Jean Lomax

Willson was a member of the Wellington 'B' team in 1930 and 1931, and played for the top Wellington team as a defender in 1932. In 1936, she switched from playing as a defender to the attacking third, and once again was selected to represent her province in 1936 and 1937. She also represented the North Island in 1936 and 1937. In 1938, her play was described as being "speedy and active" and she was said to be "shooting accurately".[8]

In 1936, Willson was first selected to tour Australia with a New Zealand national team the following season,[9] but the tour did not proceed.[8] In 1938, Willson was selected when a national side travelled to Australia and competed in the Australian interstate tournament in Melbourne.[8] At times, the New Zealand team struggled as the matches were played on grass courts under Australian rules, which differed from those used in New Zealand at the time, but they defeated Queensland 13–9, before losing to Victoria 16–48 [10][11] However, in an exhibition match played under New Zealand rules, the New Zealand team beat Victoria 19–5.[11] In New Zealand's remaining matches of the tournament, they were defeated by South Australia 14–47[12] and Tasmania 17–32,[13] before overcoming New South Wales 21–18.[14] Willson played in all of the matches except against South Australia.

Willson played in the single Test match, the first played between New Zealand and Australia, in Melbourne on 20 August 1938. New Zealand were defeated 11–40 in the match, which was played under Australian rules.[15]
