This is not an isolated case.

From that first link I gave in the thread:

In the year 2000, Shazad Kayani, an Australian Citizen from Pakistani background, doused himself in petrol and set himself alight in front of Parliament House, Canberra and died as a result. He had been waiting six years to bring his family, including his daughter who has a disability, to Australia. Since 1995, after arriving on a Visitor Visa and applying and being granted refugee status, Mr Kayani had tried to reunite with his family. All his efforts had come to nothing, largely because his daughter with the disability is considered to be "too much of a drain on the health system" with costs estimated to be around $750,000 over the girl's lifetime.
