Matt Giteau doing his talking on the pitch

Matt Giteau has gladly rewritten his plans of earning money on the speaking circuit to help Australia to the brink of claiming a spot in the World Cup final.

Giteau celebrated his 100th cap with a man of the match performance in Sunday’s controversial 35-34 victory over Scotland and now faces a semi-final appointment with Argentina at Twickenham.

The 33-year-old has benefited from coach Michael Cheika’s demand to the Australian Rugby Union that they reverse a long-standing policy by allowing him to pick overseas players if they have made 60 or more international appearances.
