SYDNEY: The Australian and New Zealand dollars were again burdened by global risk aversion on Thursday as tensions in the Middle East simmered, while domestic jobs data proved too mixed to offer any support.

Bonds also took a beating as Treasuries extended their recent sell-off, sending Australian 10-year yields to the highest since mid-2011 at 4.76%.

The Aussie eased 0.3% to $0.6317, having already been dragged off a $0.6394 high the previous session as world equity markets slid. Major support now lies around $0.6287.

The kiwi dollar was near it lowest in 11 months at $0.5846 , having shed 0.7% on Wednesday to breach support at $0.5860. The kiwi has been struggling since a surprisingly low reading of domestic inflation lessened the chance of another hike in interest rates.
