Ms Lindsay, from Unanderra, suffered early childhood sexual abuse and was also raped at the age of 14.

She said certain things could "trigger" the past hurt, but she never expected it to come from our nation's leaders.

"The amount of anger I was feeling about everything I was seeing in front of me was palpable," she said.

"When you see the Prime Minister and other people within the Liberal Party use the language that was used about you to blame you as the survivor for what was done to you, that's heartbreaking."

Despite having a physical disability, "anger and passion" fuelled Ms Lindsay to co-organise a March for Justice at Lowden Square in Wollongong on Monday, which saw more than 150 men and women meet before joining thousands of others at Parliament House in Canberra.

They were among about 100,000 people to join protests around the country calling for change in the capital - for women to feel safe and supported.

"When people then turn on you because of your trauma - not because of something you did but because of something that was done to you, or someone tried to take from you - and they act like you're the bad person, it's basically heartless," Ms Lindsay said.

"We need women to feel not just safe at their work, on the streets and in their homes, but that they can safely go to the authorities and they will be supported through their reports and they won't be called out by ministers and be spoken down to."

South Coast Labour Council president Tina Smith said if sexual assault allegations were to arise in another workplace it would be dealt with very differently.

"They are our highest employement office in Australia and their culture is pretty bad, poor," she said.

"Everyone has an entitlement to work in a safe workplace, and women in particular given what we're seeing ... In another workplace there would be an investigation and processes to work out what happened."

The latest wave of action has been sparked by former Liberal adviser Brittany Higgins alleging she was raped while working in Parliament House in 2019; followed by allegations Attorney-General Christian Porter raped a 16-year-old girl in 1988, which he denies.

An inquiry examining workplace culture has been launched in the wake of Ms Higgins' allegations, but an investigation into the allegations surrounding Mr Porter has been rejected by the federal government.

Protesters are calling for all 55 recommendations of the Respect@Work report into sexual harassment in workplaces to be implemented and for increased funding for gendered violence prevention.

They also want an independent investigation into all cases of gendered violence and a federal Gender Equality Act including an audit of parliamentary practices.
