Australia's share market has wiped most of the week's gains in two sessions, as a rising greenback and global growth concerns dragged metals prices lower.

The S&P/ASX200 fell 82.4 points on Friday, down 0.92 per cent, to 8,828.7, as the broader All Ordinaries lost 79.5 points, or 0.87 per cent, to 9,047.3.
