The underlying component data revealed some interesting trends which NAB said would be worth monitoring. Trading and profitability eased back slightly from their July highs, but conditions in those categories remain elevated. Following consistent jobs growth in recent months, there was a notable pickup in the employment index in August. There was also some evidence that positive trends in the labour market may be flowing through to higher wages. In what could be good news for Australian consumers, the labour costs index rose to 1.2 in August from 0.7 in July.
