Harlequins duo James Chisholm and Harry Sloan helped England U20s make it two wins from two in this season's IRB Junior World Championship on Friday.
Chisholm, who came on for Joe Conlon after nine minutes, set up the second try as England beat Australia 38-24 in New Zealand.
There were two tries apiece for Henry Taylor and Nathan Earle and one for London Wasps' Gus Jones while Billy Burns kicked five conversions and one penalty.
Australia took an early lead with a try and conversion but the defending champions hit back with a quick double from scrum half Taylor, the second of which came when No. 8 Chisholm found him on the inside to dive over.
Australia made it 17-10 with a penalty before Earle powered his way over the line to give England a 24-10 advantage.
Australia hit back before the break, but England, who beat Italy in their opening match, started the second 40 with a bang as Jones dived over.
Again Australia came back fighting though, and scored to make it a seven-point game at 31-24 but Earle killed off the contest when he crossed for his second try.
Forwards coach Ian Peel added: "It was a really good test for us - both mentally and physically.
"The lads know they've been in a tough game; the forwards put in some excellent scrum work and our line out functioned well. We pressured them, stole some good ball and ultimately set up a strong platform.
“The breakdown was a big target area for us and I thought we came out on top, which is ultimately why we won the game.
"The matches come thick and fast, we’ve got a few bumps and bruises so we’ll recover well and get ready to go for Tuesday against Argentina.”
Meanwhile, Harlequins Academy U18s player Henry Cheeseman will make his England Sevens debuts in Lyon this weekend in the opening round of the FIRA-AER European Grand Prix Sevens Series.
England play Belgium (10am), Scotland (1pm) and Wales (5.06pm) in the group stage on day one.
