Australian No.1 Bernard Tomic will make his debut at the Hopman Cup this year with the event at the new Perth Arena for the first time.
Serbian former world No.1s Novak Djokovic and Ana Ivanovic will also take part in the mixed team event.
"I can't wait to play against the top players in the world and get guaranteed three matches of a high standard - something great before the Australian Open," said 19 year-old Tomic, the world No.49.
"I think where Davis Cup has helped me is playing the doubles and singles a lot in practice and the opportunity to play mixed doubles is something new for me. I can't wait to get on the court and help Australia win," Tomic said.
New Hopman Cup event director Steve Ayles announced Tomic and Team Serbia - reigning Australian Open champion Novak Djokovic and Ana Ivanovic - as the first players confirmed for the 2013 event.
"I'm very pleased to announce that world No2 and current holder of two of the four Grand Slam titles, Novak Djokovic, will return to Perth for 2013," Ayles said.
"Novak loves this event - he's coming back for the third time in the past five years - and he's very excited about the new venue and getting the best possible preparation for the Australian Open."
"I love the atmosphere," Djokovic said. "You have lots of great players taking part in the tournament so it's great preparation for the first grand slam of the year.
"I've reached the finals on two previous occasions so I sincerely hope that now this time, with Ana, we can actually win a trophy."
Mr Ayles, who was courtside at the Perth Arena today with Tourism Minister Kim Hames and Sport Minister Terry Waldron, said the State Government had done a fantastic job with the venue and he was excited by the prospect of growing the event.
“For the first time Hopman Cup will truly replicate grand slam playing conditions, making it even more attractive to the world’s best players,” Mr Ayles said.
“Importantly, our spectators will also enjoy unprecedented comforts within the stadium, adding to the enjoyment of the world-class tennis."
The tournament kicks off on December 29 and runs through to January 5.
