A Sydney woman who is trapped in Lebanon facing adultery charges has been refused help with finding a "safe house" by the Australian embassy in Beirut.

Mahassen Issa, 29, a mother of two from Greenacre has pleaded for help, saying she has run out of money, has nowhere to stay and is being pursued by bounty hunters, but staff on behalf of Foreign Affairs Minister Julie Bishop said it is "outside the scope of their consular role".

Refused 'safe house' help: Mahassen Issa.

The charges of adultery were apparently triggered when Ms Issa's Australian husband registered their marriage in Lebanon and then made a complaint that she had travelled there and was with another man.

Ms Issa's family have publicly disowned her and a court order has been obtained prohibiting Ms Issa, under her married name Mahassen Abou Lokmeh, from leaving Lebanon. It was issued on July 24 by the Lebanese Office of General Security.
