A Sunshine Coast woman is working to secure safe passage for three Afghan siblings who fear for their lives in Kabul.

Zanette Perinoni was approached by a young man from Afghanistan who she met while leading a refugee support group.

The Afghan siblings - two men and one woman in their twenties - are currently stuck in hiding in Kabul.

Ms Perinoni especially fears for the sister, who she says faces a life of servitude if she is discovered.
