Today's analysis: AUDUSD Gains Momentum Amid Hawkish RBA and Technical Resistance.

The AUD/USD is expected to rise due to a softer US Dollar, improved risk sentiment, and the hawkish stance of the RBA, which kept rates at 4.35% and indicated potential near-term hikes. Technically, breaking above 0.6640 could push the pair to 0.6770, despite resistance from the 50, 100, and 200 SMAs on the 4-hour chart and challenges from China's sluggish economy. Key support is at 0.6521.
