The first national brand identifying all Australian agricultural produce sold overseas with a ­distinctive new “True Aussie” logo will be unveiled today to help bolster global sales of ­crucial exports.

The True Aussie brand, which can be used on all fresh or unprocessed food that is 100 per cent sourced from Australian farms, aims to increase sales of key exports such as milk, beef, lamb, seafood, cheese, sugar, fruit, nuts and grains through easily recognised country-of-origin labelling.
