Farmers have criticised Qantas for serving foreign-sourced cheese and crackers aboard its flights.
However, the Flying Kangaroo has hit right back, saying the claim is misinformed.
New South Wales (NSW) Farmers chief executive Peter Arkle said serving New Zealand-produced snacks to Qantas passengers was "hardly in the spirit of Australia."
"The cheese isn't from an Australian dairy farm, the crackers aren't made of Australian wheat, and we would really like to see them backing Australian families,"Arkle told AAP.
He said it was disappointing to see foreign produce offered when NSW growers were great supporters of the airline.
"The Qantas brand promise is so intimately tied to the Australian identity, we think it would be the right thing for Qantas to support Australian grain produce where that's possible," Arkle said.
However, the airline, which has been under fire recently from passengers enduring delays and cancelled flights, has hit back.
A Qantas spokesperson told AAP the airline was one of the biggest private-sector supporters of Australian farmers in the country, using products and services from more than 13,000 small local suppliers.
"The overwhelming majority of food and wine that we serve on board our aircraft and in our lounges comes from Australian farms and producers," the spokesperson said.
The airline said that as well as being the third-largest buyer of Australian wine, it served passengers NSW-grown beef and cheese from the Bega.
"Unfortunately, there are no Australian producers that offer a combined cheese and cracker product, which is why we source these from New Zealand," the spokesperson said.
Qantas has invited NSW Farmers to run the group through the "vast list of local farmers and producers" it supports.
However, an NSW Farmers spokesperson doubled down on the criticism.
He said a quick search of a major supermarket's online catalogue revealed at least two major food businesses that produce a cheese-and-crackers product made from almost all Australian ingredients.
"Obviously, this is a quick desktop search, not an exhaustive market study, but the clear message here is that you can find an all-Australian alternative quite easily if you are motivated to," he said.
NSW Farmers said with recent price hikes in Australian-grown produce since COVID, there had been a trend among supermarkets and other food suppliers to source their products internationally.
"We're seeing it from the big retailers as well, particularly for tinned fruit and vegetables or frozen fruit and vegetables, that there has been that tendency to source overseas produce," Mr Arkle said.
"We'd like to see Aussie retailers backing up farmers where they can."
NSW Farmers has urged consumers to check the country-of-origin labelling and support Australian-grown produce.
