The Reds ran out 3-0 victors in front of 72,892 people at ANZ Stadium thanks to first-half goals from Daniel Sturridge, Alberto Moreno and Roberto Firmino.
Club legends Steven Gerrard, Jamie Carragher, Steve McManaman and Daniel Agger also pulled on the shirt once more in Sydney, appearing for 45 minutes apiece alongside their first-team counterparts.
The thousands of Reds in attendance were almost treated to a dream start when Gerrard latched onto Firmino's chipped cut-back and looked certain to score with the match in its infancy.
Unusually for the former captain, though, he skewed his effort over the bar from inside the box - much to his own dismay.
