A full-forward known for his accuracy in front of goals, Churchett was the league's top goal-kicker for four consecutive seasons from 1948 to 1951. In the second half of that sequence he kicked 105 goals and 102 goals respectively. He was also Glenelg's leading goal-kicker in an additional two seasons. Churchett represented the South Australian interstate team on seven occasions during his career.
While away in Melbourne on war service in 1944, Churchett played one senior VFL game with South Melbourne. It came in a win over Geelong at the Junction Oval where South Melbourne scored an unusual 8.30 (78) to 8.8 (56) — the biggest winning margin with equal goals in VFL/AFL history.
