Barbarians coach John Kirwan has told Wales now is their time to lay down a marker to the world's top sides by beating Australia Down Under.
Kirwan's invitational side went down 30-21 to the RBS 6 Nations champions at the Millennium Stadium as Welsh rugby bade farewell to cap centurion Martyn Williams and record try scorer Shane Williams.
The Baa-Baas faced a largely second-string Wales side, with their likely starting line-up for next Saturday's first Test against the Wallabies having left for Australia prior to Saturday's fixture.
But eye-catching performances from debutant wing Harry Robinson, who scored a superb 60-metre try, and flanker Justin Tipuric ensured Wales maintained their 100% record in 2012.
The three-Test series against Australia will represent a stern examination of that winning streak, but the Welsh players and management have made it clear that they head Down Under bullish about their chances of beating the Wallabies in their own back yard for the first time since 1969.
And former Italy and Japan coach Kirwan, believes caretaker coach Rob Howley and his side are well-placed to give the injury-hit Australians, a tough test.
Kirwan said: "Wales are now a very good side. (Head coach) Warren Gatland has brought an edge to them at the breakdown, technically they are very good there, and they bring that bit of the Welsh game where they have that someone who can break the line.
"If there is a moment to win, it is now and it is very important that the northern hemisphere sides take these tours seriously.
"You cannot afford to go there and lose as it affects you mentally.
"Wales need to go down and win and keep growing the spirit they have got, I reckon it's going to be a very solid tour and I think they have a very good shot."
The Barbarians defeat ended their three-game tour which included victory over Ireland and a heavy defeat at the hands of England.
There are those who question the existence of the Barbarians in the professional game, but Kirwan says it is vital one of rugby's best-loved outfits continues to be embraced.
The former All Black said: "We have been speaking all week about our responsibility to a fantastic institution.
"It is right that the Barbarians fill this space in the season.
"We have 12 different nations in our squad, it is fantastic, it's pretty social, we go out for dinner together and we try and find a balance but you can see the quality of players that came out today.
"We let ourselves down a little bit against England but since then we have had two very good performances and that's the tradition of our game.
"When you see both sides clapping Martyn Williams onto the field for his 100th cap, that's our game.
"We need to keep the Barbarians going, that tradition of guys like (front-rowers) John Smit and Neemia Tialata spending their careers battling against each other and then playing together at the end of the season."
