He was dropped from both the Test and state teams in the next season, but returned in 1983–84 as captain of New South Wales, winning the first of two consecutive Sheffield Shields that year and a McDonald's Cup in 1984–85. Wellham was recalled to the Australian team for the final Test of the 1985 Ashes tour and again for the final Test of the 1986–87 Ashes series scoring just 36 runs in these two matches. Wellham played 9 of his 17 one day international matches in the 1986–87 World Series Cup, the highlight being 97 against England at Sydney in a match more famous for batsman Allan Lamb hitting Bruce Reid for 18 runs in the final over to win the match.
