The young Dragons have run out 54-16 winners over the Wests Tigers in their NYC clash at ANZ Stadium, Olympic Park on Saturday afternoon.
A hat-trick to Jason Gillard and Tristan Sailor, and a double to Matheson Johns sealed St George Illawarra's fourth win in the past five weeks.
The Dragons controlled the game from the opening kick-off; with Johns pouncing on a Jackson Willis bomb in the second minute to earn an early 6-0 lead.
Four minutes later, centre Zac Lomax put his outside man Gillard into open space to push the score out to 10-0.
Two tries to five-eighth Sailor in the space of five minutes, both converted by Zac Lomax, extended the Dragons lead to 22-0.
The Red V continued to keep out in front of the clock, with Johns scoring in the left corner for his second try of the afternoon, before Lomax converted for a 26-0 lead after just 15 minutes.
A further two converted tries, one to Gillard (his second) and hooker Reece Robson only added to the Tigers pain, giving the home side a 38-0 lead four minutes before the break.
The Tigers managed to get on the board just before the break, with fullback Connelly Leumuelu putting left centre Peter Pakoti over in the corner to narrow the gap to 34 points heading into the break.
Converted tries in quick succession to prop Thomas Mikaele and lock Rhys Sciglitano broke the second half stalemate, putting the score at 38-16 with 15 minutes remaining.
A brilliant piece of footwork by fullback Steve Marsters opened up room for Gillard to score his third in the corner to push the lead out to 42-16.
Tries to Marsters and Sailor (his third of the afternoon) in the closing stages of the game saw the young Dragons run out 38-point winners.
