Swansea flanker Jonathan Thomas will win his first test cap for Wales against Australia at Sydney's Olympic Stadium on Saturday.
Alix Popham, who is also uncapped, is named on the replacements bench in a new-look squad that includes six changes from the starting side who finished the Six Nations championship in March.
Mark Jones and Tom Shanklin are the new wings while Jamie Robinson is selected as Mark Taylor's centre partner.
Gareth Cooper starts at scrumhalf while an injury to Dafydd Jones means a reshuffle in the pack with Colin Charvis moving from flanker to number eight and Thomas winning his first cap.
