The Melbourne Rebels have added former Wallabies hooker Adam Freier to their playing roster for next year's entry to the expanded Super 15 rugby competition.

The Rebels announced Freier's signing on Tuesday, with the 30-year-old deciding to move on after nine seasons with the NSW Waratahs.

"The Rebels have demonstrated great faith in my ability, on and off the field, and that was a massive factor in my decision," Freier said after also recommitting to Australian Rugby Union for another two years.

"I will be repaying that faith by regaining my Wallaby jumper in their colours, something I have a burning passion for.

"I will continue to give my all to the Waratahs, who have supported me well over the last nine years, especially the last 12 months."

Freier, who began his Super career at the Brumbies, said Rebels coach Rod Macqueen was a big factor in determining his future.

"It was no accident that Rod formed a great culture at the Brumbies," he said.

"I was one of the young players that benefited from that culture. To now have the opportunity to help build one, with Rod - well that's something any player would love to be a part of.

"It's important to get it right off the field before you can advance on it.

"I am genuinely excited by the roster the Rebels are putting together and I look forward to exciting times in 2011."

Freier, who has played 99 games for NSW - many as captain of the Waratahs - plus 25 Tests for Australia, joins former Wallabies skipper Stirling Mortlock as one of the Rebels' major signings.

"Adam is one of the most respected players in Australian rugby," Macqueen said.

"He is very highly regarded by his peers. During our discussions with him, we were particularly impressed by his commitment to ensuring the Melbourne Rebels are successful."

Freier, who has yet to play a game this year due to off-season back surgery, is also the current president of the Rugby Union Players' Association (RUPA).
