GBP/AUD Cup & Handle

I was looking to go short on this pair until I came across this cup and handle pattern on the 1hr time frame. As you can see it's hit some support around the 1.64079 area, I'm still sceptical as this is occurring on the 1hr time frame and I usually stick to 4hr, daily and weekly charts but if I see some bullish indicators I'll enter a long position.
