Son Heung-min proved the hero as South Korea defeated Australia 2-1 in extra time to progress to the semi-finals of the Asian Cup.

Victory kept alive South Korea's hopes of a third Asian Cup title and a first since 1960, as they teed up a last-four tie with Jordan, who beat Tajikistan 1-0.

South Korea had to do it the hard way at Al Janoub Stadium on Friday, after Craig Goodwin volleyed Australia ahead in the first half.

Hwang Hee-chan’s stoppage-time penalty forced extra time, however, with Son's spectacular free-kick in the 104th minute securing the win, with Aiden O'Neill's VAR-awarded red card then compounding Australia's frustration.

"This isn't really the way we want to win matches but we were ready to battle hard," Son said.

"Winning this way will help with the morale of the whole team. I was really touched by the sacrifices that everyone on the team made. Each and every one of the team deserves to be complimented."

Australia goalscorer Goodwin said: "We were one minute away from going through.

"If we had taken those chances, we could have put the game to bed but Korea is a great team with great players and we gave them some opportunities from set-pieces that we didn't need to. And when they have quality like that with Son, they punished us."

South Korea's victory came after Jordan had snapped the dream run of tournament debutants Tajikistan.

Vahdat Hanonov's own goal midway through the second half proved decisive at Ahmad bin Ali Stadium.

Mousa Tamari had the chance to extend Jordan's lead but the winger shot just wide from inside the area.
