The Australian dollar has hit a fresh six-year-low after a landslide `No’ vote in Greece’s bailout referendum.

At 1200 AEST on Monday, the local unit was trading at 75.05 US cents, down from 75.84 cents on Friday.

The local currency dipped below 74.52 US cents in early morning trade, it’s lowest level since May 2009.

Overnight, Greek voters rejected more austerity demands from international creditors, fuelling expectations of a eurozone exit.

OANDA Australia and Asia Pacific senior trader FX Stephen Innes said investors were taking a very cautious approach to the market after the result, but the vote outcome wasn’t the only factor influencing the currency.

“Although we’re seeing some risk-aversion trade vis-a-vis the Aussie, last week’s 10 per cent drop in iron ore price is definitely weighing on sentiment,” he said.

Mr Innes said that while traders will eye the next chapter of the Greek saga, “regional developments in China equity markets along with commodity prices should weigh heavy on Aussie traders’ positioning today”.

Meanwhile, the Australian bond market was firmer at noon.

The September 2015 10-year bond futures contract was trading at 97.020 (implying a yield of 2.980 per cent), up from 96.885 (3.115 per cent) on Friday.

The September 2015 three-year bond futures contract was at 98.030 (1.970 per cent), up from 97.920 (2.080 per cent).
