Andy Murray is seeded fourth at the Australian Open as he prepares to make his grand slam return after undergoing back surgery in September.
The Wimbledon champion and three-time Australian Open finalist was ruled out of the closing months of last season with the injury but will feature in this month's championship in Melbourne.
The 26-year-old has commented on his fitness in recent weeks after his return to the game saw him take on Stanislas Wawrinka and Jo-Wilfried Tsonga.
"I feel pretty good; a lot better than I did a few months ago. I just need to play more matches like this because the intensity's a lot higher than you can get in practice," he said.
"It was good to get two matches against top players. Everyone needs matches at this stage, especially me. It's been a perfect start and hopefully I'll get better."
The Scot has dropped only one place in the ATP world rankings during his time out and sits just under third-place David Ferrer.
The Wimbledon champion's route to a fifth final in six years will be blocked by the likes of world No. 1 Rafael Nadal and three-time defending champion Novak Djokovic but not until the semi-final stage.
Meanwhile, in the women's competition, British hopefuls Heather Watson and Johanna Konta eased through the opening round of qualifying with straight-set wins.
Watson beat Australian competitor Arina Rodionova 6-4 6-3 to progress to the next round where she will meet France's Stephanie Foretz Gacon.
The 21-year-old has begun her grand slam qualifying campaign on the back of a tough 12 months battling glandular fever.
"I was very nervous. I feel like in the middle I loosened up but my energy really dropped at the end because I think all the nervous energy had worn me out," she said.
"But I was able to close it out. I played quite well, I definitely can play better, and I think I'll play a lot freer in my next match.
"I don't know why I was so nervous, it's a while since I played in qualifying and I expect myself to do well and go far. I really like the tournament and play well on these courts so I think I'm putting too much pressure on myself."
Third seed Konta cruised through the first round of qualifying with a 6-2 6-1 victory over American Grace Min but Dan Evans is out of the men's draw after a 6-4 6-1 defeat to Marton Fucsovics.
The Australian Open 2013 begins on 13 January.
