Defending champions France delivered a powerful statement of intent by outclassing Australia as Olivier Giroud equalled Thierry Henry's all-time scoring record for the national team.

France have lost a host of players in the build-up to the tournament, including key striker Karim Benzema, but made light of those setbacks with a thrilling attacking display after going behind.

Craig Goodwin gave the Socceroos a shock early led when he powered home a far-post finish after nine minutes but they then fell victim to France's firepower led by veteran Giroud and Kylian Mbappe.

Adrien Rabiot's header put France level after 27 minutes then he set up Giroud - standing in for Ballon d'Or winner Benzema who sustained thigh injury in training - for a simple finish five minutes later following a brilliant Mbappe backheel.

Mbappe was a threat throughout and got his first goal of this World Cup when he headed in Ousmane Dembele's cross after 68 minutes before turning creator three minutes later.

He delivered the perfect cross for Giroud to score with a header, equalling Henry's record of 51 France goals in the process.
