Cape Town - Stephen Larkham says the Wallabies winning streak over the Welsh mattered little as the teams prepare for their Pool A clash.
Australia are on a ten game winning run against the Welsh and will look for a victory on Saturday in order to avoid facing South Africa in the quarter-finals.
The Wallabies fly-half legend, who landed an extraordinary game-winning drop goal against the Springboks in the 1999 semi-final, is now Michael Cheika's offence coach.
"I wasn't a part of the regime until this year," said Larkham.
"I guess the focus we have going into this game is like any other - we have to make sure our prep is right.
"Michael (Cheika) took over at the end of last year and tried to change a few things within the culture and playing style and they are coming to fruition now.
"Those old games against Wales have no relevance to this weekend," added the 41-year-old.
Australia face Wales at Twickenham on Saturday, October 10.
The match kicks off at 17:45.
