The voice of

South Australian Growers


GPSA advocates on behalf of SA grain producers, representing their interests to decision-makers in all levels of government, the SA Parliament, and to commercial and other groups across the value chain.


GPSA engages industry stakeholders regarding policies we believe will promote the economic and environmental sustainability of grain production, providing leadership and influencing outcomes.

Industry Development

GPSA informs grain producers on matters of importance to their business and champions the contribution we make to the South Australian community by engaging positively with the public.



A forum focused on planning for best practice agrichemical spray application in the South Australian grain industry is being held at Freeling in March.

The forum is free for Grain Producers SA (GPSA) members and will feature a range of experts in the field of spray application, including internationally renowned expert in spray drift management Dr Andrew Hewitt and weeds expert, Professor Chris Preston.

The one-day forum will be held at the F.A.R.M Centre at Freeling on 7 March, 2024 with GPSA members able to access free tickets and non-GPSA members’ tickets being $50. Click to register your spot.


Join GPSA for an exclusive webinar addressing the imminent 3G shutdown in South Australia and its specific impact on grain producers. This critical discussion will feature insights from Telcom companies, the Regional Tech Hub, and Grain Producers SA. Engage in a discussion and learn more about the impact on businesses and community, especially in regional areas, and how the agricultural sector is adapting to the changing technology landscape.


GPSA has launched a new spray campaign titled ‘Don’t Spray Your Dollars Away’ focusing on the economic losses for grain producers who don’t do the right thing. The campaign will be featured heavily through text reminders to South Australian grain producers, in newspapers, on the radio and on social media throughout late January and February 2024.

This campaign will run side by side with our ‘Keep Your Droplets to Yourself’ Campaign – delivering many relevant facts and actions to help prevent spray drift. Download the factsheet with tips on best practice spray application here. 


Grain Producers SA (GPSA) and CropLife Australia have teamed up to launch a new initiative for grain producers in South Australia to take the ‘Responsible Spray Applicator Pledge’.

South Australian grain producers are being encouraged to take the voluntary pledge to demonstrate they are using best practice when spraying agrichemicals on-farm by visiting

Once the grain producer has completed the pledge, they will be sent a ‘Spray Pledge Pack’ which includes a letter, certificate, corflute and bumper sticker, as well a $100 voucher.

About Us

Grain Producers SA is the peak industry body representing the 4,500 grain farming businesses in South Australia. Established in March 2012, GPSA was formed out of the need for an organised and well-funded lobby group to be a voice for South Australian grain growers beyond the farm gate.
