SYDNEY, April 1 (Reuters) - Australian shares ended lower on Friday, weighed down by sell-offs in the major banks.
The S&P/ASX 200 index .AXJO dropped 1.64 percent, or 83.385 points, to close at 4999.400.
The Big Four Australian banks were a major drag on the index, led by a 2.6 percent fall in Commonwealth Bank of Australia CBA.AX and a 2.1 percent drop in National Bank of Australia NAB.AX .
The close put the ASX down 1.5 percent for the week, the second negative week in a row.
