The All Ordinaries closed down by 51.2 points, or 0.72 per cent, at 7060.2.

The energy sector had the steepest decline, 3.41 per cent, after US crude oil prices fell on rising coronavirus infections.

The larger materials sector dropped 2.96 per cent after a drop in iron ore prices.

There was a slightly poor lead from Wall Street, which is in the midst of quarterly earnings season.

Some companies showed the toll the pandemic has had on business.
