Aged 12, Wetherall played in
Jersey's first officially recognised
WT20I against neighbours
Guernsey for the
2019 T20 Inter-Insular Cup on 31 May 2019, although she neither batted nor bowled in the match at
College Field,
Saint Peter Port. Later that year she was in the Jersey team that finished second at the
France Women's T20I Quadrangular Series. Wetherall was among the Jersey contingent which went one better and lifted the trophy at the
2022 France Women's T20I Quadrangular Series. She was part of the squad which represented the island in the
2023 ICC Women's T20 World Cup Europe Qualifier. During the tournament Wetherall made her first WT20I half-century, scoring 57 not out against
Germany in an unbroken partnership of 101 with Analise Merritt, which was a new world record for a seventh wicket stand in the format. Wetherall's innings came off 40 balls and featured nine 4s and a 6 and made her the first player batting at number eight to score a WT20I 50. She also took WT20I career-best bowling figures of 3/15 against
France as Jersey finished third in the six-team event, narrowly missing out on progressing to the next stage of qualification. At the three-match
2023 WT20I Inter-Insular Cup with Guernsey, Wetherall played a key role as Jersey swept to a 3–0 victory. She made 21 in first game, took 2/8 from three overs in the second and then blasted 48 off just 30 balls in the third contest. During Jersey's tour of Northern Ireland in June 2024, Wetherall registered bowling figures of 6/18 in the second of two T20 matches against Ireland Women’s U19 Academy. In August 2024, Wetherall was among the British and Irish Roses squad selected to take on Team Europe in the inaugural Meltl Shield, a nine-match
T10 competition, held at
Roma Cricket Ground in
Rome, Italy. Wetherall was named in the Jersey squad for the T10 European Cricket Championship (ECC) in Spain and a two-match T20 series against
Gibraltar in December 2024. At the ECC event, she scored 15 not out to steer the islanders to a seven-wicket win over
Spain in the group stage. In the first match of the Gibraltar series, Wetherall took 2/9 off her four overs. She was part of the Jersey squad for the
2025 Women's T20 World Cup Europe Qualifier Division Two in
Rome. Wetherall recorded her career-best figures of 4/17 in the islanders' second match of the tournament against Germany. Wetherall was named player of the match at the annual
WT20I Inter-Insular Cup on 5 July 2025, after scoring 68 off 43 balls including three 6s and seven 4s as Jersey defeated Guernsey to retain the trophy at the
King George V Sports Ground in
Castel. She spent the 2025/26 winter season playing
grade cricket in Australia for
North Sydney Bears. In February 2026, Wetherall was named the 2025 Jersey Women's Cricketer of the Year. The following month she was picked to be part of a European team to play against the
Marylebone Cricket Club at
Lord's on 17 April 2026. ==Hockey==
