Long Aussie is one of the most crowded trades right now, so positioning wise it looks ripe to fall. Plus it's susceptible to bouts of risk-off behvious such as we're seeing in the market today.
Gold looks soft (no pun intended) and usdzar is doing stops through 7.7250 and above all the way to 7.8310
The only issue is that the RBA are way ahed of the pack and there's an elephant graveyard full of smart guys who tried and failed to pick the turn on this, so beware, and job around to give yourself some wiggle room.
