The Australian dollar trading 25 ticks off the session low at $0.9172, close to Monday's three-year low around $0.9110. The Reserve Bank Of Australia facing bigger risks to growth and stability given the end of the Fed's QE and problems in China left the official cash rate at 2.75 percent for a second month. The decision was anticipated widely by investors. The currency is down about 14 percent since the peak in April.
