The state side have revamped their coaching team after Trevor Bayliss left to become Sri Lanka's new coach.

Thorpe will work alongside new head coach Matthew Mott in Sydney.

"This represents the next chapter of my cricket career and I intend to give it my all," said Thorpe, who won 100 Test caps before retiring in 2005.

"I'm absolutely delighted to be offered the position and very much look forward to the challenge."

The 37-year-old has worked with the New South Wales squad for the past two winters as a specialist batting coach and NSW chief executive Dave Gilbert described his promotion as an "exciting" opportunity.

He added: "To have a player of Graham's international experience working with our squad, particularly our young talented players, will be tremendous."

Thorpe made his Test debut against Australia in 1993, marking the occasion with a century at Trent Bridge, and went on to score 6,744 runs at an average of 44.66.
