George North is pinged for a high tackle and Australia kick to the corner.

Wow.

That was an outstanding try, Ben Donaldson at 10 has been really quick but cause he went up so quick the inside pass caught him stuck.

Brilliant ball off the top of the lineout from Aaron Wainwright and then the ball into midfield.

The inside ball to Jac Morgan and it's a brilliant break he beats, three players and Gareth Davies does the rest.

You're right Matt.

Looking at the colours of shirts in the crowd, I'd say it was a 70/30 split in favour of Wales fans

And the first penalty goes to Wales straight from the kick off.

Dan Biggar gets the chance to pump the ball up field.

Wayne Barnes blows his whistle and Ben Donaldson gets us underway in Lyon.

What will the next 80 minutes have in store?

I think there are few more Welsh fans than Aussies judging by the anthems.

I'm confident we can grind this out, the confidence is there and I believe we are going to win.

We just need to do our job and get through to the next stage.

Australia ended a run of three successive defeats to Wales when they came from behind to win 39-34 in Cardiff last November.

It's usually a tight contest between these sides, 11 of the last 15 encounters have been decided by seven points or less.

This is the first time in four years that Wales come into the game ranked higher than Australia.

This is the eighth World Cup meeting between the teams - equalling France v New Zealand as the most played fixture in tournament history.

Overall record (45 games): Wales 13-31 Australia

World Cup record (seven games): Wales 2-5 Australia

Second row Adam Beard has honour of leading Wales out on his 50th cap and what a reception from the fans.

They all have the torches on their phones on, it's a concert atmosphere.

OK, so I mentioned earlier that we would try to make sense of the different permutations tonight.

If Wales beat Australia they are assured of a top two finish and qualify for the knockout stages.

If Wales draw with Australia then any win over Georgia will be enough to qualify.

If Australia get a bonus point win then:

• If Wales get two losing bonus points, they would need a BP win over Georgia
• If Wales gets one losing bonus point, they would need a BP win over Georgia, but it would then more than likely to come down to points difference

If Australia win without bonus points, and Wales gets a bonus, then again, a BP win over Georgia will be enough.

If Wales lose without a bonus point, then it's all up in the air and it could come down to points difference.

So, all clear now?

Yeah right.

Former Wales centre Jamie Roberts on ITV: "When the draw was made we knew this was going to be the big pool match, the amount of jeopardy on this game and those are the games you want to play in as a player.

"Former Wallaby centre Tim Horan described this as the biggest game in the professional era for Australia, this is where stars of the game are made."

Australian head coach Eddie Jones on S4C:

"This is a quarter final a couple of weeks early for us. We've had a really good preparation after looking at Fiji ready for an aggressive Wales team.

"We know how Wales want to play and we'll try and break the game up if we can.

"When you're putting pressure on the opposition, you force them into mistakes and we want to be the team forcing mistakes.

What a contrast as Australia head down the tunnel, there's a massive boo from the crowd.

Warren Gatland knows exactly how to prepare his teams for a game like this.

The self-confidence he can give to his sides, making them think they're the fittest sides.

Wales have to focus on the simple things, not over play and the half-backs are going to be crucial with our experience against Tate McDermott and Ben Donaldson who isn't used to playing at fly-half.

Blimey, I'm not sure what sort of game Australia's Will Skelton is expecting today but at yesterday's captain's run he was clearly getting his teammates ready for a slugfest!

The mind games of Warren Gatland have almost settled down, you can feel the pressure on Australia and Eddie Jones.

I don't think Wales will play too much rugby, I think they will be happy to kick the ball down the field, leave Australia run it back and say, "Let's see what you've got".

It is going to be a really interesting battle.

Bryce Roberts from Perth evidently has split loyalties tonight, as someone with a Welsh father and an Australian mother.

So who will he be supporting?

“Australia is on the heart side,” he says, pointing to his shirt.

“But I hope they both get four tries each and Wales get a [losing] bonus, so both teams go through.”
