The nation's leaders are set to unite to help stop violence against women.
Prime Minister Malcolm Turnbull and Opposition Leader Bill Shorten are expected to be among federal MPs at a White Ribbon Day breakfast at Parliament House on Tuesday.
The White Ribbon organisation aims to encourage men to play a role in ending violence against women.
It also aims to raise awareness about domestic violence, types of abuse, signs to look out for and ways bystanders can intervene.
On average, one woman is killed every week in Australia by a current or former partner.
White Ribbon's chief executive, Libby Davies, seized on the recent shock allegations of sexual harassment against the likes of Harvey Weinstein and Kevin Spacey and names such as Don Burke.
"Women have kept quiet out of fear of losing their jobs, and this silence from all sides has enabled the abuse, harassment and violence to continue," she said.
Ms Davies pointed to her organisation's efforts to change workplace culture - 122 businesses had already been accredited, covering 600,000 people.
"Organisations need to respond to and prevent abuse and violence against women, whether it occurs inside or outside their workplace by supporting women and holding perpetrators to account," she said.
