Seeking help to pay the hospital medical bill for my mother

Hello Community members, my name is Arvind kaur and I am on a temporary visa in Australia. My mother came here to support me with my son, while I was studying. Unfortunately, she had brain stroke and hospitalised for 12 days in Sir Charles Hospital as she had to go through Brain Surgery. She had Bupa medical insurance, but insurance company did not covered much. I received the out of pocket medical bill of $54k, which I am unable to pay. I request all the community members to stand with me in this hard time and clear the medical cost. Thank you so much.
