The Australian share market has fallen across most sectors amid a worrying increase in virus infections, with investors looking to book profits after recent gains.

The benchmark S&P/ASX200 benchmark index closed Wednesday down 81.2 points, or 1.32 per cent, at 6,075.1 points, while the All Ordinaries index finished down 76.2 points, or 1.22 per cent lower, at 6,192.6.

The Australian dollar gained as risk appetite returned on stimulus hopes globally. It was trading at 71.34 US cents, sharply higher from 70.38 US cents at Tuesday’s close.
