"With the combination of our off market bid for Ridley Corporation, our recent five year rail deal with Pacific National and the removal of the bulk wheat export monopoly, GrainCorp is entering a new phase in its development," Mr Irwin said.

"The key to the new GrainCorp strategy is value creation.

"We want to leverage the expertise and existing resources within the company to create a better performing organisation, increase the return on our assets, and improve our focus on grower and customer service and shareholder returns."

Mr Irwin said the rationale for the restructure was simple.

"There are a range of opportunities opening up in the Australian agribusiness sector and it’s our vision to become a leading player," he said.

"To achieve our vision, we need to reposition and realign the company."

Mr Irwin said the new business unit structure included: storage and handling, headed by Kevin Lloyd; ports and new business, headed by Nigel Hart; and marketing, headed by Sam Tainsh.
