Marin Cilic was denied by Andy Murray in his first Australian Open semifinal eight years ago and another Briton now stands in his way on Thursday of making the final.
The six-seeded Croat was the beneficiary when world No 1 Rafael Nadal retired injured for only the second time in his 264 Grand Slam matches in the fifth set of their titanic quarter-final Tuesday.
It opened the door for the 2014 US Open champion to make his fifth Grand Slam semifinal, in sharp contrast to Kyle Edmund who is in his first after an extraordinary run in Melbourne.
Edmund, ranked 49, is the only British man in this year's field after five-time finalist Murray's injury withdrawal before the tournament.
The introverted 23-year-old Yorkshireman is only the fourth British man to get this far in Melbourne following his upset of world No 3 Grigor Dimitrov in the quarters.
He has kept a lid on his expectations during his mind-whirring charge through the field, but has impressed with his penetrative serve and booming forehand during his giant-killing run.
"I don't think about the fact that I'm going to win it. I think the next match is in my head. I believe I can win that, like the last one and every match," Edmund said.
"I've gone in there knowing where my game is at, knowing what I want to do on court, not taking anything for granted.
"I go in there, do what I need to do, play my game as best as I can, then move on to the next one. Match by match, that's key for me really, not thinking too far ahead."
He will fancy his chances against Cilic, despite losing his only match to him in two sets in Shanghai last year.
Cilic is bullish about his form heading into the business end of the tournament, having got past 10th seed Pablo Carreno Busta and Nadal to play off for a spot in Sunday's final.
"I'm extremely pleased with my own game. Even in the other matches before the Nadal one, I played great tennis. Very high level," Cilic said.
"I want to keep going with my own game and try to lift up, keep pushing as much as I can."
Cilic, who lost to Roger Federer in last year's Wimbledon final, has been serving impressively with a total of 96 aces and a fastest serve clocked at 215km/h (180 mph).
Cilic sees facing the unseeded Edmund as a great opportunity to make his third Grand Slam final and first in Melbourne.
"Kyle has had an amazing run, winning a lot of tough matches and playing great tennis," Cilic said.
"For me, obviously on the paper it's probably easier to play him than Rafa. But still he deserves a lot to be here."
