Australia ended a 16-year wait for a World Cup last-16 place as Mathew Leckie's strike earned them a gritty 1-0 upset win over Denmark in their final Group D match on Wednesday.
After a goalless first half in which Denmark looked lively and had more possession, Australia scored on the counter in the 60th minute when Leckie got past the Danish defence and twisted into space before slotting the ball home.
Australia finished second with six points, level with group winners France after the world champions lost 1-0 to Tunisia. Denmark were bottom on one point with Tunisia third on four.
They now face the winner of Group C, pre-tournament favourites Argentina, in the evening of Saturday, December 3.
"I'm proud, exhausted, everything really. It's hard to describe the emotions right now," Leckie told Australian broadcaster SBS.
"We always knew we could do it as a group. We had our doubters but our spirit, our belief, our work ethic and how close we are as a group shows on the pitch.
"The last 15, 20 minutes we battled until the end. It didn’t matter what they threw at us, we weren't conceding. We'll make the most of it tonight, but then it's all about recovery."

What is Australia's World Cup record?
Australia have competed at the Fifa World Cup on six occasions, in 1974 and from 2006 to 2022.
In all but one of their outings at the tournament, they have failed to progress beyond the group stage, with the one exception of 2006 when they placed 16th in the round of 16.
The Socceroos qualified for this year's edition via June's intercontinental play-offs, defeating Peru on penalties, meaning they only just scraped their way in.
