The Government is ganging up on the gangs.

It's set up a Gang Intelligence Centre, bringing together the combined strength of Social Development, Customs, Corrections, Internal Affairs, Immigration and Police.

The information gathered will be used to disrupt and dismantle illegal gang activities and to identify and support members who want out.

The wider cost of gang crime to the taxpayer was today put at $714 million by a Social Development report.

One initial piece of work has been case studies of gang affiliated families.

They show gang members are themselves disproportionately victims of family violence and other violent crimes. This is being repeated through the generations at significant cost to social services.

The case studies also show gang members are disproportionately responsible for serious criminal and drug crime and more than 30 percent of the total prison population is gang affiliated.

Three other significant gang action plans are a programme to combat the inter-generatinal nature of gang life, multi-agency taskforces to target drug trafficking networks and a second taskforce to strengthen the recovery of proceeds from crime.

The Minister responsible for Social development, Anne Tolley, says they'll also be strengthening legislation like allowing courts to stipulate 24 hour GPS monitoring on high risk offenders such as gang members. There will be interim freezing orders for cash thought to be illegally gained and firearm prohibition orders.
