Giant Wallabies trio Taqele Naiyaravo, Wycliff Palu and Will Skelton have earned Barbarians honours to play next month.
The Barbarians, to be coached by former Wallabies mentor Robbie Deans and and England World Cup-winner Will Greenwood, will face South Africa, the Czech Republic and Fiji in the space of a week in November.
It will be a Barbarians debut for both Palu, who retired from Wallabies duties with 58 Test caps after last year's World Cup, and the 140kg Skelton.
Waratahs winger Naiyaravo played against Samoa last year.
Also announced on Wednesday was veteran All Blacks World Cup-winning halfback Andy Ellis, with more players to be announced in the coming weeks.
