Jo-Wilfried Tsonga has become the latest high-profile name to sign up for the season-opening Hopman Cup event in Perth.
Tsonga will begin his 2013 campaign by representing France in the mixed team competition, alongside Mathilde Johansson.
Other players to be announced for the event, which is moving from the Burswood Dome to the new Perth Arena, on Tuesday included Spain's Fernando Verdasco and Germany's Andrea Petkovic.
Tsonga said: "It's really good because I will arrive really early to Australia (and) I will be able to play three matches to prepare for the Australian Open.
"I heard that they built a new arena similar to Rod Laver Arena, so it's going to be just perfect for me to play, it's going to be fun."
Novak Djokovic and Venus Williams were among those who had already committed to the event.
Djokovic, who will play with fellow Serb Ana Ivanoivc, said: "I've played Hopman Cup three times in the last five years and I love the competition there; I love the atmosphere.
"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."
Meanwhile, Australian stars Sam Stosur and Lleyton Hewitt have announced they will compete in the Brisbane International in the same week as the Hopman Cup.
The Perth tournament begins on December 29, with the action in Brisbane starting the following day.
