Help our Darling Mom get the care she needs

Hey guys, thanks for taking the time to read our recent devastating news about our beloved Mom, Wife, Friend and just all round Angel of a person.
Mom recently had a stroke as they were packing the last of their belongings in South Africa, to finally make the move and be with myself, my wife, their 2 grand daughters my brother and his wife. 
Nobody can prepare you for such shocking news, those of you who know can relate. 
To make matters even worse was that following the scans Mom was diagnosed with Advanced lung cancer......absolutely devastating!! 
The waiting list in South Africa they were told was 4-6 months and none of us were prepared to wait that long, considering they were told by the Dr that un-treated, Mom May have 6-12 months to live!!
Mom wants to be close to us and have her family around her whilst she tries to fight for time on earth. 
Nodody can prepare you for this news 8 days prior to them moving to Australia. 
Another blow to our progress was that their 804 Visa does not allow them Medicare ( although British Citizens) as they came from a non-Commonwealth Country. 
Mom and Dad sold everything for a better life in Australia to find out this tragic news.
we all know that the Rand does not go far in Australia, let alone any other country! 
Mom and Dad are looking at tens of thousands of Dollars for treatment, not even taking into account palliative care etc, that’s their life savings gone.
If you guys could help out with some spare dollars and spread the word, it will go a long way in keeping our beloved Mom with us for longer, she is far too young to be leaving us so soon.......guys all of us thank you from the bottom of our hearts!!! Please say a prayer for her, that would be really appreciated. God Bless xx
