However, efforts have been made by the Department of Health and Ageing to prevent low-income earners from having to pay either the Medicare Levy or the Medicare Levy Surcharge.
According to the department's 2012-13 Health Budget, singles who earn up to $19,404 per year and couples who earn up to $32,743 per year are exempt from the levy.
If a couple has any children or dependent students living with them, an extra $3,007 is added per child or student to this taxable income threshold.
For pensioners below Age Pension age (which is between 64 and 67 years old, depending on the year you were born), those earning $30,451 per year are not required to pay.
Non-residents, war veterans, foreign diplomats and blind pensioners, among others, are also exempt.
The Medicare Levy Surcharge is an extra payment tacked on to the Medicare Levy. It is required of those who do not have a Complying Health Insurance Product and have a taxable income over a certain amount.
If you are single and earning less than $84,000 a year, or your family's collective income is less than $168,000 a year, however, you are exempt from paying this surcharge.
