The 43-year-old was last seen in the Ballarat area during April and has not been seen since.

Kobie's disappearance is considered to be out of character and police are now treating it as suspicious.

She is 168cm tall with a slim to medium build with long brown hair.

Detectives have released two images of Ms Parfitt in the hope someone may recognise her or have information regarding her current whereabouts.

Police are also urging anyone with any other information to contact Crime Stoppers on 1800 333 000 or submit a confidential crime report at www.crimestoppersvic.com.au
