How would it be fraud? You are an Australian resident, eligible for Medicare, you are using the drugs while here, overseas and when you return. The only way it could be fraud is if you were in supplying the drugs to someone else.
And it can't be fraud when last year we were able to claim our overseas cycle costs in our medical out of pocket costs for income tax. If it was fraud to claim Medicare it would be fraud to do that, and my accountant assured me it was legal to claim those costs. (The only reason you can't claim this financial year is they have changed the rules and no medical oop are claimable).
That is shocking fear mongering!
