Australia secured their place in the FIFA World Cup Round of 32 after battling to a tense 0-0 draw against Paraguay in their final Group D fixture, surviving late pressure to keep their knockout hopes alive.

Needing only a point to progress, the Socceroos produced a disciplined defensive display in a cagey contest where clear-cut chances were at a premium.

The result saw Tony Popovic's men finish second in Group D, while Paraguay also advanced as one of the qualified teams after earning the crucial draw.

Australia enjoyed the better of the opening exchanges, with Jordy Bos and Cristian Volpato providing attacking intent down the flanks.

Bos came closest to breaking the deadlock in the first half, forcing a save from Paraguay goalkeeper Orlando Gill, but neither side could find the finishing touch.

Popovic, who made six changes following Australia's defeat to the United States, handed 18-year-old Lucas Herrington his World Cup debut.

The young defender impressed with a composed performance at the back as Australia maintained their defensive shape throughout much of the contest.

Paraguay emerged with greater urgency after the interval, led by the lively Julio Enciso, who repeatedly tested Australia's organised backline.

As the clock ticked down, the South Americans piled on the pressure, creating anxious moments inside the Australian penalty area.

However, the Socceroos' defence stood firm to record their second clean sheet of the tournament.

Despite the late Paraguay surge, Australia avoided any costly mistakes and held on for the point they needed to reach the knockout stage.

The draw marked Australia's third group-stage match after defeating Turkey and losing to the United States.

With four points from three matches, the Socceroos finished runners-up in Group D and advanced to the Round of 32, where they are set to face the second-placed team from Group G.

While the encounter lacked attacking fireworks, Australia's tactical discipline and defensive resilience proved decisive.

Having entered the match knowing a draw would be enough, the Socceroos managed the contest effectively before withstanding Paraguay's late assault to keep their World Cup campaign alive.
