About me

I was born and raised in South Africa where I qualified as a Chartered Accountant after completing my articles with Deloitte in 2015. I joined the family farming business soon after and was deeply involved in the processing side of the company during a phase of rapid expansion.  The opportunity to work in Australia presented itself late in 2019, and I moved over with my wife, Marcella, in April 2019.

When I am not at work

When I am not at work I enjoy spending downtime with my wife exploring what our new home has to offer.  You’ll find us trying out Brisbane’s favourite spots or heading out of the city to spend time with family and friends.  We love to travel, so we’re always up for the next adventure!

Why I work at Marquis

The macadamia industry is experiencing such exciting changes so there are enormous opportunities for both business and personal growth.  The company is uniquely placed to work with all levels of the value chain from the growers, to the processors, marketers and customers, so the company is more than a business, it’s personal!  Marquis has such an incredible team of dedicated staff so it’s a pleasure to head into the office every day.
