Brumbies star Tom Banks, who shone at fullback in Friday's trial, Faingaa and Rebels pair Jack Maddocks and Jermaine Ainsley are the others in line to earn their maiden Test caps.
Captain Michael Hooper will continue his rehabilitation from a hamstring injury that he suffered in the final Test against Ireland while back-rower Pete Samu will re-join his Wallabies teammates this week after helping the Crusaders win a record-extending ninth Super Rugby title on Saturday night.
The squad will be revised after the camp in Cessnock this week with the Wallabies to reconvene next Sunday at a fan day in Blacktown in Sydney's west.
