Human Services Minister Dave Hancock says they can already share details in most cases, but they tend not to for fear they might violate privacy laws.
Hancock says everyone needs to work together to help children whose difficult home lives may be causing problems in classrooms or with the law.
The bill also proposes changes to other legislation to assist agencies helping kids in need.
Those changes would affect family violence prevention, maintenance enforcement and the work of the child and youth advocate.
The bill is to be introduced this week.
