And to do the latter, you need to get the Aussie down," said Shane Oliver, head of investment strategy and chief economist at AMP Capital Investors.
Banks lent support with National Australia Bank and Commonwealth Bank of Australia higher by 1 percent each after posting record profits earlier this month.
