Sydneys’ burger-and-booze-slinging funster Mary’s is offering women 15.3 per cent off their bills today to highlight the disparity between women and men’s earnings. It is available at the Newtown and CBD venues.

“No-one likes being short poured,” Mary’s says on its Instagram, but unfortunately Australian women are, due to our nation’s 15.3 per cent gender pay gap. Today is International Women’s Day and in recognition of this we are offering 15.3 per cent off for all women."

That means ladies will receive $2.448 off a Mary’s Burger (making it about $13.50). And $9.945 off the whole fried chicken, the Larry Bird, which is usually $65.

"The discount, inspired by David Hernandez at Mojo Record Bar, is a humorous attempt to bring light to a ridiculous situation that is well past it’s use by date. The hope is that by figuratively and literally raising a glass to the 15.3 per cent discrepancy is one that will start a conversation. A conversation that should be kept in the light until sorted," says Mary's.

According to the Workplace Gender Equality Agency, the gender pay gap is the difference between women’s and men’s full-time base salary earnings, expressed as a percentage of men’s earnings.

It has hovered between 15 and 19 per cent for the past two decades. (It is a measure of women’s overall position in the paid workforce and does not compare like roles.)

It means men working full-time earn nearly $27,000 a year more than women working full-time.
