to a core business which started in 1993. Macquarie Drilling is a diversified Australian drilling contractor with operations in coal, mineral exploration, mining, underground and site investigation drilling. “I believe that the key to being successful in any industry is to stay close to your core business and to remain customer focused.”

This philosophy has worked well for Michael with Macquarie Drilling ranked #46 in the 2011 BRW Business Magazine's 100 Fastest Growing Companies in Australia.
