Surrey have appointed Michael Di Venuto as the successor to departed head coach Graham Ford.
Ford returned to his former job with Sri Lanka at the end of January, having got Surrey promoted back to Division One of the County Championship.
His replacement is the 42-year-old former Australia batsman, who enjoyed a successful Championship career - chiefly with Durham, and also including stints at Derbyshire and Sussex.
Di Venuto has been his country's assistant coach and lead batting coach under head coach Darren Lehmann for the last two years and led them on the one-day leg of their ongoing tour of New Zealand, with Lehmann unable to fly due to deep vein thrombosis.
Di Venuto, who has signed a three-year contract, told Surrey's official website: "It has been a huge honour and privilege to have worked with the Australian team but the chance to come to a club of the size and potential of Surrey as head coach was too big an opportunity for me to turn down.
"As someone who has always enjoyed the county game, I have followed Surrey's progress over the last couple of years and look forward to working with this talented squad of players."
Surrey director of cricket Alec Stewart added: "Following the departure of Graham Ford it was vitally important that we found another high-quality coach with a great work ethic and excellent knowledge of the English county game.
"Michael is a good people person and his 12 years of county experience will be invaluable. He is highly regarded within the Australian set-up for his ability to work with and get the best out of players both individually and collectively."
