The Socceroos were far too accomplsied for UAE, which had beaten Japan in a penalty shootout to reach the last four, in what proved a largely one-sided semi-final.
And Ange Postecoglou's men will fancy their chances of lifting the trophy by overcoming the Koreans - who beat them 1-0 at the group stage - at Sydney's Stadium Australia on Saturday night.
First half goals from defenders Trent Sainsbury and Jason Davidson underlined Australia's authority.
Sainsbury, who was grown in stature with each game at the tournament, got Australia off to the perfect start as he headed home a Massimo Loungo corner unchallenged in the third minute for his first international goal.
The early breakthrough re-affirmed Australia's belief that it had too much fire power for UAE, and it jumped out to a two-goal lead in the 14th minute when fellow defender Davidson also got on the scoresheet for the first time for his country, producing a fine left-footed finish with Mathew Leckie and Luongo involved in the move.
Ten Australians have netted the nation's 12 goals with Tim Cahill (three) the only multiple scorer.
Sainsbury's goal came in just two minutes 35 seconds, as many of the sell-out 21,079 Newcastle crowd were settling into their seats.
The centre-back's score came from a Luongo corner - and the magnetism of Cahill.
Cahill's presence attracted three UAE defenders to him, and Sainsbury trailed in behind, unattended, and placed a neat header to the right of the goalkeeper.
Just 11 minutes later, Davidson thundered a shot home and the Socceroos were headed for the final.
After a Leckie shot was blocked, the ball spilt to a scramble won by Luongo with a deft touch into the path of Davidson.
With time and space, the left-back cracked a low shot which beat a despairing dive from Emirates goalkeeper Majed Naser.
The perfect start came as the Socceroos dominated the Emirates, shifting the visitors around at will on a pitch softened by heavy rain throughout the day.
The UAE, despite eye-catching cameos from their star playmaker Omar Abdulrahman, rarely threatened against the cohesive Socceroos who turned in a complete performance - resolute defence blended with attacking menace, all underpinned by tireless work ethic.
The Emirates' best chance came from a speculative 25-metre blast from Ahmed Khalil in the 51st minute which had Australian keeper Mat Ryan beat, but sailed just wide.
The UAE will now remain in Newcastle for a play-off for third spot in the cup against Iraq on Friday.
And the buoyant Socceroos head for Sydney and their second consecutive cup final, after losing 0-1 to Japan four years ago.
