Grain Producers Australia (GPA) represents Australia's broadacre, grain, pulse and oilseed producers at the national level. Broadly stated, GPA was created to foster a strong, innovative, profitable, globally competitive and environmentally sustainable grains industry in Australia.

The objectives of GPA are to establish a strong independent national advocate for grain producers based on a rigorous and transparent policy development process; engage all sectors of the Australian grains industry to ensure operation of the most efficient and profitable grain supply chain; and facilitate a strategic approach to Research, Development and Extension (RDE) intended to deliver sound commercial outcomes from industry research.

GPA is the outcome of two grains industry roundtables run by Grains Council of Australia (GCA) in October 2009 and February 2010.  GCA was the former recognised peak national grain producer representative body and initiated the roundtables because it had been crippled by a fractured membership and severely limited in its financial capacity for several years.  The GCA membership and funding model relied heavily on state farming organisations (SFOs).

GPA is a not for profit company limited by guarantee and is accountable to its members through board elections and annual review of operations.  The GPA Board is directly accountable to grain producers in the same way a corporate board is accountable to its shareholders.  The charter of the GPA Board is to provide representation for Australia's grain producers and to foster a culture of service within GPA.

GPA has voluntary membership drawn directly from the community of grain producers. The members pay an application fee and an annual subscription fee which are intended to be the main source of funds for GPA.  This funding model provides an equitable system where all producers can contribute to the advocacy at a national level and alleviate the financial burden on the state-based groups to fund the national structures.
