The Junior Boks played a controlled game with a clear plan, with their pack delivering a physical masterclass and providing their dangerous backs with a brilliant attacking platform.

Although they were sometimes undone by unnecessary errors, the SA U20s could not be faulted for their effort, attacking with intent and often ripping the Aussie defence to shreds and controlling the pace of the game by dominating possession.

Despite a few strong early carries, there were mistakes on the Junior Bok side, but they showed their intent in the sixth minute when Haashim Pead (scrumhalf) raced away for the opening try from a counter-attack that started deep inside their own half, with Siphosethu Mnebelele (hooker) putting in a good run.

Flyhalf Vusi Moyo's conversion made it 7-0, but the Aussies pulled one back a few minutes later when Sid Harvey (fullback) exposed a defensive lapse on the wing. The conversion wasn't over and the South Africans remained in the lead as they started to step up the pace.

The Junior Boks then delivered one body blow after the other in last 15 minutes of the half, with four tries putting them in firm control of the match.

Herman Lubbe (prop) bulldozed his way over after sustained pressure on attack before Siya Ndlozi (wing) scored two tries in six minutes, both from attacking breaks from the scrum, with Moyo converting all three to make it 28-5 with three minutes to go before the break.

The South Africans were not done yet and Cheswill Jooste (wing) went over on the stroke of half-time after some great hands. Moyo missed his first kick of the game, but at 33-5, it didn't make a big difference.

Haashim Pead scored two of the Junior Boks' 11 tries.

The Junior Boks then added four more tries in the first 12 minutes of the second half, to seal the deal with a superb display of attacking rugby.

Pead scored his second from an attack after a Wallaby kick in the 45th minute before Gilermo Mentoe (fullback) intercepted on the ground and raced 80m downfield to dot down shortly thereafter.

Two minutes later, lock JJ Theron smashed his way over after a great run by Xola Nyali (flanker) to bring up 50, and a few moments later Jaco Grobbelaar crashed over in the corner shortly after he replaced Theron.

Moyo converted three of these, and with 25-odd minutes to go, the Junior Boks led by 59-5, but it was 66-5 just before the hour-mark when Nyali broke away and ran 30m to score from a maul. Replacement flyhalf Ian van der Merwe made no mistake from the tee.

Australia managed to get more possession, but the Junior Bok defence held firm as Kevin Foote emptied the bench. The Junior Wallabies finally scored their second try with 10 minutes to go when Cooper Watters (wing) went over in the corner, adding a second a few minutes later as the heat started to take its toll.

Jaco Williams (replacement wing) had the final say though as he intercepted and scored from the halfway line to seal a superb victory for the Junior Boks.
