In 1982, Miller was a quarter-finalist at the Sydney Outdoor tournament and lost in the doubles final of the New South Wales Open, partnering Cliff Letcher.[4]
In 1986, he started the season well by reaching the singles quarter-finals at Auckland but wouldn't appear on tour again until September, as a result of a benign tumour that he had to have removed from his vocal cords. During this time he wasn't able to travel overseas due to restrictions on his medication and he instead spent his time coaching at the Australian Institute of Sport.[5][6] He played for another year and a half, before retiring after the 1988 Australian Open.[4]
Coaching
Miller was the head development coach of Tennis Australia for seven years and later ran his own tennis program, IQ Tennis.[7]
