The event, which will coincide with marches around the world, will continue on from the momentum of the past two years since US President Donald Trump was sworn into office - the original catalyst for the first Women's March held in Washinton D.C.
Focusing in on violence against women, 2019’s march aims to bring light to issues including domestic violence and rape culture, both of which were particularly prominent topics, and problems, for women in 2018.
Sydney's event will see media personality and host of Is Australia Sexist? Yumi Stynes MC. Featured speakers include Bri Lee, Rae Johnston, Bhenji Ra, Jane Brock and Aunty Norma.
There will also be performances by Des Fleurs, Malaika Green and Body Type.
How can I get involved?
If you're interested in participating in the march, all you have to do is turn up at the destination (in Sydney, Brisbane and Melbourne).
At each march, the hosts will be organising a "human chain" where participants will link hands as a show of solidarity.
Founder of the Sydney march, Kate Taylor, said joining hands was a symbol of solidarity and determination to keep forcing change.
“We have weathered the backlash and emerged unbroken to say: we want a safer world.”
While we wait for the event this weekend, here are some inspiring shots from last year's event:
