Hassan Asif, 25, a student who had been receiving end-of-life care for skin cancer while studying in Australia, died on Wednesday morning at a Melbourne hospice.

He was reunited with his mother and brother just days earlier, after the Turnbull government backflipped on its decision to deny them visas, sparking a public outcry.

In a statement, Melbourne City Mission said Hassan's brother Rameez and his mother were with Hassan when he died, and "had been a constant and loving presence by his side since arriving in Australia" on December 29.

On behalf of his mother and family in the Pakistan city of Lahore, Rameez expressed thanks for the care and support Hassan received in Melbourne, and for the chance to be reunited with Hassan in his final days.

"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."

Rameez said many Australians connected with Hassan's story, which helped raise awareness of his family's initial visa problems.

The family has invited members of the community who wish to pay respects to Hassan to his funeral service on Thursday, January 7 from midday at Preston Mosque. Attendees should wear modest clothing.

Mr Asif had been receiving outreach palliative care but recently moved to a specialist medical facility when his condition deteriorated.

He was too sick to fly home to Pakistan, where he had once hoped to return and begin work as an architect.

He wished to spend his final days with his family, but the Australian High Commission initially rejected their visa applications.

The Department of Immigration said based on the information provided in their application, the pair were considered at risk of overstaying their visa.

Labor's immigration spokesman Richard Marles last month described the decision as "disgraceful and heartless" and called on Immigration Minister Peter Dutton to intervene.

After a public outcry in Australia and overseas, the government asked Mr Asif's family to reapply for their visas, which included information about their finances and support from the local Pakistani community during their stay. The visas were then approved.
