Opposition leader Matthew Guy on Wednesday said that under a government he leads jail would mean jail.

"At this election, Victorians will have a choice of more of the same from (Premier) Daniel Andrews and Labor or they can vote for the Liberal Nationals to get back in control of violent crime," he said.

Member for South West Coast Roma Britnell said family violence was one of the biggest law and order issues facing Victorians.

“We have to send a strong message that these crimes are wrong, and if you commit these offences and are found guilty, you will be sent to jail, no ifs, buts or maybes,” she said.

“The community expects people who commit serious crimes, like non-fatal strangulation, choking and suffocation, in a domestic setting, to be sent to prison.

“In many situations that isn’t happening. We need to get back in control of law and order and a Liberal Government led by Matthew Guy is committed to making it happen,” she said.

Mr Guy said that a Liberal Nationals Government will extend mandatory minimum jail sentences to family violence offenders.

He said the government's failed record on law and order spoke for itself and Labor’s approach of soft sentences and giving violent criminals ‘a slap on the wrist’ has failed Victorians.  

Mr Guy said that was why the Liberal Nationals had previously announced 11 violent offences in which a repeat offender would receive a mandatory minimum jail sentence. 

He said some of those 11 offences include situations of family violence involving crimes such as intentionally causing serious injury intentionally.

"Today, I announce that an elected Liberal Nationals Government will include three family violence specific offences to the current list of 11 mandatory minimum jail sentences," he said.

Those offences include breaching a family violence notice or order intending to cause harm or fear for safety, which will carry a maximum sentence of five years and if elected the Coalition would have a reoffender facing a minimum two-year term.

Another offence includes persistent contravention of family violence notice, which will have a maximum five-year sentence and a re-offender would face a minimum term of  three years in jail.

Non-fatal strangulation, choking and suffocation in a domestic setting, which will be a criminal offence punishable by up to 10 years jail would result in a violent re-offender facing a minimum term of six years imprisonment.

Mr Guy said the jail terms would be hefty and send a very strong message to anyone who thinks they can continue to defy the law and get away with repeat acts of violence, fear and intimidation.

Opposition spokesman for the Prevention of Family Violence Georgie Crozier said an elected Liberal Nationals Government would work through all of the Royal Commission recommendations with an urgent focus to provide safe, emergency accommodation and support for victims. 

"But we also need to send a strong and unambiguous message to offenders that the days of meaningless warnings and a ‘slap on the wrist’ are over," he said.

Opposition Attorney General John Pesutto said a Coalition Government would have a zero tolerance approach to family violence and if the tough new laws saved a single life or save someone from serious injury then  they would be worthwhile.
