Here's a weekly chart for the Aussie Dollar v. USD.
Everything is pointing up at this stage and looking strong. Momentum has just turned positive, MACD lines have just crossed and stochastic is nowhere near overbought yet. Being a weekly chart, it will not take into account daily fluctuations which can be considerable so I wouldn't use this chart myself as a guide to trading not should anyone else!
I also looked at other weekly AUD charts. AUD/CAD looked very similar but charts with EUR, GBP and JPY do not look as strong or advanced. In fact those charts show sideways action as the weekly AUD/JPY chart below shows. This may mean that the USD is particularly weak at the moment rather than great AUD strength.
