"You see Park Ji-Sung take a tackle and get straight back up," said the Socceroos midfielder. "He's shown he plays the game in the right manner and he plays in the Premiership and understands football.
"He epitomised South Korea's performance and if you can take a leaf out of his book and do the same thing, it would've been a lot smoother game. But credit to Korea, they're a good football team."
Koo Ja-Cheol opened the scoring for the South Koreans on 24 minutes before Mile Jedinak's second-half header ensured the spoils were shared. Both teams had chances to win the game and Cahill was among those who should have made more of the opportunities that came their way.
"It's disappointing but also one of those things where if we finished our chances like myself or Harry Kewell or whoever, we would have won the game," he said.
"We showed good character to come back in the second half. It was a weird game and it was surprising to see some of their tactics. To be honest with you, they can have all the big centre backs they want, but we had so many chances. We weren't stopped, we missed the chances."
Australia next play Bahrain in their last group match on Tuesday and need a point to go through to the quarter-finals.
