It comes down to this, a clash between two giants of men's tennis.
On one side of the net is the world number four and Australian Open third seed, Stefanos Tsitsipas, bidding to win his first major.
Facing the Greek is a player regarded as one of the greatest to step foot on a court: Novak Djokovic.
Djokovic is chasing a 10th Australian Open championship and record-equalling 22nd major singles trophy.
The Serb, ranked fifth in the world, is competing 12 months after he was deported from Australia, which prevented him from defending the title he won in 2021.
Here's the lowdown on tonight's men's final.
When is the final?
The match will be played on Melbourne Park's Rod Laver Arena, starting at 7:30pm AEDT (Melbourne, Sydney, Canberra, Hobart) — that's 7:00pm in Adelaide (ACDT), 6:30pm in Brisbane (AEST), 6pm in Darwin (ACST) and 4:30pm in Perth (AWST).
How do I watch or follow the match?
The Nine Network is Australia's free-to-air broadcaster for the Australian Open.
The match will be broadcast on Nine and 9HD (channel 90), or in certain parts of Australia a portion of the match may be on GEM (channel 92).
You can also stream the match on 9NOW, or on Stan Sport.

What's on the line?
Aside from the honour of lifting the Norman Brookes Challenge Cup, Sunday night's victor will bank a cheque worth $2.975 million for their efforts.
The runner-up doesn't go home empty-handed, though, with $1.625 million their reward for making the final.
More importantly for the players, however, is the fact the winner will be crowned world number one when the ATP rankings are released on Monday, replacing Carlos Alcaraz at the top of the pops.
If Djokovic gets up, next week will be his 374th as number one, which will extend his record for most weeks in the spot.
Tsitsipas has never been ranked number one. If he takes over at the top, he will be the 29th player to lead the ATP rankings since they were introduced in 1973.
How did they get here?
It has been a drama-packed run to the final for Djokovic.
He faced media scrutiny about the extent of his hamstring injury, while also admitting to being distracted by the attention surrounding the incident involving his father.
After three scratchy performances on court, Djokovic hit his stride in the fourth round with his straight-sets thrashing of Australian hope Alex de Minaur.
He then outclassed fifth seed Andrey Rublev in the quarterfinals and comfortably got past unseeded Tommy Paul in the last four.
Tsitsipas has encountered little trouble in reaching the final, with his only true test coming when he was taken to five sets by 15th seed Jannik Sinner in the fourth round.
He should have wrapped up his semifinal against 18th-seeded Karen Kachanov in straight sets, but still got home in four.
Who wins?
Although Tsitsipas is hardly a ranked outsider, Djokovic deserves to be the favourite.
He has stepped up a gear in the second week of the tournament, and his form is arguably as strong as it was during his nine successful Melbourne Park campaigns.
The hamstring injury does not seem to be troubling the 35-year-old, but it remains to be seen how his preparation for the final has been affected by the emotional toll he has encountered in the wake of his father's incident.
Tsitsipas has the ability to win a major, with a solid serve, excellent groundstrokes and versatility in his game plan.
How he handles the occasion is a question on the lips of tennis observers, given he is playing in only his second final of a major, while Djokovic is in his 33rd decider.
When have they played each other before?
Djokovic leads the head-to-head meetings 10-2.
Tsitsipas's two wins came on hardcourt — in Toronto in 2018 (the first time they played each other) and in Shanghai the following year.
Djokovic has won the past nine matches between the two, which includes their gripping five-set final at the 2021 French Open.
Tsitsipas won the first two sets at Roland-Garros, before Djokovic fought back to claim his second French Open crown.
