Radradra also scored a scintillating try at the London Sevens two weeks ago on the way to Fiji winning the tournament trophy.
In other backline changes, France-based Nemani Nadolo is on the wing, former Waratahs and Crusaders playmaker Ben Volavola is at flyhalf and Jale Vatubua will start at inside centre.
Kini Murimurivalu and Vereniki Goneva, who were try-scorers in Fiji’s 24-22 win over Samoa in the first round of the PNC last weekend, were named at fullback and on the right wing.
McKee said Fiji would need to be strong in the forwards to counter the powerful Georgia pack.
Meanwhile, Samoa coach Fuimaono Tafua made nine changes to his starting line-up for Saturday’s Test against Tonga.
Props Jordan Lay and Viliamu Afatia join hooker Seilala Lam in an all-new front row. TJ Ioane will start on the openside flank and Jack Lam will move from that position to No.8. Joe Tekori joins captain Chris Vui in the second row.
Among the backs, Dwayne Polata’vao will start at scrumhalf, Alofa Alofa at outside centre and Paul Perez on the right wing. Former captain Ofisa Treviranus has been named on the bench.
Assistant coach and former Wallabies fullback Chris Latham said Tonga would be hard to beat after their 16-15 loss to Georgia last weekend.
“They will have a few tricks up their sleeves but we have got to make sure that we look after ourselves, take care of the ball and play the game on our terms,” Latham said.

George Smith was, and indeed still is a lot of things to the game of rugby: ball thief, ruck monster, silky skilled, terrible kicker. But for all that Smith was and is to the game, ‘noted trainer’ is not often something associated with the great number seven.
