Arlington: Hossam Abdelmaguid scored the decisive penalty in the shootout as Egypt won their first World Cup knockout match by beating Australia 4-2 on penalties after a 1-1 draw on Friday.
Australia goalkeeper Mathew Ryan did not save any of Egypt's four penalties after replacing starter Patrick Beach late in extra time.
The victory came in Egypt's fourth World Cup appearance. Australia are now 0-3 in World Cup knockout matches.
Egypt will next face defending champions Argentina in the Round of 16 on Tuesday in Atlanta.
Harry Souttar opened the shootout by firing over the bar for Australia, and 18-year-old Lucas Herrington hit the crossbar with the fourth attempt, setting up Abdelmaguid's winning penalty.
Egypt's other successful penalty takers were Mahmoud Saber, Ramy Rabia and Mohamed Salah, the former Liverpool star who started despite a hamstring injury sustained in the team's group-stage finale.
Jackson Irvine and Awer Mabil converted their penalties for Australia.
Emam Ashour gave Egypt the lead in regulation by scoring in the 13th minute with a header that beat Beach just inside the near post. Australia levelled the match in the 55th minute when Egypt defender Mohamed Hany became the first player to score two own goals in the same World Cup.
The own goal came when Aiden O'Neill delivered a free kick from the left side of the penalty area and Hany headed the ball past goalkeeper Mostafa Shoubir, earning an unwanted place in World Cup history. His first own goal came in a 1-1 draw against Belgium in the group stage.
Less than 10 minutes earlier, Hany went down near the same spot after colliding with Connor Metcalfe during the Australia midfielder's header attempt. Medical personnel attended to Hany while a stretcher waited nearby, but he was helped to his feet and remained on the pitch after what appeared to be a concussion assessment.
Australia's only goals in World Cup knockout matches have come through opposition own goals. The Socceroos lost 1-0 to Italy in 2006 and were beaten 2-1 by Argentina four years ago in Qatar, with their goal in that match also coming via an own goal.
Omar Marmoush had a great chance to give Egypt a two-goal lead in the opening seconds of the second half, but he sent his shot wide.
The late goalkeeping switch to the 34-year-old Ryan, making his 105th international appearance, came despite several strong saves from the 22-year-old Beach, who was playing only his sixth match for the Socceroos.
Beach made a sprawling save from Rabia's header in the closing moments of regulation and, seconds later, comfortably gathered Salah's shot.
Egypt had one more chance before the end of regulation, but Haissem Hassan's effort was blocked by Souttar, who deflected the shot with his knee.
