The chastening 6-0 defeat to Brazil should sound the death knell for the continued reliance on yesterday's men, according to Goal Australia's Chief Editor Iain Strachan
The task of bringing through the next wave of Australia internationals should have started with the departure of Pim Verbeek in 2010.
Failing that, it had to begin after the remnants of the 'golden generation' missed their chance to win silverware by losing to Japan in the 2011 Asian Cup final.
But Holger Osieck didn't like the look of Australia's kids and he had a job to do - book a place at the 2014 FIFA World Cup.
The German did not see enough from the youngsters at club level or in their fleeting appearances in green and gold to be convinced they were good enough to feature prominently in the qualifying campaign, and that is why he kept faith with his OAPs.
The veterans did not let him down, and a ticket to the biggest party in the world next June and July was secured, albeit unconvincingly.
The legacy of that shaky, make-do-and-mend qualification campaign - one which threatened to come unstuck against Jordan, Oman, Japan and Iraq - was laid bare in Sunday's thrashing and Osieck's preparations for the World Cup lie in tatters. He picked his strongest possible starting XI for Sunday morning's game, and they were humiliated.
If the core of the team remains in place, the best that can be hoped for next year is to be something approaching competitive against the weaker teams in Australia's group - assuming there are any - and to try and avoid disaster against the heavyweight team they will inevitably be drawn against.
Because of Osieck's lack of faith in the next generation, it could be too late to draft in reinforcements and expect them to produce. Not because the ability isn't there, but because the message which has been drilled home to them, in years of being overlooked, underused or ignored, is that they aren't good enough.
The likes of Rhys Williams and James Holland, who play regularly at a good level in Europe, have been afforded isolated opportunities and then promptly discarded after one or two uncertain performances.
Given Osieck's track record of mistrust, it is no wonder they appeared unsteady wearing green and gold.
Even those who have impressed enough to break into the squad are not afforded a place in the starting XI.
Where was Mitch Langerak's debut, forecast by none other than the coach himself? Why not employ the energy of Mitch Duke to press Brazil's defence?
And if you don't like Brett Holman's decision to move to the Middle East, why reward him at the expense of Tom Rogic, a prodigious talent the team should be built around.
There is only one course of action open to Australia's coach. Osieck has to start picking younger, quicker players in every friendly between now and June 2014, and he must give them the confidence and support to perform on the biggest stage.
But if their first collective taste of competitive football is the 2015 Asian Cup, expect the Socceroos to bow out early on home soil, before attention turns - with considerable trepidation - to the qualification campaign for the 2018 World Cup.
Already three years overdue, rebuilding must start now, with or without Holger at the helm.
