Terry has quit to move to OMD in Australia. He is joining the agency's Sydney office, where he will take a similar role. Terry is expected to work out a two-month notice period before departing.
Terry was promoted to the head of digital at the agency in April last year as part of a wider restructure instigated by Nick Manning, OMD's UK group chief executive. In this role he worked across the OMD Group, which includes OMD UK and Manning Gottlieb OMD.
Jonathan Allan, the deputy managing director of OMD, said that a replacement was being sought to fill the role. He added that the agency was looking at internal and external candidates.
