Blake AgmarkBlake Mallon

Blake has a Bachelor of Agricultural and Resource Economics (Honours) from the University of New England and a Diploma of Grain Management through Grain Trade Australia.

Blakes interest in grain spawned from his upbringing on a broad acre grain producing farm at Quambone, NSW (200km North West of Dubbo). He left high school and then travelled through
Europe after which he spent some time on the family farm.

Blake’s first taste of grain marketing was casual harvest work with a grain broker in Dubbo as work experience for his bachelor degree. Blake joined the Agmark team early 2016 in logistics and administration before transitioning into a trading role.

Blake currently lives in Narromine with his wife Sarah and son Tom and works from Agmark’s Narromine, NSW, office. In his free time you will likely find him golfing, playing rugby or water skiing.
