The 32-year-old has not played since his first-round exit at Wimbledon, going under the knife to correct long-term cartilage damage in his left knee.

Wawrinka had been experiencing pain in the area for eight months before having his operation and admits it was a mistake for him to carry on without the correct treatment.

He is now back practicing and although he admits his knee is still not perfect, he believes the time off has allowed him to recharge his batteries and is confident he will be ready for Melbourne, where he won in 2017.

"It has been a year since the 2016 Swiss Indoors in Basel, that I suffered knee issues," Wawrinka told reporters on Friday. "The only regret is that I didn't stop before the grass-courts season, which worsened the situation. At the moment my priority is to recover well from surgery.

"My knee is a little bit strict. I work hard physically six days on seven, but from the tennis point of view I am a little bit behind.

"The goal is to play Australian Open, even if I am not 100% healthy.

"Having had crutches was hard, but the break allowed me to take a rest mentally after years where I was always at the limit."
