High-risk domestic violence offenders will be fitted with GPS tracking devices for the first time in NSW to restrict their movements to ensure they do not come within designated exclusion zones.

To avoid situations where they could inadvertently cross paths with an offender in the community, victims will be given the option to carry their own GPS unit which would alert authorities should the offender come within a certain distance.

The victim would then be contacted by authorities and advised of the imminent danger, under a trial being launched by the NSW government.

The measures form part of a $300 million package to protect women in this month's state budget, to be announced by the Minister for the Prevention of Domestic Violence and Sexual Assault Pru Goward, and Police and Justice Minister Troy Grant.
