AIDS: Australia's policies regarding AIDS-related services are progressive. As a result, most Australians enjoy approximately equal access to care, regardless of income; only those physically distant from health care facilities receive diminished services. The health care system is funded through general revenue taxes, currently at 1.4 percent of income. The chargeback system for physicians allows them to either accept the governments pre-set fees for services, or add a surcharge. As a result, some physicians have reduced the quality of services so that they can see more patients per day. Generally, the Australian history of HIV/AIDS care coincides with the culture of providing safety nets and systems that are fair and equitable. Australia was a pioneer in needle and syringe exchange programs. Drug trials in Australia have been hampered by both a small potential market for the drugs (Australians account for only one percent of the market for worldwide pharmaceuticals) and by a regulatory climate that is difficult for the drug manufacturers to work in. Overall, the Australian system works well, but it remains in conflict with political pressures to cut costs.
