Hundreds are expected to gather at Melbourne’s Family Violence Memorial for the vigil, organised by the Safe Steps Family Violence Response Centre.
The vigil will also mark Domestic Violence Remembrance Day.
At least 26 women have died from alleged gender-based violence in Australia this year, 11 more than last year.
Those women include Samantha Murphy, Rebecca Young, Hannah McGuire, Swetha Madhagani, and Molly Ticehurst.
“Domestic and family violence affects people from all walks of life and includes many forms of abuse and violence that are not always physical,” Safe Steps in a statement.
“The Safe Steps Candlelight Vigil is a call to action to speak up, lift the veil of silence that surrounds domestic and family violence, and reach out for support if experiencing, and/or perpetrating violence.
Tens of thousands gather for third day of protests against gender-based violence
A number of landmarks will also be lit up in purple across Melbourne to bring awareness to domestic violence including Flinders Street Station, Federation Square, MCG, the Royal Exhibition building and the Police Academy.
