The South West Rocks product opened the scoring, set up a teammate after a thrilling solo run and fulfilled his role in Australia's dominant 62-14 victory over Japan in the Oceania Under-20s Championship opener.

Triston, who lined up on the wing, had a dream start as he crossed for a try inside the first minute.

The 20-year-old crept up in support of fullback Isaac Lucas, who had thrown a dummy and broke the Japanese defensive line, and passed a short ball to Triston, who raced down the sideline before stepping back in field to score under the posts.

In the 25^th minute, Triston was back in the action as he showcased his ability to break a game open.

The utility back, who has played in two tournaments for the Australian Rugby Sevens side, picked up a loose ball, calmly jogged back in field before stepping off his left foot, turning on the jets and sprinting straight through a gap in the defence.
