Following his retirement from playing in 1952, Oatey remained the coach of Norwood until 1956. In 1957, Oatey moved to West Adelaide where he coached until 1960, reaching the finals each year but never winning the premiership. Not involved in coaching at any team in 1961, Oatey saw the Bloods win the SANFL premiership, convincing him to return to the league. He went to Sturt, coaching there from 1962 to 1982, and leading the league team to 7 SANFL Premierships (a record at the time) including the famous five in a row from 1966 to 1970.
Oatey was one of the instigators of the greater use of handball, which is often solely attributed to the VFL's Ron Barassi, particularly within Victoria. He was inducted into the Australian Football Hall of Fame in 1996. Overall, Oatey coached 37 seasons in the SANFL, winning ten premierships (three with Norwood, seven with Sturt), reaching seventeen grand finals (six with Norwood, two with West Adelaide and nine with Sturt) and reaching the finals on 33 occasions. His ten premierships is still the record for the most premierships by one coach in top-level football.
Jack Oatey is the only person in elite Australian rules football history to coach over 500 wins. He coached Norwood, West Adelaide and Sturt to a total of 513 wins and five draws from a record 777 matches (153 of these were as playing coach for Norwood) for an overall success rate of 66.34%. He coached a record ten premierships.
Oatey was awarded Life Membership of the Norwood Football Club, was awarded Life Membership of the Sturt Football Club in 1971 and SANFL Life Membership in 1981.
In 1981 the SANFL inaugurated the Jack Oatey Medal to be awarded to the best player in the SANFL grand final, the first time an SANFL award was named for a still active coach.
A stand was named after him at the Adelaide Oval in 2014.
Oatey's eldest son Robert Oatey also played for and coached Norwood and later became a highly respected television commentator for Channel 7 and Channel 10's SANFL coverage in the 1980s, teaming with Bruce McAvaney, Ian Day, Peter Marker and Graham Campbell. Jack's youngest son Peter, was both a Norwood footballer and tennis player.
