Australian shares tumbled on Tuesday, with negative sentiment on the financial sector spilling into all sectors ahead of a central bank policy decision.

The S&P/ASX 200 index (xjo) fell 66.767 points, or 1.2 percent, to 5,687.7 by 0312 GMT.

The Reserve Bank of Australia (RBA) is expected to stand pat on its 1.5 percent cash rate at its monthly policy meeting later in the day.

"Generally the market is down today because of banks and some profit taking in the utilities and the property sector," said Bill Keenan, general manager of direct equities research at broker Lonsec. "The utilities sector especially have had a very good run in the past few sessions."

Keenan said the RBA will hold rates, declining to raise them "because the growth rate of the economy is not that strong at the moment".

Data showing a narrowing current account deficit in Australia, at its smallest in more than 15 years last quarter, also failed to cheer the market.

The financial sector, out of favour since the imposition of a bank levy by the Australian government on the "Big 4" banks and Macquarie (MQG), declined, with its index .AXFJ 1.2 percent lower.

Utility companies AGL Energy (AGL) and Origin Energy (ORG) lost 2.5 percent each.
