Westpac - "AUD/GBP has hit our  0.6650-0.6700 target and is probably due for at least stabilization, perhaps a pullback to 0.66 so long as the RBA continues to threaten further easing and with sterling perhaps a little oversold. Trade below 0.65 would probably require the RBA to indicate it will cut rates further than already priced in. For AUD/GBP to make another run at Aug12 highs around 0.68, we are likely to need to see another round of BoE QE, which is not our base case."
