CRYSTAL Palace midfielder will be hoping to take his club form into the World Cup as he prepares to lead out Australia in Brazil tonight (Friday).
The Eagles skipper is set to captain Australia this evening in their Group B opener against Chile, having battled to be fit for the match in recent weeks.
And as one of the more experienced members of the squad, Australia will be hoping Jedinak can lead by example for his side in a difficult group that also includes both finalists from the last World Cup in 2010, Spain and Holland.
Another experienced member of the Socceroos' squad is former Everton man Tim Cahill, for whom headed goals have become something of a trademark, having scored 31 goals with his head during his eight-year stay at Goodison Park.
However the Australia talisman admits Chile will be wise to his game ahead of their World Cup opener.
As such, the 34-year-old, who moved to MLS side New York Red Bulls two years ago, knows he will have his work cut out to replicate that prowess in Group B.
And in order to make a similar impression this time round, Cahill believes extra vigilance from the officials is needed to keep any roughhouse tactics from Chile at bay.
"I know for a fact that they'll have someone, or a few holding and shirt pulling and things like that to put me off my game. But that's no different to what I've had in the past," Cahill said.
"It's a competition where a little nudge can change the way you head a ball or the way you attack a ball or even defend a ball.
"So it will be no different to the way we're going to be and for us we're up for every single battle. We're going to stand up and be counted. Hopefully the referees clamp down on it this campaign."
England know exactly how uncompromising the Chileans can be after succumbing to a 2-0 defeat last November – to the derision of the Wembley crowd.
And Jorge Sampaoli's side, who reached the second round under Marcelo Bielsa in 2010, proved they could hang tough with the world's best after narrow defeats to Germany and Brazil in friendlies this season.
One possible stumbling block is Arturo Vidal's fitness – he's battling against inflammation after knee surgery a month ago – but Cahill insists any suggestion the midfielder won't be ready is smoke and mirrors from the Chilean camp.
"[Saying Vidal is injured] may be a tactical advantage for them, maybe he'll show up on the day and play," Cahill added.
"So for us we have to worry about ourselves. Vidal is a player that brings a lot to their team but at the same time, whoever steps in can do just as good a job as he can for Chile.
"There are a lot of players we're focusing on other than Vidal and [Alexis] Sanchez, there are players who make up a whole team and have had a lot of success in the past."
