Australia will play off for fifth place in the World U20s Championships for the third straight year, after a 35-19 win over Scotland.
The Aussies have set up an epic playoff against New Zealand, who missed the semi-finals for the first time in this competition, after clinching a tough victory over the Scots.
A double to centre Sione Tuipolotu sparked Australia's late dominance, after a slow start turned into a formidable finish.
Australia had its first try in the third minute, through prop Tyrel Lomax, to gain the early advantage.
It took Scotland just three minutes to even up, though halfback Hugh Fraser, drawing scores level, and five minutes later they edged ahead with a second, though winger Robbie Nairn.
Both sides had numerous opportunities to attack off their set piece, kicking to touch deep in opposition territory.
Tuipulotu put the Aussies back in front with a 25th minute try, converted by Mack Mason.
The Aussies were left a man down after a yellow card was handed to Lukhan Tui, leaving them to hold off Scotland against a major challenge.
Two missed penalties from Scotland kept Australia ahead on the scoreboard at the half-time break, by just two points.
The Aussies had a major let off just after half-time but their relief only lasted four minutes, before Scotland’s Scott Cummings scored a try to put his side ahead once again.
Tuipulotu had his second in the 55th minute, finishing off a scintillating Australian attacking passage, to springboard the Aussies into the front once again.
Flanker Liam Wright added a fourth in the 68th minute, off some multi-phase play from Australia, with centre Jordan Jackson-Hope adding a cherry on the result in the 79th minute.
Australia’s lineout looked the strongest it had through the whole tournament, with lock Izack Rodda a standout in the second row.
Captain James Tuttle was industrious as ever, keeping his side ahead on the scoreboard and in the mental grind of the tight match.
Flyhalf Mack Mason slotted all five conversions in the match,making Scotland pay for some wayward penalty kicking earlier in the game.
