Wow! It's terrific they're paying her accommodation costs.
I did a little bit of investigation into VPTAS myself and it turns out it's only for rural patients, and I think you come from Melbourne so may, therefore, come under a different scheme (or none at all). It is, however, a misperception that the scheme is only for pensioners: the main difference, as far as I can tell, is that non-pensioners have the first $100 deducted from their payments.
We have a lovely rheumatoid arthritis moderator here at HW. Her name is SydneyJo and, as you can tell, she comes from Sydney. She has Crohn's, too, and I've dropped her a note to see if she might know of any way that you and your wife might be able to get a little more help with out-of-pocket costs etc.
btw, I'm really impressed that you can use the net in your hospital! I haven't found a hospital room yet with connectivity: how are you doing it? Are you using a laptop, or do you have some sort of smaller gizmo?
