Brad Knight

Managing Director

Bendigo Office

Contact: 0429 802 538

Brad completed Bachelor degrees in both Commerce and Agriculture at the University of Melbourne with a focus on economics and finance.  Employment commenced with AWB Ltd in the 2004/5 season and over 4 years he had various roles with AWB in customer service, risk management and as a regional grain marketer based in Horsham. 

With wheat deregulation came the growth in the independent fee-for-service grain brokering industry and 5 years with grain broker Agfarm enabled Brad to continue to develop skills in individual client management, grain brokerage and execution.

As grower supply chains have continued to develop so has the demand for full end to end grain marketing services. GeoCommodities was formed in in 2013 to enable Brad to continue to focus in this area and guide clients through the ever evolving market environment.
