Tunisia 0-1 Australia
Tunisia have attempted 17 shots at this World Cup so far, but have only hit the target with one of those.
Will they be more ruthless in the second half? Back under way.
HT: Tunisia 0-1 Australia
It's been a frustrating 45 for Tunisia. They have not tested the keeper, who has been well protected by his defenders.
HT: Tunisia 0-1 Australia
The Australia fans looked in great spirits before the game and no doubt they will have been buoyed further by their side's impressive first-half showing.

It’s Mitchell Duke's quick way of thinking - that’s why he scored that goal.
He’s on his front foot and knows he can only use the side of his head to score.

That first half was really entertaining. It was physical from the first whistle.
HT: Tunisia 0-1 Australia
A lot of that first half has been played in the Tunisia half and that is shown by the average position of each player.
Australia are the purple circles and have six players in the Tunisia half on average. They are particularly keen to get Mathew Leckie (seven) close to Mitchell Duke (15).
Their full-backs (five and 16) are also pushing forward and leaving the two centre-backs to deal with Issam Jebali (black, nine) who is the furthest forward Tunisia player.

Mark Schwarzer
Former Australia keeper on BBC One
Fantastic. Australia have done everything they said they wanted to do and took the game to Tunisia from the off.
I never said it was going to be pretty, it's a battle but the plan was to be on the front foot.

Danny Murphy
Former England midfielder on BBC One
Australia have been absolutely tremendous. The work-rate, the quality. That man Mitchell Duke has epitomised everything that has been good for them.
HT: Tunisia 0-1 Australia
That late Youssef Msakni chance represented the best chance of the first half according to Opta's Expected Goals tool.
Tunisia have actually created the best two chances (shown by the bigger black circles) and their xG score is 0.35 compared to Australia's 0.31.
They trail at the break though.

The beers will be going down well in Sydney.
Tunisia 0-1 Australia
Australia have defended well and made some important blocks when under pressure. They comfortably deal with Tunisia's latest corner.
Tunisia 0-1 Australia
Corner to Tunisia right at the end of the half.

Danny Murphy
Former England midfielder on BBC One
Graham Arnold couldn't have asked for any more of his Australia team. They've been well organised, they've been a threat. Everything he could have wanted, they've given him and now they have a lead to hang onto as well.
Tunisia 0-1 Australia
Huge chance for Tunisia but Youssef Msakni puts it wide from close range. The experienced Tunisia captain cannot believe it.
It should be 1-1.
Tunisia 0-1 Australia
The passing accuracy of the full-backs has been lacking in this game.
Tunisia left-back Ali Abdi (top image) has completed six of his first 13 passes, misplacing seven.
While Australia right-back Fran Karacic (bottom image) has only completed five of his 11.
Wayward.

Tunisia are just looking for those statistical balls going forward, particularly in the channels.
Once they do get the support up there, they have incredibly talented technicians.
Tunisia 0-1 Australia
Five minutes of added time.

One Tunisia fan wearing a very extravegant, feathered helmet-hat, has just stood up and shouted something near the media box. He looked frustrated...
