Some of America's largest fast-food chains have come under attack in a US TV ad for using frozen Australian beef in their burgers.
Ohio-based Wendy's, the third-biggest fast-food burger chain in the world, unleashed the humorous campaign across the US to promote its use of "100 per cent North American" beef patties.
Rivals including McDonald's import Australian beef to the US.
The Wendy's TV commercial, which has been receiving big air time in the US, includes three tough Aussie rugby players, with one gruffly asking: "What's wrong with Australia?"
