My sister lives in Perth Western Australia and is in a very unhappy marriage. She married in Victoria in 1994 and has been in Perth with her husband and two children for approx. 7 years. She desperately wants to come home as the marriage has fallen apart and cannot afford to live over there as a single mother. She was told awhile ago that if she left the state with the children, her husband can have them brought back within 24 hours. Is this true as this is her home? What can she do?
