Novak Djokovic staged an impressive recovery to beat Dominic Thiem over five sets and claim his eighth Australian Open title.
Djokovic trailed by two sets to one and looked in physical difficulties but he withstood pressure early in the fourth set and hit back to win 6-4 4-6 2-6 6-3 6-4, denying Thiem a first grand slam title.
Britain's Joe Salisbury won his first slam trophy in men's doubles alongside American Rajeev Ram, the pair defeating Australian wild cards Max Purcell and Luke Saville 6-4 6-2.

Reid runner-up
Gordon Reid's bid to win a first grand slam singles title in men's wheelchair since 2016 ended with a 6-4 6-4 defeat by Japanese top seed Shingo Kunieda. It has nevertheless been a strong tournament for the Scot, who also won the doubles title with Alfie Hewett.
Laundry service
Salisbury has been supported throughout his victorious Melbourne campaign by mum Carolyn. And grand slam champions, it turns out, still quite like their mums to do their washing for them. "I wouldn't say I've been making her," said a rather sheepish Salisbury. "She has volunteered a few times. I didn't turn it down."
