The tournament has been tremendous so far, but the sense of anticipation, talking to the fans – all eyes are on these four games. Can we honestly say we know who’s going through? You can argue a case for all of them. It’s maybe the most competitive set of quarter finals we’ve ever seen.

Jerome Garces, the Frenchman who likes to play it fast, loose and laissez-faire at the breakdown, is on the whisle.

He toots the horn and we are off and running with Reece Hodge's kick claimed by Elliot Daly....

Quick anthem check.

England first up, Billy and Mako Vunipola locked shoulder to shoulder giving it big beans, while replacement Luke Cowan-Dickie bounces on his toes like a prizefighter.

Time for Advance Australia Fair, brassy and loud.

Matt To'omua, perhaps thinking about the barbs from three years in the Tigers dressing room, is hollering. Jordan Petaia, just 19, looks a little more circumspect.

• England and Australia have met 50 times. England have won 24 of those matches with Australia winning 25, a drawn game in 1997 completes the head-to-head record
• England and Australia have played each other six times in the World Cup, both sides winning three including a triumph each in the final: Australia beat England in 1991 at Twickenham and England exacted revenge in Sydney in 2003
• England have won their last six Tests against Australia, their longest winning run against their rivals. However, their last defeat against them came at the 2015 World Cup.

Jonny May looks like so pale he is almost translucent as he emerges first from the England dressing room to lead the team out on the occasion of his 50th cap.

It is one of those contests that needs you to schedule an extra trip to the cubicle before kick-off.

Here come the drums.

And the teams emerge into foaming brew of white, green and gold in Oita Stadium...

It was absolutely pouring it down as England and Australia fans piled into Oita yesterday.

Today, the sun is shining but it's still quite sweaty under the roof.

That's rugby correspondent Chris Jones waving, by the way, from his commentary position.

• England lock Maro Itoje won seven turnovers in the pool stage, the most of any player in the competition, despite playing just two games
• Wing Jonny May will win his 50th cap for England - he is sixth on England's try-scoring list with 25 tries, but only two of those have come in World Cup matches (v Wales in 2015 and v Argentina in 2019)
• Replacement hooker Luke Cowan-Dickie has scored a try in each of his three World Cup games, only Will Greenwood has scored in more consecutive games at the tournament for England (four in 2003)
• Australia's Samu Kerevi beat 20 defenders across three appearances in the pool stage, the most of any centre in the competition and more than England's top two centres combined (Manu Tuilagi nine, Jonathan Joseph eight).

There is nothing that quite matches the quarter-final weekend of a Rugby World Cup - four huge matches, tripping over each others' coat-tails, all those hopes and dreams and doubts of the past four years coming down to 80 minutes of tension and torment. Everyone in the stadium giddy with anticipation, everyone back home feeling rather sick, in the best possible way.

This is just the latest in a long line of crossed paths between Eddie Jones and Michael Cheika.

The England and Australia coach's pasts are intertwined like a helix-twist of DNA.

Both sons of immigrants to Australia, brought up in tough bits of Sydney and then team-mates at club side Randwick.

Stirling Mortlock, who has played under both, told BBC Sport about their respective characters.

"Incredibly combative, almost a thug on the pitch".

"He's got an absolute gentle heart when it comes to rugby. He's a pig in mud if he's doing a coaching clinic with other coaches or a load of six-year-old kids."

Guess which is which...

Eddie Jones was the first man out on the pitch before warm-ups. He stood in the middle of the pitch for a good while, contemplating. There's quite a lot riding on this game for the England boss.

If there is that moment today when Australia challenge England, and the score is tight, have they got that capability to make that decision when they are under pressure? The rules slightly change in knock-out rugby.

It's already a high-calibre contest in the fancy dress stakes...

There's plenty keeping fans entertained around the stadium too.

You can pose with two yellow animals (maybe birds? I couldn't work out what was going on).

Pooper v the Kamikaze Kids. Not the battle of the bands at your local indie disco, but the flanker tag-teams involved in the battle of the breakdown in Oita.

David Pocock and Michael Hooper, 31 and 27, have a combined total of 180 caps.

Their England counterparts Tom Curry and Sam Underhill, 21 and 23 respectively, have just 28.

Pocock - a three-time World Player of the Year nominee - had the South Africans squealing like a sanctuary-full of cats as he dominated their quarter-final in 2011.

Can Curry and Underhill be faster, stronger and cannier than their celebrated opponents? It could be crucial to England's hopes of a semi-final spot.

Of all the host cities we've been to so far, Oita definitely seems the most rugby-centric.

There are signs that two quarter-finals are taking place here all over the city and even a music festival on today to entertain fans before the match begins.

But here are a couple of my favourite rugby-themed decorations : a cat statue holding a sign reading 'try' and some rugby-playing scarecrows.

Teenager Jordan Petaia will play as a centre for Australia for the first time in Saturday's World Cup quarter-final against England.

The 19-year-old, who will win his third Test cap after previously featuring on the wing, partners Queensland Reds team-mate Samu Kerevi in midfield.

Will Genia is preferred to Nic White at scrum-half while David Pocock and Michael Hooper are in the back row.

Kurtley Beale has passed concussion protocols to start at full-back.

Australia:Beale; Hodge, Petaia, Kerevi, Koroibete; Lealiifano, Genia; Alaalatoa, Latu, Sio; Arnold, Rodda; Naisarani, Hooper (c), Pocock.

Replacements:Uelese, Slipper, Tupou, Coleman, Salakaia-Loto, White, To'omua, O'Connor.

Former England fly-half on BBC Radio 5 Live

If you bring these big players, and they are significant for you, you have got to use them. Slade’s position in the team dictates that Farrell can play at fly-half. It gives England a different look as an defensive outfit, and a very different one in attack.
