That ain't much
The AUDUSD moved to a high against the highs from June 7th and stalled for the 3rd and 4th time today (see green circles in the chart below).

The fall to the low stalled for the 7th time at the 0.75218-24 area (see red circles).
That is about the 44 pips that has confined the range over the last 4-5 trading days. That is not a lot of a range.
IN between is the 100 day MA at 0.7555, the 100 hour MA at 0.75397 and the 200 day MA at 0.75305.
Yes the price has not really reacted to those MAs. The price has traded above and below them at various times over the last 4 or so days. Clearly, "the market" is unsure of the directional bias for the time being, but it will make up it's mind in due course and knowing the levels is paramount if trading this pair.
PS making the waters even more muddy is on the daily chart, the 50% retracement is at 0.75389 - right between the 100 and 200 day MA lines (see chart below). This simply confirms how the market is unsure. It needs a push.

What might give the pair a push?
China releases industrial production and retail sales in the new trading day.
The FOMC decision could have and impact (along with US retail sales tomorrow. IN Australia, employment will be released on Thursday (Wednesday at 9:30 PM ET/Thursday at 0130 GMT). All those could be a fundamental catalyst to give a push.
Honestly, though it can be anything that gets it out of it's funk. Markets/traders get antsy when ranges are really confined. They may just give it a shove and look for follow through selling or buying. When the range is only 44 pips, it does not take much of a move to get things out of the range.
