(CNN) -- Wales coach Warren Gatland has made two changes to his team for Saturday's autumn rugby Test finale against Australia in Cardiff.
Wales coach Gatland makes two changes to his side for this weekend's Test against Australia.
Scarlets wing Mark Jones replaces Cardiff Blues' teenage sensation Leigh Halfpenny, with lock Ian Gough taking over from his injured Ospreys colleague Ian Evans.
Evans will not play again this season after suffering knee ligament damage during the 29-9 loss to New Zealand three days ago and he faces surgery during the next couple of weeks.
Jones, who has won 42 caps, gains only his second start of the autumn after a knee injury sidelined him for the narrow defeat against world champions South Africa 17 days ago.
One switch on the bench sees Scarlets scrum-half Martin Roberts in for Dwayne Peel.
Victory for Wales could see them climb from their present IRB world ranking of sixth -- while a win by 15 points or more could lift them into the top four ahead of Monday's 2011 World Cup draw in London.
Gatland added: "We want to play the best teams regularly in order to improve ourselves and raise our own standards. We want to achieve consistency, and any rise up the world rankings would certainly be a reflection that we may be going in the right direction.
"But the most important thing for everyone is to get a result if we can. That is an incredibly tough prospect, but on the other side of the coin there is no doubting we have an opportunity against the Wallabies.
"The statistics say they are a better team than us and they will rightly carry the favorites' tag, but we have the opportunity on Saturday to achieve something special out of this autumn campaign. It is a chance we do not want to miss."
