But an injury cloud over first-choice centre forward Tomi Juric prompted a recall for the 24-year-old and he has done enough to convince the former Netherlands boss of his worth.
These days, reaching that holy grail has become routine, replaced by grander ideas of not just participating in the World Cup but winning their way through to the pointy end of the tournament.
Australia have two chances to erase that record before arriving in Kazan for their tournament opener with France on June 16; this match and a June 9 date with Hungary in Budapest.
"When I left Australia when I was 15 it was always a goal of mine to make the under-20 World Cup", he said. During Postecoglou's a year ago in charge, he was used predominantly as a wing-back, but may be afforded more latitude to attack under Van Marwijk.
The 38-year-old forward was chosen on Sunday by coach Bert van Marwijk among 23 players set to play in Russian Federation for the Socceroos. He remains a formidable finisher and ready to produce when called upon, as showed when he rescued Australia with two goals to win the second leg of the Asian World Cup playoff against Syria in October.
"I told them as we started that this moment will come. He was honest, and as a player you want a coach to be honest, you don't want him to say something and then go and do something else". "And he's also a player who will not be nervous when he plays for 80,000 people".
"He's a special case".
But all in all we really should not complain too much about a solid all-round display against a top European nation even though the Czechs are in a transition phase after failing to qualify for the World Cup.
"I have been very pleased with the effort and application of all of the players during our time in Turkey, and in Austria", van Marwijk said.
