Another brazen scam targeting migrants has been uncovered in Melbourne.

The Australian reports that a scam in which migrant women paid up to $3000, and studied for up to a year, only to be handed fake childcare qualifications has been uncovered in Melbourne.

The report states that up to 100 women are thought to have received fake Diploma in Children's Services qualifications in the scam, which ran from 2010 to 2013 and targeted the city's Somalian community.

The women were given work books and were duped into thinking they had enrolled in a course at a reputable training organisation.

"These women genuinely believe they have completed the work, and at the end they receive a certificate...A lot of these victims have then started to seek employment, or promotions, within the childcare sector and it is then discovered their certificates are fraudulent. Detective Senior Constable Kate O'Neill told AAP.

Women affected by the scam are urged to contact police as there is an offer to complete their training legitimately.

A 36-year-old woman has been arrested in relation to the scam.

She will be charged on summons for allegedly obtaining property by deception and making false documents, according to The Australian
