Police have issued an Amber Alert and need public assistance to help locate missing girl Milena Malkic.
The two-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 call triple zero immediately.
