The S&P/ASX 200 index (xjo) fell 24.32 points or 0.4 percent to 5,781.5 points by 0055 GMT. The benchmark eased 0.2 percent on Friday.

On the brighter side on earnings, steel manufacturer Bluescope Steel (BSL) hit a near 6-1/2 year high after tripling its underlying profit for the half-year ended Dec. 31, 2016, and announcing a share buy-back of A$150 million. .

Energy stocks were also down, with the energy index .AXEJ shedding as much as 1.3 percent and on track for its fifth consecutive session of losses.

Supermarket operator Wesfarmers (WES), which went ex-dividend, dropped 2.2 percent and was the second biggest drag on the benchmark index.
