Statistics on Victoria Police's recently launched online news site, Victoria Police News, show an overall reduction of 4.7 per cent in Casey.

Acting Inspector Bruce Kitchen said the reduction came from better utilising resources to tackle problem areas.

Improved traffic management had led to serious road injuries down 30.4 per cent and fatalities down 15.4 per cent, he said.

"We're getting smarter in relation to intelligence and utilising all our units to address traffic problems."

He said a dedicated approach to specific crime areas was central to the reduction in burglaries (excluding residential), down 21.8 per cent; robberies, down 16.3 per cent; and property damage (graffiti), down 4.4 per cent.

Family violence attributed to much of the 5.7 per cent increase in assaults, he said.

"Police will not tolerate family violence. We're trying to break the cycle of family violence - much of it comes down to reporting it."

Thefts of, and from, motor vehicles experienced a 9.6 per cent increase.

Acting Inspector Kitchen welcomed the online news site, and greater accessibility to police data, saying it adds to the perception of police being open and transparent.

South Eastern Metropolitan MP Gordon Rich-Phillips believes the Brumby Government has a long way to go in Casey when it comes to fighting crime.

"Casey residents are at a greater risk of having a crime committed against them.... than they were 12 months ago."

The Police Association claims Casey is short of 126 police officers.
