They freed a person trapped in one of the vehicles just before 3pm.
An Ambulance Victoria spokesperson said paramedics assessed four patients and took two to Maroondah Hospital.
Community reports indicate some disruption to traffic around the scene.
In Monbulk, a single car rolled on Monbulk Road about 2.40pm.
CFA crews received reports of the vehicle on fire and someone potentially inside.
