Murderers would have to hand over their superannuation to victims and their families under a new plan promised by the Victorian opposition.

Opposition Leader Matthew Guy on Tuesday morning announced, if elected at the November 2018 poll, his government would implement a suite of reforms to give victims more rights in the justice system.

All but one of the dozens of proposed changes to boost victims' rights are recommended by a Law Reform Commission report released last year and commissioned by the Napthine government.

The Andrews government is still considering the report including the implications it will have on the Office of Public Prosecutions, Victoria Police and the courts, as well as how to fund some of the reforms.
