"But the body was not ready because I had so many long matches", she said.
The current world No.1 and top seed said: "It's nice that it's happening".
"I am really happy, and I wish I am going to come back again next year and do very good again", an ecstatic Pavic said after the victory. "This tournament meant a lot for me".
Wozniacki, who has been US Open runner-up twice (2009 and 2014), achieved her major breakthrough by beating Halep 7-6 (7-2), 3-6, 6-4 in a punishing final contested amid stifling heat and across two hours and 50 minutes. Of course I am sad but Caroline was better than me. And while Halep would seem to have this one down cold on paper, if momentum alone was the key factor, Kerber would win in a landslide.
The Halep vs Wozniacki final will be broadcast on SONY SIX and SONY TEN2.
Halep has now saved match points in two separate matches at this Australian Open-five match points saved in all.
Halep: "Well, I'm feeling ok".
"From a year ago to today, I'm so proud my friend, so proud". I just wanted to give my best every match, which I did. "I was a little bit stressed". "I have no contract now, I'm still with no brand clothes", Halep said at the start of the 2018 Australian Open. "For sure. I was really exhausted".
"It's not easy to talk now but first of all I want to congratulate Caroline, she played awesome". "I think you just learn all the time".
The key lesson both women have learned in their years of knocking on the door is that Grand Slam titles have to be won with bravery and belief.
"Regardless, I think I've had an incredible career". It's fine. I cried, but now I'm smiling.
Halep should have won that point, with Wozniacki scampering from one side of the court to the other just to keep the ball in play before she produced a stunning cross-court backhand that caught her opponent on the hop and led to a smashed victor.
Wozniacki has topped the rankings for 67 weeks but long faced sneers that she is a pretender.
"This is a very emotional moment. I'm just waiting for the question, 'when are you going to win the second one?"
The final became compelling viewing with six breaks of serve in a gruelling first eight games of the final set. Whilst it is Halep whose weapons are far more damaging, this was clear to see in Halep's win over Kerber.
She closed it out with a blazing shot that all but knocked the racket out of Halep's hand. This is Halep's for the taking.
She is set to face the victor of Caroline Wozniacki vs Carla Suarez Navarro in semis.
It was the first time in the Open era that both Australian Open finalists had saved match points before reaching the final, also, so in some ways the pressure was off.
Wozniacki was not finished, though, and won three games on the bounce to end years of pain.
The final will be only the 17th time in Australian Open history that the number one and number two seeds have met for the title.
Australian Open officials say South Korean vehicle company Kia Motors has extended its partnership with the tournament for another five years. The BBC will also show highlights.
