Hassan Asif died in Melbourne today, one week after his family joined him.
The 25-year-old student made headlines last month after his family were initially denied visas to visit him as he received end-of-life care.
Immigration Minister Peter Dutton later confirmed the family had gained approval for their second visa request on December 23.
Mr Asif’s brother Rameez arrived in Australia with his mother on December 29.
Rameez Asif thanked the Australians who had supported his brother in his final days.
In a statement, he said it was “like a dream come true to be with Hassan”.
“We literally lost hope when our visas got rejected but we still made it to Australia,” he said.
“I have no words to describe how happy we were to be with Hassan. My brother got the best possible care. Thank you.”
A funeral service will be held in Melbourne on Thursday.
