At the beginning of the twentieth century, more women began to enter the workforce; but they were usually paid less, even when they performed the same work. Today, best practice employers ensure that gender-based pay discrimination is not part of their remuneration system (see here: Gender Equality - Best Practice).
Pay inequality is still a ripe topic, however, and can be countered by various legal mechanisms. For example, the Australian Human Rights Commission can investigate and mediate complaints of gender-based discrimination, including pay. In more serious cases, the Fair Work Commission has the power make orders that men and women performing work of equal or comparable value will be paid equally.
