[11] Molineux finished her strong maiden domestic season with a total of seven wickets at an average of 20.71 and was recognised at the 2017 Allan Border Medal ceremony by winning the inaugural Betty Wilson Young Cricketer of the Year Award.

[12][13] On 21 January 2020, Molineux delivered her first Player of the Match performance, taking 3/33 with the ball and scoring 80 runs with the bat in a five-wicket win against Tasmania at the TCA Ground.

[15] On the opening weekend of the following season at North Sydney Oval, Molineux claimed figures of 4/18 and scored 28 not out in her first Player of the Match performance, with the Renegades defeating the Adelaide Strikers by seven wickets.

[19] She was at the centre of a "thrilling" semi-final encounter with the Sydney Sixers at Drummoyne Oval, scoring 55 from 54 balls to "brilliantly take the chase into the final over".

[27] In March 2016, she played for the Shooting Stars—a team of Australia's best emerging female players—against Sri Lankan and English development squads during a tri-nation series in Colombo.

[35] Playing every game in Australia's successful 2018 ICC Women's World Twenty20 campaign, Molineux claimed four wickets across the tournament, including figures of 2/20 during a 33-run group match defeat of New Zealand to help qualify for the semi-finals.

[38] In February 2019, Molineux dislocated her non-dominant right shoulder while diving during a fielding drill at a training session, consequently ruling her out of an upcoming ODI series against New Zealand.

[45] After being presented her baggy green from Belinda Clark, Molineux went on to make a strong contribution throughout the match which ended in a draw, scoring 21 and 41 as a lower-order batter while also claiming bowling figures of 4/95 from 37 overs.

[49] Her timely inclusion for the semi-final against South Africa at the Sydney Cricket Ground—replacing an injured Ellyse Perry—proved crucial, as she dismissed Lizelle Lee early in the second innings before Australia held on to win by a narrow five-run margin.
