The oldest-ever year-ending world No 1 kicks off his season in the first Slam of the year next week.
Rafael Nadal was a beaten finalist last year when losing to Roger Federer but says he wants to go one better this year.
Nadal took two of the four Grand Slams in 2017 and finished the year top of the rankings, ahead of old foe Roger Federer.
But he ended in disappointment after picking up another knee injury and having to quit the ATP Tour Finals in London early.
Doubts have persisted over his health but he feels ready to go again – but admits last year he was at the max when it comes to getting up for it.
Nadal faces Victor Estrella Burgos in the first round in the first night session match on the Rod Laver Arena court.
“It’s impossible to be more motivated than last year or any year,” said Nadal, who can only face second seed Federer in another final if they progress that far.
“For me, the Australian Open … if you are not enough motivated, 100 percent motivated to play this tournament, probably you don’t love this sport.”
World number one Rafa Nadal embarks on a new era without his coach and uncle in the players’ box at the Australian Open but the Spaniard said he would always welcome advice from his lifelong mentor with open arms.
Nadal returns to Melbourne Park, where he lost a thrilling five-set final to long-time rival Roger Federer last year, hoping to continue his progress under new coach Carlos Moya.
Former world number one Moya will lead the Mallorcan’s team, having helped him back to the grand slam winner’s table in 2017 after a barren three years while preparing for Toni Nadal’s retirement.
Toni has departed to focus on his nephew’s tennis academy but Nadal said their relationship remained intimate and “easy”.
“He participates as much as he wants to participate. He’s my uncle,” Nadal told reporters at Melbourne Park on Saturday.
“He’s more than anything else. That’s it. Everything that he wants to do with me, I am happy with, no? It’s not about my decision. He has enough confidence with me, or I have enough confidence with him, to talk about anything I have to talk.
“It’s difficult to explain. But it’s part of my family … He loves me. I love him. It’s not about, you know, a professional relationship. It’s a familial relationship.
“In terms of professional things, I spoke to him few days ago, speaking about how the life is going, how the tennis is going.
“If I have something to ask, I ask him. If he has something to tell me, he calls me and tells me. No, it’s not a difficult situation. It’s a very easy situation.”
Nadal’s preparations have added to a sense of a journey into the unknown at Melbourne Park for the 31-year-old great.
He heads into his first round match against Dominican journeyman Victor Estrella Burgos without a competitive match since he pulled out of the ATP Tour Finals with a knee injury in November.
He missed warmup events in Abu Dhabi and Brisbane but had an exhibition match at the Kooyong Classic and another practice match with Dominic Thiem at Melbourne Park on Friday, complete with ball boys and a chair umpire.
The 16-times grand slam champion showed no sign of discomfort in defeating fifth seed Thiem and said he felt “good” and was “more or less” playing well.
A 17th grand slam title would bring him within striking distance of the record 19 held by Federer but Nadal said he had no extra need for motivation at Melbourne Park.
