China has also played a part by accepting more moderate growth at home and thus restraining demand for Australia's commodity exports, leading top miners such as Rio Tinto and BHP Billiton to announce a slowdown in future expansion plans and job cuts.
The Asian giant is Australia's biggest trade market and the single largest buyer of iron ore. It helped Australia avoid recession during the global crisis by unveiling a 4 trillion yuan ($635 billion) stimulus package that led to a wave of infrastructure development and demand for resources.
Australia's mining investment in the year to June 2013 is expected to total A$109 billion, or nearly 8 percent of GDP, way above the long-run average of 2 percent.
Even after Tuesday's cut, Australian rates are still among the highest in the developed world.
With rates near zero in the United States, Japan and Britain, those countries have taken ever more exotic stimulus steps including buying massive amounts of government debt.
