Root and his team-mates also triumphed the last time they met Australia at the Birmingham venue, winning by 40 runs (DLS) in the Champions Trophy two years ago. Smaller boundaries at Edgbaston help their style of play with (Jason) Roy and (Jonny) Bairstow at the top and that's what they will want to exploit at the start of their innings.
Ashes rivals Australia won the toss at Edgbaston and chose to bat but were in deep trouble at 14 for three, with prolific opening pair David Warner and Aaron Finch, as well as Peter Handscomb, back in the pavilion.
Confirming the news, Australian head coach Justin Langer said Handscomb will be named in the side's Playing XI in place of injured Usman Khawaja for their all-important clash against the Eoin Morgan-led side. England lost to Australia comprehensively in their league match at the Lord's. "We have been playing with that knockout intensity for a period now". New Zealand didn't really do itself justice in its first appearance in the title match, bowled out for 183 and then seeing Australia knock off those runs in 33.1 overs. England are slight favourites despite losing to Australia during group play.
The transformation has been impressive, with England climbing to number one in the ODI rankings under the astute captaincy of Eoin Morgan. Their opponents in this semi-final have been consistently better in this World Cup and beat England comprehensively two weeks ago.
Although Australia defeated England by 64 runs in the group stages of the tournament, Plunkett - who wasn't selected for that match - feels that result came at a time when the team "went into our shell a bit" after dwelling on previously disappointing results.
He has taken wickets in every game, including the crucial scalps of Virat Kohli, Chris Gayle and Quinton de Kock.
The fastest man in the competition, Jofra Archer, has bludgeoned his way to 17 wickets at an average of 22.76.
Eoin Morgan has been at the helm of England's revival as a one-day worldwide side, leading them to the top of the rankings and to their first World Cup semi-final for 27 years.
Historically, Australia also have a much stronger record.
"For me, being involved in England squads of the past, I never expected to win a World Cup", Plunkett said.
New Zealand reached a second straight Cricket World Cup final after late half-centuries by Ravindra Jadeja and MS Dhoni narrowly failed to make up for an unprecedented top-order collapse by India in its 18-run loss on Wednesday.
"Lord's, Cricket World Cup final".
