Mathew Leckie’s second half strike helped Australia to a 1-0 win over Denmark, and a place in the Round of 16 for the second time ever.
The Socceroos made one change from the side who narrowly beat Tunisia on Saturday, as Milos Degenek came in at right back for Fran Karacic.
Denmark manager Hjulmand made 3 changes to his team that fell to a 2-1 defeat to France at the weekend, with Jensen, Olsen and Braithwaite coming in for Nelsson, Damsgaard and Cornelius.
The first half was very uneventful, with the only real test to either goalkeeper came after 10 minutes, when Mat Ryan tipped Mathias Jensen’s powerful effort over the bar.
The second half was more of the same, with very few chances, but on the hour mark, Riley Mcgree found Mathew Leckie on the counter attack, who beat his man and fired a shot low past Schmeichel and into the Denmark goal to give the Socceroos the lead.
Denmark continued their struggles in front of goal at this year's World Cup, as they were unable to find a leveller in the final 30 minutes, meaning that Australia took the 3 points and finished in second place in Group D.
Graham Arnold’s side have reached the knockout rounds of the World Cup for the first time since 2006, and will face the winner of Group C on Saturday at 7pm.
