Parrott, who has worked for the Coles Liquor Group for the past five years, will be based in the McLaren Vale and report to Steve Grimley, managing director of the newly-formed subsidiary Direct Wines Source Australia.
An Australian national, Parrott is a regular judge on the Australian wine show circuit.
Global wine director Justin Howard-Sneyd MW said: “Dan is a talented and highly respected buyer, who brings with him an extremely deep knowledge of the Australian and New Zealand wine industries. We are very pleased that he is joining our team.
“Our previous buyer for Australia and New Zealand, Thomas Woolrych, will now devote 100% of his time to his role as buying manager. Thomas’ ability to create winning wines is exceptional and I am delighted that he will be working alongside all the buyers to develop our wine range, both in the UK and around the world.”
