Luke Charteris admits Wales must improve if they are to complete the Invesco Perpetual Series with a victory over Australia.
Charteris played an integral role in the 33-16 win over Argentina at the Millennium Stadium on Saturday which saw the hosts run in three opportunistic tries.
Now the Newport Gwent Dragons lock believes Wales will need to be better against the Wallabies in Cardiff this weekend.
Charteris, 26, said: "I felt we did well. I enjoyed it and I certainly want to go out there again. It's been a tough month, we've all worked hard and everyone in the squad wants to be involved against the Wallabies.
"We managed to get a good win against a very good team, but we know we need to get better. If we want to beat the likes of New Zealand and Australia we have to improve.
"We're happy with the performance, we played well and dominated the game but there are still more gears we can go to and we hope we can show that against Australia next week."
Charteris was also keen to praise the Welsh front row, who were expected to struggle against the Pumas.
He added: "The front row was outstanding. I thought Paul James, Gethin Jenkins and Matthew Rees did really well. There was a lot of talk in the week about how they were going to run us backwards but we held our own.
Charteris put in a notable performance himself and made use of all of his 6ft 9ins frame to make the charge down which led to Shane Williams' first try.
Charteris added: "I did all the hard work and Shane just had to run it in! But it's something Ive been working on and lucky enough it came off.
"Shane is a quality player and world class. For the first try he could have run straight to the corner but he decided to beat four or five people just for fun. He's probably the only person in world rugby who could do that."
