The Aussie dollar has done what against the Euro??? Stuff all. The yen & US dollars are dropping the Aussie dollar holding firm along with the Euro. This is meerly signalling the weaker US economy while everyone else buys gold as a hedge, hence the present (high) price.
With all the talk of an imminent attack by the US on IRAN the dramas in Turkey, gold is going no-where but sideways or up IMO so good luck with your short.
