Les Bleus went all the way in Russia four years ago, while the Socceroos are aiming to end a run of three successive group-stage exits.
Match preview
Since coming up trumps against Croatia on that rain-soaked evening in Moscow, France have added another major trophy to their cabinet in the form of the UEFA Nations League, but the negatives have far outweighed the positives for Didier Deschamps and co.
Having been eliminated from Euro 2020 at the last-16 stage, France are already guaranteed to relinquish their Nations League crown after a dismal period of performance in the 2022-23 edition, which very nearly culminated in an unthinkable relegation to League B.
Off-the-field scandals and countless injury problems have also plagued this France side, who already hold the unwanted honour of being the worst-performing defending champions at a World Cup after going out in the group stage in 2002 without a single win to their name.
However, as defending champions, France command a healthy amount of respect - even if their only win from their last six matches was a 2-0 home success against Austria - but history is certainly not on their side as they aim to become only the third team after Italy and Brazil to win back-to-back World Cups.
Indeed, the three defending champions that have come just before France - Germany, Spain and Italy - have all seen their next runs in the tournament end in the group stage, and not since Brazil in 2006 have the holders won their opening game of the competition.
The art of taking off a goalkeeper and bringing on a penalty-saving specialist is a difficult one to master, but Australia manager Graham Arnold pulled it off in the Socceroos' playoff final versus Peru, with Andrew Redmayne channelling his inner Bruce Grobbelaar in the shootout and helping to send Australia through.
Redmayne's efforts ensured that Australia would be present at the World Cup finals for the fourth time on the bounce, but the Socceroos have suffered three group-stage exits in that period and have only won one of their last nine games at the tournament - a 2-1 success over Serbia in 2010.
A round-of-16 berth in the 2006 tournament represents the Socceroos' best achievement on the biggest global stage so far, and while they flattered to deceive during AFC qualifying, Arnold's men head into their opening match on the back of five successive victories.
The Socceroos picked up a pair of friendly wins over New Zealand in September - winning 2-0 and 1-0 versus their Oceanic counterparts - but not since Tim Cahill's scorcher against the Netherlands in 2014 have Australia scored from open play at the World Cup.
France and Australia are familiar foes at the World Cup having met in the group stage four years ago too, which France won 2-1 thanks to Antoine Griezmann's penalty and an Aziz Behich own goal, and the Socceroos have only ever won one of their five meetings with Les Bleus, which came all the way back at the 2001 Confederations Cup.

Team News
Injury after injury after injury has been the theme for France even before the first ball has been kicked, with Saturday night's headlines being made after Karim Benzema was made to withdraw after picking up a thigh issue, having just returned to full training alongside Raphael Varane.
Deschamps is yet to name a replacement for the Ballon d'Or winner - he has until Monday to do so - but he has also been forced to swap Presnel Kimpembe and Christopher Nkunku out for Axel Disasi and Randal Kolo Muani respectively.
Olivier Giroud, Antoine Griezmann, Kylian Mbappe and Ousmane Dembele are expected to form the attacking quartet in Benzema's absence, and with Varane possibly not being risked for the opening matchday, Ibrahima Konate and Dayot Upamecano could line up at the back.
France are not the only ones to have been cursed on the injury front, as Hibernian striker Martin Boyle has been nursing a knee problem and has been unable to train with the Australia team in the lead-up to Tuesday's game.
Boyle has not been ruled out of the tournament yet, but Marco Tilio is on standby as a possible replacement, and Arnold otherwise has all members of his squad fit and raring to go - Ajdin Hrustic has reportedly been working as normal recently.
Stoke City defender Harry Souttar has affirmed that he is ready to feature on the opening matchday, despite a distinct lack of match practice since his ACL surgery, but Bailey Wright may be preferred from the off here as Souttar builds up his fitness.
France possible starting lineup:
Lloris; Pavard, Upamecano, Konate, Lucas Hernandez; Tchouameni, Rabiot; Dembele, Griezmann, Mbappe; Giroud
Australia possible starting lineup:
Ryan; Atkinson, Wright, Rowles, Behich; Hrustic, Mooy, Irvine; Leckie, Duke, Goodwin
We say: France 2-0 Australia
Not a single player from either team scored from open play at the correct end of the field when these two sides met four years ago, and that has been an area of weakness for Australia in World Cup games gone by.
