Minister for Women Michaelia Cash and Prime Minister Malcolm Turnbull have announced a $100m women's safety package aimed at combating domestic violence.

Mr Turnbull and Ms Cash were joined by domestic violence campaigner Rosie Batty and former Victoria Police commissioner Ken Lay in Melbourne today to announce the package.

"I believe this sends a very, very clear message to the Australian people that this government places respect for women and gender equality and domestic violence absolutely at the forefront of its agenda," Ms Cash said.

"The commitment of this government … is that all women should feel safe in their home, should be safe on the streets and should be safe online.

"I hope that is the mission of all of us across Australia."

Some key aspects of the new package are:

• $17m to expanding existing programs aimed at keeping women safe at the home, including improving access to CCTV and locks.

• $5m to the 1800 RESPECT hotline

• $2m to MensLine services

• $21m to help Indigenous women and those in remote communities

• A $12m trial with state governments to use GPS tracking for high-risk domestic violence offenders

• $5m to 20,000 mobile phones across Australia for women whose access to technology is compromised

• $5m to developing and improving the Safe Schools website

• Improved training for frontline services, including general practitioners, doctors, nurse, magistrates and police

• Identifying domestic violence hotspots

Mr Turnbull said disrespect of women was a key root cause of family violence and needed to be addressed.

"This is a big cultural shift," he said.

"Of course, the vast majority of men do respect women. But many do not.

"We must make it un-Australian to disrespect women.

"We must become a country which is known for its respect of women."

The prime minister also paid tribute to his predecessor Tony Abbott, whose government put the plan in motion.

Earlier, Ms Cash told Lisa Wilkinson on the Today Show this morning domestic violence is "absolutely a national emergency".

This year, at least 63 women and girls have been killed by men - the vast majority by partners, ex-partners or men they knew through a domestic relationship.

Three women in NSW in the past three days have died allegedly at the hands of males known to them, while a horror spate of incidents in Queensland further pushed the issue into the national spotlight.

Tara Brown, 24, died in hospital on September 9 after she was allegedly beaten by her former partner while trapped in her crashed car at Molendinar on the Gold Coast.

Just one day later, Katrina Lock, 49, was shot dead by her estranged husband at a McDonald’s in Helensvale, Queensland.
