Defending Australian Open champion Kim Clijsters and 2008 winner Maria Sharapova said their vast experience more than made up for a lack of match-play heading into the year's opening Grand Slam.
Both Clijsters and Sharapova, along with five-time champion Serena Williams, have been nursing injuries in the lead-up to the Open.
Sharapova withdrew ahead of the season-opening Brisbane International with an ankle problem, while Clijsters and Williams both pulled out during the event after suffering on-court injuries.
But speaking after her 6-1, 6-2 third round win over German Angelique Kerber on Saturday, Sharapova said she wasn't concerned about her lack of match practice leading into the Open.
"I think you just have to take it as, OK, you go into an event, whether it's a Grand Slam or anywhere else in the world, if you're committed to playing that tournament, you have to be ready from the first match," she said.
"Sometimes you have to be realistic in terms of knowing that your level might not be exactly where you'd want it to be in the first round and you're going to be a bit rusty.
"But ultimately you have enough experience, you certainly played enough matches, it's just about hopefully getting through this one, getting better."
It's an approach long espoused by Williams and her sister Venus, who play a limited number of tournaments but often threaten at the Grand Slams.
Clijsters, 28, said her age and experience counted for a great deal at major tournaments.
"I think when you're a little bit older you're capable of setting your mind to what it is like to play a match again," she said after her win over Daniela Hantuchova on Friday.
"You have your routines. You have your game that you know that you're going to stick to.
"When I was younger I needed to play those matches to kind of get a feel for how I had to play and what my coach wanted of me, and those kind of things," she added.
"Now I know out there, even after two years off when I stepped out there, when I got out on the court, I knew what my game was, and I didn't need a lot of the matches to find that again.
"OK, you need to get used to the emotions and the pressure and the stress a little bit, but when it comes down to finding your own confidence, that's there. You've done that so many times and been in big situations so many times."
Despite their lack of recent matches, Sharapova and Clijsters have been in impressive form this week, neither dropping a set on their way to the fourth round.
Sharapova broke Kerber three times in each set but had to battle in the second as the German 30th seed lifted her game.
"I felt like I was aggressive enough. In the first set I didn't give her a chance to do what she likes," Sharapova said. "In the second set, it became a bit more of a battle, but I felt like I stepped it up when I had to."
