AUDUSD bear flag 4th wave correction

Similar story for AUDUSD. The difference is that on a bigger scale, we are in a impulsive down trend, and this pair is less sensitive to Greece drama compared to EURUSD. I thought the bear trend would resume in US session but the intraday triangle got broken and I switch to bull. If the coming leg up is the final one, it could potentially be very stretchy. The upper bond to valid a 4th wave view is 0.75250, but I see 7500 even number to be very strong resistance.
