The Australian dollar remains in sideways trade amid continuing uncertainty over the US political stalemate.

At 0630 AEDT on Wednesday, the local unit was trading at 94.37 US cents, slightly up from 94.33 cents on Tuesday.

Uncertainty remains over how long the partial US government shutdown will continue.
