You can claim later I think (had to fill in some special thing from the ATO) - it isn't specific to hearing aids, is just for net medical expenses

DH is trying an online company based in Melbourne this time. BlameySaunders - is a self-fit system (they were on the new inventors!) They arrived today after ordering on Sunday, he is very happy so far - cost $3500 which is less than we paid for the last pair 5 years ago and a lot less than the 7 to 12,000 that the company he got those from had quoted.

I do think it is odd how differently hearing aids are treated, not being able to hear significantly effects your employability.
