Exeter have completed the signing of versatile Wallabies forward Dave Dennis on a three-year contract.

Dennis has won 18 caps for the Wallabies and will arrive at the Chiefs at the end of the season from the Waratahs. He will offer an option in the second-row and in the back-row and said ex-Chiefs and current Wallabies lock Dean Mumm influenced his decision.

"Dean was a great sales rep for you guys," joked Dennis. "Speaking to him he had nothing but positive things to say about the Chiefs and his time over in England. He told me a lot of about the history of the club and the direction the Chiefs were heading in.

"He also mentioned about how the club had a great academy system and how they had brought through a lot of the guys who are now starting regularly each week. I think that's important in any club to have local guys coming through and it's something we have done here at the Waratahs."

Dennis follows in the footsteps of Wallabies prop Greg Holmes and hot prospect Ollie Devoto in signing for Exeter ahead of next term.

"I'm really looking forward to the move," Dennis added. "I've had an unbelievable time with the Waratahs and I owe them so much for what I've done in terms of my career. It's a fantastic club and I've no doubt it will continue to flourish in the future.

"The opportunity, however, to try something new in Exeter was one I was wanted to do and having spoke to a lot of people about the Chiefs, all of them have been very positive and told me it will be a great move for me.

"Each year they seem to get better and better in terms of results and performances and the draw of playing a different style over in England was something I wanted to try. "As a player you want to keep challenging yourself in different environments and that will certainly be the case over there."
