At the same time, Labor has pledged to build a domestic violence support centre in Sydney's southwest for migrant and refugee women.

The government's proposal aims to help get domestic violence victim-survivors into their own homes as they flee abusive relationships.

Premier Dominic Perrottet said his program would make a "real difference" in helping victim-survivors fleeing abuse into their own home.

"We know that safe homes lead to safe families," he said on Saturday.

Opposition Leader Chris Minns said it was hard starting a new life in Australia as a migrant or refugee but even harder for domestic violence victims.

He said one in three migrant and refugee women experienced domestic violence.

"New migrants need someone who can speak their language, understand their culture and be there for them when they are in danger and need their help," he said.

The proposed centre, to be run by community-based not-for-profit Settlement Services International, echoes similar support for migrant and refugee victim-survivors in Victoria and Queensland.

The centre would receive a total of $7 million in funding across five years.

Settlement Services acting chief executive Yamamah Agha said language barriers and inconsistent access to interpreters exacerbated domestic violence difficulties for refugees and migrants.

They were also less likely to report violence because of cultural stigma, lack of trust in mainstream services, financial insecurity or visa status.

"It's (Labor's proposal) going to be bridging a gap ... it's going to support women from refugee backgrounds not to fall through the cracks and offer a tailored way of support," Ms Agha said.

Under the government's proposal, the Rentstart Bond Loan eligibility criteria would be waived for people fleeing domestic violence so they could access interest-free loans for bonds.

Victim-survivors would also be able to access both the First Home Buyer Choice and First Home Buyer Assistance schemes, even if they previously accessed them with their abusive partner.

The choice program allows home buyers to elect to pay either a stamp duty or an annual land tax when they buy a home, while the assistance scheme provides concessions or complete waivers of stamp duty.

Women's Housing Company chief executive Debbie Georgopoulos said the proposal would help women not eligible for crisis accommodation or social housing.

"Having somewhere to go is actually the most important step in leaving a violent relationship," Ms Georgopoulos said.

The schemes would not be means tested which Mr Perrottet said was to ensure choice for everyone fleeing abuse.

He said government agencies would work together to confirm eligibility.
