The legislature finances the premiums for all private health insurance cover, including clinic and subordinate additional items, by 10%, 20% or 30%, contingent upon age. The ALP and Greens have for quite some time been against the refund, alluding to it as "white collar class welfare". The Rudd Government declared in May 2009 that starting at July 2010, the Rebate would progress toward becoming methods tried, and offered on a sliding scale. While this move which would have required enactment was vanquished in the Senate at the time, in mid 2011 the Government declared plans to reintroduce the enactment after the Opposition loses the equalization of intensity in the Senate. A revised form was passed on 16 October 2008. There have been reactions that the progressions will make numerous individuals drop their private health insurance, causing a further weight on the public clinic system, and an ascent in premiums for the individuals who remain with the private system.
