The Australian dollar is close to parity with its American counterpart.
The last time the two countries' currencies were on a par was the early 1980s.
AMP Capital Investors chief economist and head of investment strategy Shane Oliver says while some exporters are suffering, a weak US dollar is needed to reboot a stuttering American economy, and bolster a muted global recovery.
He says the Australian dollar seems to have "got up a good head of steam" due to international factors such as talk of more monetary easing in the United States, and also a run of strong economic data within Australia.
