Someone weigh in if I'm wrong. It does have cover for things like hospital stay in a public hospital, and most of this person's medical bills (even the physio) should be covered in the public system with a diagnosis of GBS, but it sounds like they've gone for private cover? which is really expensive with shorter waiting times. And since they are both unemployed they would be losing out financially in a big way.

Not true mate. 5 funded sessions per year for a chronic condition. Your GP needs to refer you for this. I'm sure you'd need more sessions than that but every bit helps. Source: https://www.healthshare.com.au/questions/47966-am-i-eligible-for-physiotherapy-treatments-on-medicare/

I'm a cancer immunologist, and no, to my knowledge a vegan or plant based diet can't cure cancer on its own. Cancer is just your own cells gone rogue. Currently they can only be removed physically (by surgery), with chemotherapy or radiotherapy (both non-specifically targeting cells that are dividing), or by encouraging the immune system to recognise the cells as foreign and attack them (eg antibody therapy, CAR T therapy, checkpoint inhibitor therapy). Nothing in a vegan diet is, to my knowledge, either harsh enough or specific enough to tackle cancer.

The regulator changed the standard at the end of 2012.

Which therapy data do you mean? Precision medicine is playing an ever increasing role and there's huge potential here, probably limited only by cost. It can determine which chemotherapy or immunotherapy drugs have the best chance of success for each individual patient, giving each person the best shot at remission right out of the gate, reducing trial and error. Things like hormone receptor expression by a patient's breast cancer cells - that's a form of precision medicine in current use, as it immediately tells the clinician something about the likely aggression of the cancer and whether hormone blockers are likely to be useful or useless. One day i think it will be fully individualised, like a treatment fingerprint.
