Grey has kept the faith with the starting side from the seven point win, with captain Toby Macpherson leading the way.
Reds flyhalf Harry McLaughlin-Phillips retains his spot at flyhalf after having a hand in a trio of tries during the victory over the Welsh.
There has been a couple of changes with the bench, with Waratahs hooker Oniti Finau making his debut at the tournament.
Angus Staniforth also makes his return, with Grey reverting to the 5-3 bench split.
Staniforth crossed for a double off the bench during their opening match against Georgia.
The two teams faced off at the U20 Rugby Championship earlier in the year, with Argentina taking the 25-6 win.
Los Pumas managed the wet conditions to take the victory, outscoring the Aussies three tries to none.
England will face France in the Final, with Ireland taking on New Zealand in the third-place playoff.
France are looking for back-to-back titles, whilst the English are looking for their first since 2016.
