Australia, Iraq, Korea Republic and Uzbekistan will represent Asia at the FIFA U-20 World Cup Turkey 2013 after reaching the semi-finals of the AFC U-19 Championship.

Uzbekistan were the first team to reach the final four, seeing off Syria on penalties following a 2-2 draw, and were quickly joined by the South Koreans, who thrashed Iran 4-1.

A hat-trick by Corey Gameiro helped Australia ensure their presence in the semi-finals with a 3-0 triumph against Jordan, and Iraq completed the line-up by overcoming Japan 2-1.

All four sides will now take part in the FIFA U-20 World Cup in Turkey next year, although glory at the AFC U-19 Championship is still to be decided.

Uzbekistan will take on Korea Republic while Australia meet Iraq in the semi-finals on Wednesday, while the champions will be crowned when the final is held on Saturday.
