How much to pay?

Hello,

silly questions, in NZ, we don't pay for the healthcare system, in AUS once we have applied medicare, do we have to pay the Levy? and how does it get charged? do we notify work once we have applied for Medicare?

also how is the special levy gets charged? if we take out private insurance, does it mean we don't have to pay the special levy at all? and can claims certain percentage of the insurance premium paid ?

thanks for answering the question!
