Former Wallaby and Waratah Scott Bowen (Easts head coach) and former Waratah and Italy Test lock Mark Giacheri (Randwick head coach) are assistant coaches.

Jeffs said his first goal is to unify the clubs and region behind the new Sydney representative team.

The clubs aligned with the Sydney representative team are Eastern Suburbs, Illawarra, Randwick, Southern Districts and Sydney University.

"There's a lot of history and success between the clubs that make up the Sydney team and we want to build on that tradition to create another level of accomplishment," said Jeffs.

"My first priority is to get all parties working together and we're off to a good start with Scott and Mark on board as coaches."

Bowen said Jeffs brings a unique set of skills that will benefit the Sydney team, which will play home matches at North Sydney Oval.

"Col is an expert in pulling teams together with limited preparation as he's done extremely well with Country," said Bowen.

"He'll also bring a fresh perspective to the Sydney environment and I think he'll bring everyone together quickly."

Fellow assistant coach Mark Giacheri also endorsed Jeffs's leadership.

"I'm really excited to be involved with Scott who I played with and against and I'm very much looking forward to working with Col who has impressed me with his experience and knowledge and I hope to learn a lot from him," Giacheri said.

Waratahs head coach and member of the coach selection panel Ewen McKenzie said the coaching trio is an impressive mix.

"The organisational skills and coaching abilities of Col Jeffs are exceptional and when combined with the experience and local knowledge of Scott and Mark, I think the Sydney team is in good hands," McKenzie said.

"They are very committed to getting the off-field part of the team right which is extremely important in a start-up team."

The head coach of the Western Sydney based team is expected to be announced within a week. The Central Coast based representative side has already named its head coach in John McKee.
