Based on a Victorian model, the packages are expected to cost $60 million in total.
Partners who exercise financial control in a relationship is an indicator of abuse, domestic violence organisation White Ribbon says.
The packages are designed to help women leave relationships and set up stable, permanent homes for them and their children.
"These packages are about helping people keep their life together in the most difficult of circumstances," the opposition leader said in a statement.
"(They're about) keeping the kids in the school they know, keeping the family doctor, being able to stay in work and study."
The packages won't be restricted to women with children; young people, temporary visa holders and members of the LGBTQI+ community will be able to access the funding as well.
Victoria rolled out flexible support packages in 2016, spending more than $64 million on more than 19,000 packages.
The federal government has also moved to provide support for women disadvantaged financially by ending an abusive relationship.
In November, the Minister for Women Kelly O'Dwyer announced a funding boost for family law services and initiatives to improve economic security.
