In 2018, Aude began representing Argentina at U17 level. After featuring in a friendly against the United States, Aude made six appearances at the 2019 South American U-17 Championship as they won the trophy. He wasn't selected for the subsequent FIFA U-17 World Cup, due to the fact he was recovering from surgery after being diagnosed with knee tendonitis. In 2019, as well as one for the U16s, Aude received a call-up from the U17s for the 2019 Granatkin Memorial; which they won.
