Sisters Anjumol and Asha Mathew (23 and 18) were killed in a horrific crash near Toowoomba in Queensland on Monday.
The sisters were killed instantly when their car crossed onto the incorrect side of Ipswich-Boonah Road colliding with a garbage truck.
Their siblings Elizabeth and Anumol are working with the Indian embassy in Brisbane to bring the women back to India to be buried in their home state of Kerala.
The family and friends got to know about the tragedy when the sisters failed to return home on Monday night.

"They were wonderful young people, and I think it's a very big loss for all of us personally," said family friend Ranjeet Vadassery.
"I was shocked, that was my first reaction. There were a lot of tears, and people rallying together in their grief," he told The Queensland Times.
Anjumol studied at the University of Southern Queensland and was a nurse at Lourdes home.
Asha had arrived in Australia just three months ago and was studying nursing at the University of Southern Queensland.
