The meeting was due to take place later this month but has been postponed until September.

More than 300 people have been invited to the two-day conference.

The summit will include sessions on financial security, policing and justice responses, and sexual violence.

Speakers will include Australian of the Year Grace Tame, Prime Minister Scott Morrison and Sex Discrimination Commissioner Kate Jenkins.

Aboriginal and Torres Strait Islander Social Justice Commissioner June Oscar and eSafety Commissioner Julie Inman will also address the conference.

Women's Safety Minister Anne Ruston said attendees would have diverse backgrounds and broad experience.

If the face-to-face summit cannot take place on the new dates in September it will be held online.

Georgie Dent, who advocates on behalf of Australian parents, said the launch of the summit program was a positive step.

"However, we need further clarity about how and when matters related to women's economic security will be addressed by the national cabinet," she said.

Ms Dent said women's safety and economic security went hand-in-hand.

"A woman can only leave a violent domestic situation if she has the financial means to do so."

She wants federal, state and territory governments to reform childhood education, paid parental leave and low pay for feminised workforces in aged and disability care.
