's support for women "was genuine", following marches in early 2021. Mostyn commented that recommendations by Kate Jenkins, Sex Discrimination Commissioner, following the national inquiry into workplace sexual harassment, could be implemented and accepted.
Mostyn delivered a speech at the National Press Club, in November 2021, as president of Chief Executive Women, on economic recovery and post-pandemic recovery, describing how Australia can make "the most of its available resources and talent" by investing in care, for paid parental leave, childhood education and superannuation reform, as well as ensuring employees in the care industry, such as teachers, childcare workers and nurses, are receiving well-paid salaries, and respect within the workplace. She described how the pandemic had "left women exhausted and deepened their inequality, particularly in the workplace" and that much of Australia's "luck" had been due to the undervalued work of women.
She has reported on corporate Australia and the gender diversity within the top 300 companies, with 5% of women CEOs in the S&P ASX200 companies.
