Amaroo's comment above on the AFR article (which I also read) is spot on why the AUD won't fall. Regardless that the AUD is seen as a quasi-commodity play and certain parts of the mining sector have seen a softening in their base metal prices, the fact is that the Govt is bringing in Billions by offering bonds (with a Triple A rating), at rates unable to be obtained in Japan, USA and most other countries - with no end of the appetite from either counterparty in sight. Even taking into account inflation and the possible losses on the forex market, a positive real rates of return is very attractive to cash holders who otherwise would obtain perhaps a 0.25% nominal yield and a negative real rate of return when factoring inflation.
Thus I think it will hover on average at $1.05 but trade in a range of +-2c depending in the relevant strength of weakness of the USD and the outlook for China's growth rate to climb back to between 8 to 10%.
Haven't looked at the markets for a week, but weakness in the AUD will be due to strength in US (markets thinking the fiscal cliff will be averted by agreement between Democrats and Republicans) or continuing weakness in either Australian or Chinese numbers (growth, unemployment going up, retail trade or manufacturing down)
