QUEENSLANDERS will celebrate the role of farmers in sustainability feeding next Wednesday for National AgDay.

CEO Michael Guerin said the day would be a chance for Australians to recognise the good work of farmers, as well as provide an opportunity for farmers to thank fellow Australians for their continued support.

The theme for this year is #GrowForGood.

"Whether it's helping feed a hungry world, caring for our environment, or creating jobs in regional communities, every day our farmers grow for good,” Mr Guerin said.

He said agriculture was one of the fastest growing industries in the country.

"Queensland is the most valuable agriculture state, producing almost a quarter of our nation's food and fibre, so we have a lot to be proud about.”

More than 330,000 Queenslanders are employed across the food supply chain, meaning almost one in seven people are partially or entirely supported by the food sector.

The country will be brought to the city for National AgDay on Wednesday, with AgForce partnering with Jan Powers Farmers Markets in the Brisbane CBD.

"Brisbane market-goers will be able to ask a farmer about what they do and why... we will also have information flyers and giveaways to help share the message about the importance of agriculture in every aspect of our lives.”

AgDay events will be held throughout the country, and the National Farmers' Federation is running a photo competition, encouraging the country to dress in green next Wednesday to celebrate and thank the work of farmers.
