Hick, who played 65 tests and 120 one-dayers for England, was appointed Cricket Australia's high performance coach in 2013.
Head coach Darren Lehmann paid tribute to Hick's abilities.
"Graeme worked with us during the recent ODI tour in the West Indies and we were really impressed with what he brought to the group.
"He is a very experienced player in all conditions and will bring a wealth of knowledge with him.
"With an ICC Champions Trophy, an Ashes Series and an ICC World Cup all to be played in England in the near future, his knowledge of those conditions will also be invaluable."
Wisden Cricketer of the Year in 1987, Hick acted as assistant coach on the recent West Indies tour while Lehmann took a break.
