Just adding that in case you were not aware, you can claim out of pocket eligible (this would be classed as eligible) medical expenses on tax. Once you hit $2000 out of pocket expenses, you can then claim 20c in the dollar after that of out of pocket medical expenses. I think this is the right amounts. You can go to the ATO website and get a better idea.
This would mean all out of pocket medical expenses for all the family once you hit the threshold.
