Ailin's parents fled Iran in 2013, with their then three-year-old daughter.
Forced to flee following threats to their lives, they boarded a boat bound for Australia.
It was a time when nearly 17,000 people had made that perilous journey in the months before Ailin and her family, some died trying.
The Rudd government wanted to stop people smugglers.
The new law stated that if you come by boat without a visa and you're processed offshore, you can never permanently call Australia home.
