Yes. There is a government rebate that is available to a taxpayer whose eligible net medical expenses in the year of income exceed $1,500 (net of Medicare and any health fund refund). The amount of the rebate is 20% of the excess over $1,500 but cannot exceed the amount of tax otherwise paid. The rebate is claimed when the patient lodges their annual income tax return.

For example, a patient undergoes Invisalign treatment at a cost of $6500. Assuming the patient can claim $1000 back from a private health fund and none from Medicare, the rebate would be as follows.

[($6500-$1000-$0) – $1500] x 20% = $800
