Wales' Brent Cockbain will be looking to restore family pride against England at Twickenham.
Australia has been starved of rugby success against England over the past four years but Wallaby World Cup winner Matt Cockbain will have cause to celebrate this weekend if Wales can emulate Ireland and topple Sir Clive Woodwards team.
Australia last beat England in the 1999 Centenary Test, losing all five subsequent meetings, including the 2003 World Cup final.
Cockbain, currently playing Celtic League rugby for Cardiff Blues, has felt the pain of defeat as much as anyone, yet his younger brother Brent could help ease some of the hurt.
Brent, born in Coffs Harbour, Australia, but Welsh-qualified through residency, will win his ninth cap against the reigning RBS 6 Nations champions.
He has never played at Twickenham before, but lines up in a Welsh side hoping to end 16 years of failure on Twickenham's turf.
Cockbain, who made four appearances during Wales World Cup campaign, including the quarter-final defeat against England, is determined to make life difficult for Woodwards world champions.
But he also knows that Wales will at least have to gain set-piece parity following a disappointing scrummaging display against France.
There is no doubt about it that France have got a very good scrum, he added.
We didnt crumble against them, we just slowly creaked, and should have got rid of our ball long before our front row was in trouble.
England have got to be favourites in this game. They have a good well-drilled set of forwards, they are at home and they are going to be tough opponents.
Ireland produced a sensational performance against them in the line-out. They put England under pressure, and we saw a few cracks there.
Those cracks might not be as evident this week, but if they are, then weve got to make the most of it.
Its very difficult to play if you dont have the ball, so if you can take it off them in the line-out, thats one part of the set-phase. If you are losing your own ball, then it affects you around the pitch.
We will have to go in there flying on Saturday. England lost last time out, so they are going to come out flying.
