Many Aussie women feel that they are not treated equally in the workplace - and one in five of their male colleagues agree.
In fact, according to the new research, nearly half of all men admit their workplace is a "bit of a boys' club".
Commissioned by the Federal Government's Equal Opportunity for Women in the Workplace Agency, the study found widespread concern about the way Australian bosses were handing out promotions.
More than half of those surveyed - both men and women - said promotions were not always based on merit.
In the survey of more than 1600 people, it was revealed that more than a third of women thought that females had to "work a lot harder to prove themselves" and that their male colleagues were often promoted more quickly.
Agency director Anna McPhee said that the survey showed working women aged 16 to 65 - dubbed Generation F - still battled unfair obstacles in the office.
"Gender biases and old-school attitudes are preventing Generation F's full participation in the workforce," Courier mail quoted her, as saying.
And with labour shortages affecting many industries, she warned the sidelining of women's careers was not in the national interest.
"If women's ambition and career plans are recognised and supported they can make a major impact on Australia's productivity at a time when it is widely recognised that we need all hands on deck," she said.
