Victoria police asked for public assistance to help find missing siblings, Bobbie-Jade May, Edward May, and Piper-Willow Maddy.
Children, aged 11, 9 and 9 months respectively, have not been seen since October 19 October. They believed they might be with their mother.
Concerns are held for the welfare of three children because of their age. They are known to often visit Bendigo and Shellfish areas.
