A group of women and children linked to the Islamic State terror group has been searched and their devices downloaded by police on arrival at city airports after returning to Australia from years in detention.
The so-called "ISIS brides" travelled from a refugee camp in northern Syria for families of killed or detained Islamic State militants.
The first group of two women and their children touched down in Melbourne shortly after 4.30pm on Tuesday, having flown with Qatar Airways via Doha.
