Kyle Edmund will carry British hopes when the Australian Open starts on Monday, with most of the leading names lining up for 2018's first Grand Slam despite a number of injury doubts.
Edmund himself has had an ankle problem but says he is fully fit to take on 11th seed Kevin Anderson at 00:00 GMT.
Ninth seed Johanna Konta begins against American Madison Brengle on day two.
Rafael Nadal, Novak Djokovic and Stan Wawrinka have all declared themselves fit after ending 2017 with injuries.
However, British number one Andy Murray is absent after having hip surgery last week and American defending champion Serena Williams is not yet ready to compete just four months after giving birth.
