Novak Djokovic channelled his halcyon days in a five-set classic to dethrone Jannik Sinner and become the oldest man to reach the Australian Open final in the professional era at a rocking Rod Laver Arena.
Four months before his 39th birthday, Djokovic showed he remains unbeatable on his day as he sent the double defending champion packing with a 3-6 6-3 4-6 6-4 6-4 win.
Djokovic will meet world number one Carlos Alcaraz in Sunday's decider, the Spaniard having fought off Alexander Zverev in the longest Australian Open semi-final.
Eighteen years after his first Melbourne crown, Djokovic will strive for a record-extending 11th against Alcaraz and the unprecedented 25th Grand Slam title that has eluded him.
