10.35amToday is Christmas Day if you're a rugby nut, and is one of the biggest days of recent Lions history. They have a chance to clinch their first tour since 1997, all they need to do is pick up one more win from their next two games.
10.37amThe Lions took a 1-0 series lead last weekend with that tense 23-21 win in Brisbane. However, they did the same against the Wallabies in 2001, and the men in gold went on to win the series. That tells you all you need to know, the job isn't done yet.
10.39amA lot has happened since the triumph in Brisbane last weekend though, and one of the biggest talking points is Warren Gatland's team selection, as he makes five changes from the opener.
10.43amPaul O'Connell's tour is over after breaking his arm, and Geoff Parling, who was withdrawn from the match against the Melbourne Rebels on Tuesday, comes into the team.
10.46amBen Youngs, Dan Lydiate, Mako Vunipola and Tommy Bowe also come into the starting lineup at the expense of Tom Croft, Alex Cuthbert, Alex Corbisiero and Mike Phillips.
10.46amSo here is Warren Gatland's team in full...
10.48amLIONS XV: Leigh Halfpenny, Tommy Bowe, Brian O'Driscoll, Jonathan Davies, George North, Jonathan Sexton, Ben Youngs; Mako Vunipola, Tom Youngs, Adam Jones, Alun Wyn Jones, Geoff Parling, Dan Lydiate, Sam Warburton, Jamie Heaslip.
10.49amAnd here are the replacements for the Lions for the match.
10.50amLIONS BENCH: Richard Hibbard, Ryan Grant, Dan Cole, Tom Croft, Sean O'Brien, Conor Murray, Owen Farrell, Alex Cuthbert.
10.55amThe Lions will face a huge physical test against the Aussies. Captain James Horwill, who was cleared after being cited for an alleged stamp on Alun-Wyn Jones, had the following to say.
10.55amHORWILL: "The mood in the camp this week has been desperate and keen. We're keen to get out there and get stuck in."
10.56amHorwill's name was met with boos by the Lions fans after being read out.
10.58amThe men in gold make two changes, with Kurtley Beale and Joe Tomane coming in at the expense of injured duo Berrick Barnes and Digby Ioane.
10.58amAdam Ashley-Cooper and Christian Lealiifano have both been passed fit for the match, while Jesse Mogg and Rob Horne earn a spot among the replacements.
10.59amAUSTRALIA XV: 15 Kurtley Beale, 14 Israel Folau, 13 Adam Ashley-Cooper, 12 Christian Lealiifano, 11 Joe Tomane, 10 James O'Connor, 9 Will Genia, 8 Wycliff Palu, 7 Michael Hooper, 6 Ben Mowen, 5 James Horwill, 4 Kane Douglas, 3 Ben Alexander, 2 Stephen Moore, 1 Benn Robinson.

11.01amOut come the Lions on to the field to a huge roar from the crowd.
1 minBeale clears the ball into touch with the boot into touch on the halfway line, and the Lions will have a lineout.

3 minThe Lions are awarded a penalty on the halfway line after Beale is penalised for not releasing the ball.
4 minHalfpenny is going for the posts, it's a heck of a long way, but if anyone can do it, it's Leigh.
5 minIt's off the bar! So close to a brilliant three points.
5 minThe Lions win the lineout, they're doing well from those so far, and start to breakaway. It goes to a scrum which the Aussies steal and race away down the right, only to be stopped before Genia is punished for not releasing the ball.
7 minAustralia have conceded another penalty after a quality drive from the Lions after a lineout. Sexton kicks into touch, and the Lions now have a lineout just yards from the tryline.
9 minThe Lions are really on the frontfoot at the moment and force Australia into conceding another penalty, this time for collapsing the maul. We're about 10 metres from the Wallabies tryline.

13 minThe Lions will have the advantage on this lineout.

15 minThe Lions are punished for collapsing the scrum! Penalty to the Wallabies!
16 minThe men in gold are going for the kick, and it's Christian Lealiifano who is on penalty duty. Big moment.
17 minPENALTY SCORED! Lions 3-3 Australia (Christian Lealiifano)
17 minNo mistake from Lealiifano, you wonder how the first Test would have finished had he not been taken off on a stretcher in the first minute. He scoops it from the right and brings Australia level.
18 minThe Lions are becoming quite sloppy. They have been very poor in the scrum so far in this match, and we're about to have another just inside the Australia half.
20 minThe Lions are given a penalty after Australia come into the ruck off their feet.
22 minPenalty to Australia, Lealiifano on the kick. Brilliant chance for the Wallabies here.

29 minFight! Ben Youngs is involved in a bit of shirt grabbing, it's quickly defused though and the Wallabies get the lineout.
31 minO'Connor fumbles the ball going into the ruck, and is hit hard by the Lions forwards. The tourists have a scrum now.
32 minThe Lions win a penalty after some brilliant driving in the ruck. It's on the Wallabies 10-metre line, and this is well within Halfpenny's range.
33 minPENALTY SCORED! Lions 9-6 Australia (Leigh Halfpenny)
33 minThe Lions are back in front and Halfpenny has done it again. It's a superb kick from the Welshman from the right that never looked in doubt of earning the points.
35 minThe Lions now have a lineout inside their own half and will keen to just get rid and get out.
36 minThe Lions give away the penalty after Ben Youngs is offside. Lealiifano will take and should make this 9-9.
37 minPENALTY SCORED! Lions 9-9 Australia (Christian Lealiifano)
38 minLealiifano is showing no signs of cracking under the pressure in Melbourne, and hits a big kick from just inside the Lions half to level the match up once again.
39 minThe Lions are big on the offensive and are desperately going the try.
39 minPenalty to the Lions about 15 metres from the tryline, it looks as if they are going to kick into touch.

46 minThis game is so finely poised at the moment.
47 minWhat a ruckus. Two turnovers in the space of 10 seconds, and the play goes from the Aussies' tryline back to the halfway when Vunipola's horrible pass gives the ball away before committing a penalty by being offside. He hasn't had a good game.
49 minThe Lions lose another scrum, and will have a real job on their hand to get this back.
50 minOr will they? The answer is no as Australia are penalised for not releasing the ball. The scrum from the Lions has been poor but they have been better at the breakdown.
51 minAustralia have a great chance to score! They have the line and the momentum, desperate defending from the Lions.
52 minNorth makes a huge saving tackle on Folau, who looked to be away there. Halfpenny boots away the advantage. The atmosphere is electric!
53 minAustralia have been given the penalty after a crazy sequence of play. Everyone can catch their breath, but Beale will kick this into touch.
54 minThe Lions drive well on their own 22 to force the Aussies out of play following the lineout.
55 minConor Murray, who has just come on, immediately wins a penalty on his own 22 after Australia fail to release the ball. Sexton boots it into touch.
