The selling of Aussie for euros, which has been a very crowded trade recently, pulls it back against the US dollar, taking it 0.4 percent lower on the day to $1.0440, from $1.0470 in early trade.
The euro powers up to five-week highs at A$1.1936 , having broken major resistance at A$1.1850 as investors trim euro bearish bets. Charts indicate minor barriers ahead with scope seen for a move to A$1.20-A$1.21.
Euro has gained nearly 3 pct since it hit a record low of A$1.1597 earlier this month.
Likewise, the single currency climbs to four-week highs around NZ$1.5424 against the kiwi.
Euro strength weighs on New Zealand dollar which drifts back to $0.8081 against the greenback from an opening $0.8110. It briefly touched a one-week high of $0.8144 overnight.
Near term support around $0.8060 with the overnight high of $0.8144 likely to cap the topside.
