The number of recorded offences in the state decreased by 1.6 per cent to 508,597 in the year to the end of September, the Crime Statistics Agency said.

However, the number of family incidents including violence, sexual offences and child abuse reported to police rose by 3.5 per cent, from 75,371 to 78,001.

Prevention of Family Violence Minister Gabrielle Williams noted the rise could be due to improvements in the recording of this type of crime.

"An increase in reporting rate also represents a larger number of people reaching out and asking for help," Ms Williams said, as she visited a service for vulnerable women in Frankston.

The Labor Government has invested $2.6 billion since 2017 to tackle family violence and will provide additional support over the holiday period.

Victoria Police often sees a spike in incidents between December and January and expects an additional 44 family violence cases every day, Ms Williams said.

Victoria Legal Aid said it is providing more support and help to Victorians affected.

A total of 39,086 legal services and 25,595 community legal education and information sessions for family violence problems were provided last year, its annual report for 2017/18 shows.

"There is an increased community expectation to identify and address the problem of family violence, and we know the importance of supporting parents and children with early advice and prevention services," chief executive Louise Glanville said.

It is the second consecutive year the overall crime rate has fallen, decreasing by 3.9 per cent to 7862 offences per 100,000 Victorians, the lowest rate since September 2014.

The number of burglaries and breaking and entering offences fell by 14 per cent to 42,170.

This is the lowest number in CSA records, which date back to July 2004.

"Crime is coming down, that does not mean our focus is any less," Police Minister Lisa Neville said.

"It shows with pressure, with the resources that Victoria Police need, we can make a difference to crime in our state, and we are going to continue to be relentless in our focus."

However, the Liberals said recorded offences under the Andrews Labor Government are up by more than 10 per cent, rising from 459,264 in December 2014 to 508,597 in September 2018.

Shadow Minister David Southwick said violent crime is worsening and drug use and possession offences are up 4.8 per cent.

"It is violent crime that Victorians are really concerned about, it is violent crime that continues to happen on our streets," he said.

"We want real answers, we want real action from this premier and what I can assure you that we are going to do under this term of government, is make sure we hold Daniel Andrews to account."
