Police have issued an AMBER Alert and are appealing for public assistance to help locate missing girl Milena Malkic.
The 2-year-old was last seen in the Springvale area on 15 June.
Police have concerns for her welfare due to her age.
It is believed she may be with her parents Nadia Malkic and Joshua Coates in the south eastern suburbs of Melbourne, Altona, Warrnambool, Stawell or the Gippsland areas.
Police have released an image of Milena, Nadia and Joshua in the hope someone recognises them.
They have also released an image of a vehicle similar to the one the family may be driving, a blue 2002 Ford Falcon with registration 1HZ 4SU.
Anyone who sights Milena, Nadia or Joshua or who knows of their whereabouts is urged to contact Triple Zero (000) immediately.
The Facebook AMBER Alert child abduction system was launched nationally yesterday to help ensure the safe and immediate return of children.
The initiative complements Victoria Police current protocols around child abduction providing an additional mechanism in support of traditional broadcasting mediums for this purpose.
