The international day for the elimination of violence against women is marked on November 25, kick-starting 16 days of activism against gender-based violence.
Parliament House will be illuminated orange on Tuesday night to recognise the event.
The federal government has announced an additional $41.8 million for 1800RESPECT, a hotline that provides confidential information, counselling and support for people experiencing domestic violence.
The free service available 24 hours was established in 2010 and has had a 3000 per cent increase in people contacting the service seeking help.
In 2023, the service launched an SMS channel followed by video counselling in 2024.
In the last financial year, the service received more than 342,000 calls, video calls, online chats and texts, allowing victim-survivors to seek support via the best medium that suits their needs.
More than 90 per cent of calls are answered within 20 seconds, and Social Services Minister Tanya Plibersek paid tribute to the frontline workers committed to protecting women and children.
"We're seeing some areas like intimate partner violence slightly decreasing, but we're seeing big increases in young relationships, under-18s ... so we need to keep evolving as this problem in our society evolves," she told ABC radio on Tuesday.
"I think anybody who discloses family, domestic or sexual violence needs an enormous amount of courage.
"Right across our community, there are people who are working every single day to keep women and children safe (and) I want to salute them as well."
Ms Plibersek has called on all governments and services to do better when it comes to protecting victims of domestic violence, following media reports about the way women who have been killed were failed by police and support systems.
The government wouldn't rest while there were still women and children impacted by gender-based violence, she told parliament.
Too many women in Australia were living in fear of men's violence, Women's Minister Katy Gallagher said.
"Services like 1800RESPECT are often the first safe door they can walk through to tell their story and get help," she said.
"This funding boost means more calls, more chats, more texts and more video sessions can be answered when women and their children reach out."
