Coach Sir John Kirwan is building up a formidable line-up for the clash at Twickenham which already includes former Wallaby Nick Cummins.
Along with Stevens, 2007 World Cup winner CJ Van der Linde and and Cheetahs duo Coenie Oosthuizen and Heinrich Brussow will take on the Wallabies forward pack.
Three uncapped up-and-comers named on Thursday include teenage prop Thomas du Toit (Sharks), flanker Michael Rhodes (Stormers) and veteran back row Jacques Botes, who will appear for the 270th and final time for the Sharks on Friday night.
The match is likely to be the last for South African-born England international Stevens at Twickenham after 44 caps for the national team. He retired from international rugby in 2012 with 44 caps including appearances at the 2007 and 2011 World Cups.
“I’ve always wanted to play for the Barbarians – it’s one of the brilliant traditions of the game. It’s all about how you play and that’s very good for the game,” said Stevens.
“I’m back at Twickenham as well so there will definitely be a bit of nostalgia for me and it is a fantastic place. The last time I played there was in the Aviva Premiership final and it was a nice way to finish even though it was tough to have lost my last game on English soil.”
Further names will be confirmed in the coming weeks for the match that has already sold 50,000 tickets.
