Following the Wallabies 2–1 series defeat to the British & Irish Lions on their 2013 tour and a record 41–16 defeat in the decider, Deans handed his resignation into the ARU thus ending his role as head coach of the Wallabies. During his six-year tenure, Deans coached the Wallabies on 74 occasions, winning 43 times, losing 29 and drawing twice. He won just three times against their main rivals, the All Blacks, and drew once in 2012. He holds a good record against the Springboks, 9 wins from 14, and led the Wallabies to a Tri Nations championship in 2011 and to 3rd place in the 2011 Rugby World Cup.
