Senator RUSTON (South Australia—Manager of Opposition Business in the Senate) (15:01): Despite the rising the cost of visiting a GP and plummeting bulk-billing, your government has refused to state that the aim of this measure—that is, the tripling of bulk-billing—is to increase the rate of bulk-billing by GP appointments in Australia. Minister, can you guarantee that the rate of bulk-billed GP appointments will increase as a result of the measure that was introduced on 1 November, and by how much?
