AUD/USD is struggling as one would expect in a market that is suddenly looking risk averse after weeks of binging. The loss of 0.8180 support is a big blow technically and suggests the pair is in the process of topping out for the medium-term. Some would take a sustained break of 0.9110 as confirmation that a top is in place and that a significant correction needs to play out.
Selling rallies toward the 0.9180 level looks like the way to go near-term.
